Boatbuilding in a Nation of Two Finger Texters and Page Swipers

One of the memes of modern American culture is we have lost our DIY aptitude (a characteristic particularly attached to the millennial generation). We dont fix our cars, we dont fix our houses, we dont build things..we pay someone else to do it. I was reminded of this when reading the geeky but very informative Professional Boatbuilder magazine (by the same publisher of Woodenboat magazine).. They did an article on Chesapeake Light Craft, the plywood boat-kit builders based here in Annapolis. Chesapeake Light Craft spends an inordinate amount of time trying to make their plans and kits so comprehensive there is very little room for error. I then read the following paragraph and my jaw dropped.
Some customers are so unskilled that it would be better not to sell them a plan or a kit. "So many people these days cant read plans at all. When a part is symmetrical around an axis and the plans only show half a part, some people build half the part. Thats happened twice in the last month. One guy made half of the deck and the bottom. We were very nice. I guess if you cant laugh, you have to cry...You cant make assumptions about anybody."[Professional Boatbuilder, Number 152, pg. 26]

Hmm! maybe we are becoming a nation of hopeless klutzes.

A Good Book for Sailors

I promised you no more book reviews in 2014; but the new year is in full swing.  This book was given to me at least several months before we left NY in early October by Judy, a dear friend of mine and Lenes, who sailed with us for a few days in the Turks and Caicos in early 2012. Her book group read it and liked it even though they are not sailors; sailors will appreciate it more.

It is about three generations of the Scottish Stevenson family. Robert Louis Stevenson would have been the fourth had he not forsaken engineering for literature to the great disappointment of his family and with a personal sense of shame. The three generations built most of the lighthouses of Scotland and supervised their operation.


Two threads are woven through the book. One is the biographical -- the marriages, births, deaths and personalities of the men, mostly the men, and their wives-- a personal story. The other and vastly larger part tells the story of how they built the lighthouses, against all sorts of obstacles.

Both parts were interesting, though the later was far more interesting to me. Much of the personal part relates to the efforts of fathers to induce their children to follow their footsteps into the family engineering business. Robert Louiss father was himself drawn to literature but was forced to abandon it to study engineering, which he then tried to force his son into.  The fathers drove themselves very hard and demanded as much from subordinates and their children. Except for the first generation, the men suffered from weak health, which was exacerbated by long days of strenuous physical activity in cold wet places.

There is a skeleton family tree which is incomplete, in the sense that the text names various members of the family who are described on the tree merely as part of, e.g.,  "two daughters."

More irritating to me, the sketch map of Scotland at the front shows the names of some of the cities, islands, firths and lighthouses, but is terribly incomplete. The lack of a proper map in a book that is about locations was the major obstacle to my enjoyment of the book. The author refers to so many places, possibly presuming that only persons who are quite familiar with Scottish geography would read her book. The Stevenson family also designed much of the "new city" of their home, Edinburgh. I tried to use Google Earth to figure out which roads were joined with others. Subsequent changes to the landscape are what I blame for my inability to complete that task. There are sixteen plates showing the most famous lights and portraits of the Stevensons, but none of Edinburgh. Bathurst is very able to draw pictures with words, but maps would be so much better.

Bathurst also mentions big events in Scottish history with which I had not even the vaguest idea. Jacobites were Scottish revolutionaries, and "The Clearances" was the process by which the landed gentry forced the "highland" Celtic peasants off the land to make more money from sheep. This contributed to the Scottish Potato Famine. Some of the "crofters" went to the "lowlands", areas in the southern and eastern parts of Scotland, others to America. But all this I learned from Google after Bathurst merely mentioned the terms.

Another minor defect in the book is the absence of any footnotes to support the statements made. I would like to know if a given statement about a person is the authors conclusion from one or more documented episodes, from her reading of his letters or journals, or based on a secondary source: either a biographer or a newspaper. I am used to David McCulloch and Dorris Kearnes Goodwin, who give you the source of every statement in their books. It is not that I want to read all of those footnotes, but one feels more comfortable knowing that they are there. Ms. Bathurst does include a bibliography and she seems quite knowledgeable and won my trust after a while.

Most of the chapter titles are the names of the most famous of the lighthouses, each more challenging to build than the last, by which successive generations of  Stevensons made their reputations. Bathurst makes the point that each lighthouse needs to be designed to fit the requirements of its site, not aesthetically (though that was true too) but from the viewpoint of the engineering involved, especially the base on which it was to be built. Earlier lighthouses had been knocked down by the waves.

There were also political battles to be won, by the Scottish Lighthouse Board against British control, and by the builders against the wreckers who made their living from salvage and accurately perceived that the lighthouses would diminish their livelihood. Religious people argued that God had put the shoals where he did, and if he had wanted to, he would have put lighthouses there too. How can one argue with such a person.

Bell Rock, the Stevensons first, was built on a rock that was underwater at high tide. So work could only be done there, until the tower was partly built:  at high tide, in daylight, in the summer and in good weather. Not many hours of work per year.

The process of building the lights seemed to me like a scaling of Everest, where one has to establish a series of base camps leading to the final assault. In the case of lighthouses, these were to locate a quarry, create a remote land base where the materials could be assembled, acquire a ship to convey them to the rock, and then create: a landing place, a smaller temporary structure in which the workmen could live, the ring cut in the rock for a foundation, the foundation, the tower and finally the light at its top, before hiring and training the keepers.  And in some locations  during big storms, the waves threw tons of salt water over the top of and  into uncompleted lights and tore away blocks of granite weighing several tons.

The story also tells of the advances in lighting technology during the years, from a coal fire on a hilltop to candles with parabolic mirror reflectors behind them, to early glass lens concentrators, to Fresnel lenses.  And fuels advanced from whale oil to paraffin and even, after the Stevensons, electric bulbs, and the automation of the lights with consequent elimination of the keepers.

Bathurst includes other advances in safety at sea such as lifesaving organizations with boats, life vests, Plimsoll lines (to prevent overloading), licensing in an attempt to require competence and, in an epilogue after the Stevensons era, radio, GPS, and EPIRB. Bathurst notes the Volvo phenomenon -- as safety and navigation equipment improves, recreational boaters take greater chances, like Volvo drivers who drive faster because they are lulled into a false sense of safety by the safety built into their vehicles. A cautionary advice to all sailors.

My enjoyment of the book was enhanced by two others I have read. The first half of Robert Louis Stevensens "Kidnapped" is in essence a counterclockwise circumnavigation of Scotland, punctuated by a shipwreck, which, took place on the Isle of Erran, near the site of Skerryvore, the largest, tallest Scottish light.
The wreck was before the light was built. I added the route of the hero of "Kidnapped" to the crude map in my book. The second was Joshua Slocums Sailing Alone Around The World, reviewed in this blog, which included a gift of books from Robert Louis Stevensons widow to Captain Slocum.

The first in the line of Stevensons began as a metal worker who invented polished curved mirrors to concentrate light. He built lighthouses to provide a market for his polished mirrors. He was self taught and valued education and the dynasty grew up coincident with the development of engineering as a profession. He considered himself inferior because of his lack of a classical education.
Here is Robert Louis, painted by his friend, John Singer Sargent, obtained in August 2015 at a show at the Met Museum of  Art.

Many people love lighthouses as works of beauty. Our Maine trip in 2013 has pictures of many of them. And one underestimates the value of lighthouses to navigation if one thinks them as useful only at night. As God led the Children of Israel through the desert for 40 years (Exodus 13) by manifesting himself as a pillar of clouds by day and a pillar of fire by night, lighthouses guide mariners by their light by night and their bulk by day.        A good read.

December 25 31 Final Work Day and 2015 ROUNDUP A Great Year!

I had planned on more than one final work day before the end of the year, what with such good warm weather so late this year but a wrenched back put the end to that. The last work day was devoted to the cabin sole. I want to check out how good the pieces I have done look, before committing to do the rest. I have been doing the bottom side of this flooring to encapsulate the wood in plastic to avoid a softer surface on which mildew could potentially grow, not that mildew has been a problem for ILENE.

Another non-boat day for calling Dave to make an appointment for January to work with me on cleaning and lubricating the winches and steering gear and fixing some pesky wires that no longer transmit sound to the cockpit speakers, etc. And then I had to figure out what parts and supplies I need for these jobs which involves a lot of calling and computer searching before ordering. But the non-boat water relatedday involved some play too: While my two favorite ladies, ILENE the boat and Lene, her mate, are thoroughly land locked on the hard in New York in late December, I had fun with Dames at Sea:

And while laid up resting the lumbar-sacral region I have been reading this months selection of my book group (all right, it was my suggestion): Jules Vernes "20,000 Leagues Under The Sea". So avid readers may expect another book report soon.

So what can I say about 2015. I sure got a grand dose of sailing and boating related activities - a lot of water under our keel. It was a very satisfying year, the year that my beloved Lene finally lost her ability to continue to claim "Im really not a sailor.".
We began the year in Fort Lauderdale, Florida, to which we returned on March 5, after a lovely multi-stop visit to Key West Florida and 20 miles past that. Next were a lot of great passages and ports until we got back to the Harlem on May 26, the 146th day of this calendar year. Also: a two day trip down to Gravesend Bay to sail with LHermione, 17 days on the Club Cruise to Block Island, five days with Bob on s/v Pandora from The Connecticut River around Montauk Point to Hampton Virginia and 22 additional days of day sailing from our mooring and back for a total of 190 sailing or living days. My career high total, and possibly a number that what with aging, may never be equaled or exceeded. And as they say in the infomercials: "But wait, theres more! Add on 21 days involving the water that are not related to living, sailing or working on a sailboat, and 25 work days on ILENE. (Or course, many of the cruising or living days also involved some boat maintenance and repair, but those are not counted as lowly work days.) So the grand total this year was 236! A goodly percentage of the 365 available. I have nothing to complain about.

The way I have looked at it, sailing is a social activity with much of the fun coming from sailing on other peoples boats and inviting them onto ours. Most of the sailing days, including the first 146, were aboard ILENE. But 5 were on Pandora, 4 on Deuce of Hearts, 2 on Ohana and 1 on Pas de Deux, totaling 12 -- 178 out of the 190 were aboard ILENE.

Continuing my lifelong desire to share my boat with present and future friends, a total of 38 different people in addition to Lene sailed with me on ILENE, at least once day this year. Some sailed multiple times and others, not counted among the 38, did not sail, but came aboard for meals. Friends of mine, of Lene, from the Yacht Club, from our Synagogue, and from our condo.

And 2016, with a three month cruise to Nova Scotia as a goal, starts in a few hours. Before Nova Scotia comes after both a week with Bennett and Harriet (in whose home we will celebrate the New Years arrival) on s/v On Eagles Wings in the Virgins in early April and a week with Lenes family on a cruise liner from Galveston Texas in the Gulf of Mexico in early June.

On the macro level, the world may be going to hell in a hand basket with democracy threatened by big money at home, climate change destroying the world, gun nuts (both domestic and foreign) running amuck, a certain redheaded egomaniacal reality show star trying to move us from love toward hate, educational standards low and sliding, etc. But all I can say is that focusing in on the micro level I am blessed to have such a great life. And I recognize and am very grateful for the bounty bestowed upon me and my family.

Deciding On A Boat To Build

I finally narrowed down my boat search.I have been tormenting myself with buying or building.After doing the math,I have come to the conclusion that I can build a new boat cheaper and better than buying a used turn key boat.Most of the turn key boats I looked at really needed work.Fiberglass boats are the worst.Most have water logged flotation foam that causes the wood stringers and transom to rot from the bottom up.Ive stripped (and helped strip) and rebuilt a few boats.It is not fun in a big 25+ foot boat.Its faster and easier to start from scratch.

 Most of my boating will be on larger lakes and the ICW around South Carolina,North Carolina,and Georgia.I do plan to take the boat around the Great Loop,so it must be a sea worthy design.I searched for years for a design that was easy for a first time builder with some basic carpentry and boat building skills.There are a lot of excellent boat designers with plans out.Most are more suited to the advanced DIY builder than a first timer with basic skills.Out of all the producers of plans,I decided on Spira International.Jeff Spira is the designer of all the plans.The best thing about his plans,is access to Jeff Spira himself.He can be contacted through his website or on facebook.He always gets back in contact with you within time.He is a busy man tho.So please give him a few days,he could be away.

 My base criteria for a boat is as follows in this order.There are more variables,but these are the main ones.
1)Trailerable behind a full size pick up truck,van,or class C RV.
2)Shallow draft, 12 to 16 inches with the lower unit up.
3)Absolutely no more than 2 gallon per hour fuel burn at displacement speed.
4)Must have sleeping arrangements for four.
5)Must have full head with shower.

In my next post, "The Chosen One",I will review the Spira plans that I considered,a break down of build cost,and the plans I chose.

Honey,Lets get a boat.

Working on a July Launch Date for the Optimist

My brothers and I have slowed our building of the Optimist down to a crawl. However, my brother Darren has taken the lead and wants the first boat to launch on July 4th.

He has purchased sail, tiller and extension, blades (rudder, centerboard), gudgeons from APS - Annapolis Performance Sailing.

To protect the chine he has laid down a 2 inch strip of fiberglass cloth in simple-clear polyester resin. It should provide a bit of resistance to any "hard blows" on rocks that make up the shore of our part of Lake Ontario.

Polyester resin is quick to harden and very easy to sand. It costs about half the price of shipping epoxy to us. Its just a short drive to the auto parts to pick up a quart.

The need of keeping water out of the bilge of a metal boat

I always start my surveys on metal boats by using Thermal Imaging of the hull. This helps me locate the structural components of the metal boat. I am also looking for trapped moisture and/or water. If this is found, then there is a good chance there will be corrosion. Next I conduct an inspection of the bilge of the boat, including, anchor, sail, cockpit lockers, and lazarettes. Now I have a very good idea where to concentrate my UTM-audio gauge. I take readings of the whole hull, but will do more readings in the areas of concern.

When I see water in a bilge of a metal boat beyond what might be in a sump I get concerned. I would like to see dry bilges on all metal boats, but this is not always possible. On Tuesday I surveyed a steel trawler. Overall this boat looked to be in fair condition, but then I saw the water in the bilge, a lot of it! There was heavy scale in some areas because of the standing water.  I knew this was an area I needed to spend some time getting thickness readings.

The next day I did my audio gauge. My readings indicated plate wastage. In some areas I could not get a reading that most likely is caused by heavy scale. My visual inspection from inside confirmed the heavy scale. When I arrived at the boat I noticed some weeping from what I hoped was paint blisters. Then an hour later water stared streaming from one of the blisters. Just to think only the paint was holding this section of plate together.

The good news! The boat was out of the water it will not sink. Steel boats can fixed; by cropping out the bad plate and adding new. In a short period of time, she will be underway again.

The moral of this story? If you own a metal boat keep an eye on the bilges.

I will post photos in my next post.

Jet Propulsion for hydrofoil or maybe a prop and flex shaft

Very cool control system



The drive with the angle reduced improves losses 20% 4.3 Amps idling so only 300mA losses from the shaft. I think the steering should be integrated as a kitchen rudder behind the prop.




Reversing the shaft on a Turnigy D3542/4 Aero drive It a 1450 KV and should deliver loads of torque at 14,000 RPM on as 3C



Battery: 2~4 Cell /7.4~14.8VRPM: 1450kvMax current: 48A No load current: 4AMax power: 690WInternal resistance: 0.019 ohmWeight: 130g (including connectors)Diameter of shaft: 5mmDimensions: 35x42m



Above is a 47 mm prop I have a 57 to once I have the motor attached to the shaft sleeve I will do a power test in a tank see what thrust and Amps I get. With the fat end of 1 HP it should have plenty of clog to lift  it up on the foils.




The shaft is running in a good quantity of copper slip. Ran it on a 4C for a minute an the brass only got warm.



I think the body of the hydrofoil will be a lunch box. I think I will have the prop shaft attached to the rear foil

Perhaps the prop on the above can be placed in a tube like these designs



An interesting jet outboard very high outlet must cost power




Jet Propulsion for hydrofoil  





One thing as there is no transom the bulky scroll will always be in the flow and the outlet will be under water which will reduce the trust considerably.


If the outlet was up high it would work better also the riser would need to be streamlined







Or what about an EDF pumping air into a venturi like below

Carrying A Dinghy On A Boat

My situation is a little unique.I am building a boat and a dinghy.Carrying one,however,has presented a challenge because of my boat build.Most boats use a davit system and carry the dinghy on the swim platform or transom.Some carry them on the roof.At first,I thought the roof would be a good place,but as pointed out to me on a forum post,its not.Carrying on the roof can make for a dangerous situation in rough water.Its hard to launch a dinghy while its swinging on a boom or crane.It could crash into the boat and break stuff.It could break loose and hit someone or sink.In an emergency,the boat could sink before getting the dinghy in the water, taking the dinghy down with it.

Most production boats have a lot of freeboard or height of the sides above the water.The boat I am building doesnt have much freeboard at the transom compared to production boats.Because of my boats lower freeboard than most, presents some major challenges for carrying a dinghy.I cant run a full width swim platform because my I/O comes through the transom right in the middle of it.This rules out swim platform dinghy lifts.A transom mount davit could possibly work,but it would be of my own design.Production davits wouldnt be able to lift the dinghy high enough to clear the water or I/O,at least none that I have seen.Then there is the issue of carrying the dinghy across the back.The dinghy will be longer than the boats beam is wide.This could cause problems when in tight marinas or narrow channels.Any of these options would severely limit my rear visibility, thus blocking my transom and preventing my boats name from being visible to other boats.I do plan to tow my dinghy, on the days I plan to use it,if the weather is good.

Some have suggested that I go with an inflatable or folding Porta boat.Ive had issues with inflatables in the past and they are heavy for their size.Some folding boats are a little to flimsy to really carry any weight.I need to be able to carry roughly 800 to 1000 pounds.I dont think its possible,so two trips to shore will be required.Maybe I could pull a ski tube behind the dinghy with our supplies in it.Wait,I know!Ill toss the kids in the ski tube and put our provisions in the boat.They will love that.

My hull draft will only be 16 to 18 inches,so I could possibly drop anchor and wade to shore.Im not sure how my significant other and our kids will like that.Got to keep Mama happy,LOL.When I am in a marina,I will more than likely moor the boat, while we go ashore for provisions.If the area will allow for it,I could beach the bow and let everyone off ,moor the boat,and take the dinghy back to meet the family.When we return,I could take the dinghy back to the boat,bring the boat back to shore,and load up.Seems like to much work.Some places will allow boats to temporarily dock for a quick trip to town for supplies.that would be the ultimate solution.

I still have a while to go before I make a final decision on how to carry a dinghy.Until then,I will be looking and watching other boats and how they carry a dinghy.Im always open to suggestions.


UPDATE!
After some discussion on the Trawler Forum,I am considering adding a rear rack to carry my dinghy and to hang the rear canvas enclosure from.I feel that this rack needs to be removable.I only plan to carry the dinghy when I do the Great Loop Cruise.Every where else I will be able to dock or trailer the boat out.Here is what I had in mind for those that are scratching their heads trying to figure out what I am rambling on about.





More info on the boats in the picture can be found at Allweather Boats.

Edensaw Boatbuilding Competition A Sailing Dinghy Wins!

Most wooden boat shows have live boatbuilding; usually it involves a group of families assembling a quantity of small rowing skiffs which are then launched at the end of the weekend. At the Wooden Boat Festival hosted by the Northwest Maritime Center in Port Townshend, Washington, Edensaw Woods sponsors a boatbuilding competition where they move away from the typical novice boatbuilding event and open it up to a diverse group of boats from professional designers and being built by skilled woodworkers. In this years competition, built alongside the traditional dory and Irish curragh were two sailing dinghies. One of them, Richard Woods Zest singlehander, won the competition

Here are two of the boats on the beach after the time-limit for boatbuilding expired, ending all construction. On the left was a dory built only with hand tools. On the right is a 14 foot, V-sectioned sailing dinghy designed by sometime Classic Mothist, Stephen Ditmore. As the photo reveals, Ditmores team got the hull done over the weekend but the decking and rigging awaits.


Winner of the competition, designer Richard Woods on board at the initial push-off of his Zest dinghy. This is definitely a racing singlehander with hiking wings. (The hull is a relatively narrow, flat bottom shape.) The hull was completed by the team over the weekend and Richard was able to scavenge sailing parts from some of his other projects to get this design sailing in short order. I think the pushee in the photo is Michael Scott who owns several sailing dinghies including a couple of Classic International 14s and who is constantly feeding news tidbits to the blogmeister.


Instead of painting over the freshly applied epoxy, the Richard Woods team decided to apply a silver vinyl decal material over the hull (purchased at an auto supply store). Very distinctive, hence the boats name Silver Bullet.


Designer of the other sailing dinghy at the competition, Stephen Ditmore sailing his Classic Moth design. Unfortunately we have only seen his Moth show up once at Brigantine, New Jersey.

Geezer Bloggers gather around a Penguin Dinghy

I went over last weekend to help George A. of Mid-Atlantic Musings> move one of his boat collection into a U-Haul. It wasnt a Moth but a Penguin and was being collected by her new owner. Georges Penguin dinghy was one of six originally built in the 1960s by a guy named John Walton in Brigantine, New Jersey. This Penguin, most likely being the sole survivor of the six, was being rightfully reclaimed as a family heirloom by Johns son Bill, who had flown up from Texas.

In the photo below, George is going over the history of the Penguin with the blogmeister. Turns out George helped build the six as kid. He was on the centerboard trunk building crew. (Forgive the odd colors of the photo but I wanted to highlight the beautiful interior wood of the Walton Penguin and was working from a very dark I-Phone photo.)

And from the 1960s, here is the blurb on the Penguin from the magazine One Design and Offshore Sailing annual small class review, .

2015 Fall Season A List of Free for alls

Over the years this blog has featured some of the oddball regattas/sailing races where you take your oddball small sailboat and compete against a bunch of other oddball small sailboats. During the fall season there is enough of these events you could, if so inclined, hop-scotch up and down the East Coast of the United States.

They are (in roughly chronological order):

Sebago Cup - mid-September at the Sebago Canoe Club, Brooklyn N.Y.
A one race jaunt around Jamaica Bay. Im sure they would be delighted to see some out-of-town visitors and been told, even though this is Brooklyn, there is plenty of parking around the club. See comments for more info from SCC members.

SEBAGO CUP ----- September 19, 2015
Our annual cruising race!
This is an open class cruising race open to non-members. Fleets will be created upon the participation of at least two boats of the same class. Contact sailing@sebagocanoeclub.org for more information.
Skippers meeting - 11:30 am
Starting gun - 12:30 pm
Notice of Race
Sailing Instructions 


NSHOF Classic Wooden Sailboat Rendezvous- mid-September, Annapolis Maryland.
A one-or-two lap race around the Annapolis Harbor. The majority of entrants are classic cruising keelboats but there is always a smattering of small boats. This year John Z is entering his Classic Moth.


CLASSIC WOODEN SAILBOAT RACE, Sunday ---- September 27, 2015
NOR



MASCF (Mid-Atlantic Small Craft Festival) - First weekend in October, St. Michaels Maryland.

This is more of an event than sailing race but there is, on Saturday, a one-lap sailing race in the river starting around noon that is quite a hoot. I have done it twice in my Classic Moth Tweezer where I was racing in a division featuring a motley assortment of larger craft including Thistles, Core Sound 17s, Blue Jays, Celebritys, log canoes.

MASCF ---- October, 2, 3, 4, 2015

Zen of Daysailing A Dutch Valk and Jolle Segeln

Every once in a while I intersperse all my posts about planing boats, or racing, or boatbuilding with videos of people just enjoying a daysail and a day on the water. The wind is perfect, not too strong, not too light, the sun is out, the water temperatures are good for swimming. Sailing is best done with the feet up and a smile on the face.

The Dutch Valk klasse is similar size and original concept to the U.S.A.s Lightning class though with a squat traditional gunter rig. It appears the Dutch build them in fiberglass for recreational sailing - the PolyValken. (I think they reserve the wood ones for racing.) By the looks of this video, the Valk fits the recreational role superbly. (I like the cross thwart at the aft end of the cockpit allowing the skipper to recline and steer at the same time.)


Zeilen op de Kagerplassen from Muxio on Vimeo.

Jolle segeln is German for dinghy sailing. Here is a daysail in a true classic German dinghy, wood with traditional fittings. (Video settings doesnt allow me to embed.) Im not sure what the class is, maybe a reader can help out.

May 26 to June 21 Its Been A Long Time with Little Sailing But

Normally the summer time is the busiest blogging time, but after 146 days afloat this calendar year before May 27, this is a decompression time. I do not feel the urgent need to get out on the water every day, not that nothing water related has taken place.

I have gone on two of the Wednesday afternoon sails with the Old Salts, the new name for the revived Old Farts. First on PC Marks "Deuce of Hearts", a catamaran, and then on ILENE.  Mark has been instrumental in reviving this group this year. Four people came the first time and seven the second (me, Mark, Mike, Richie, Dave, Morty and Clara). And the G and Ts are just as good as ever. Both days we were graced with moderate light wind after lunch at the Club. The food at the Club is a bit pricier than last year, and the portions a bit smaller (which is good for our health). The food is simply much better quality and better prepared. On ILENE we cut through the channel behind Stepping Stones Light where there was very light wind and we were near a run, before heading to the Throggs Neck Bridge and back to Hart Island before heading for home. The wind changed direction with the result that we only did one jibe and one tack.

I also had a pleasant afternoon with Ilene, and Bennett and Harriet aboard their Beneteau, "Ohana". She moved nicely in very moderate air. Come to think of it, we have had a lot of very moderate air for June. The four of us had a good dinner at the Club after, trying out our new chef, Ann, who does good things to food.

And I crewed for PC Mark on Deuce of Hearts
with PC Erwin, visiting from Florida, and PC and Ms. Bob and Laura in the Clubs annual Rear Commodores Regatta, which was set up as a pursuit race of slightly less than five miles.
Lene and I had won this race on ILENE back in about 2008, on a pursuit-destination race to New Rochelle with, miraculously, only one jibe. In a pursuit race, the handicaps are computed for the given course in advance and each boat starts at a different time, reducing the collision-inducing madness when several boats want to be at the favored end of the starting line at precisely the same time. So, if everyone sails as projected, all of the boats should arrive at the finish line at the same time. ILENE had the biggest handicap back then and hence started last and passed every other boat in the fleet on the way to the win.
Alas, this year we came in tenth of twelve boats because we made two mistakes. The first was not getting to the starting line until almost a minute after our time. Stuff happens and this has happened to me. The second mistake was using the small jib until the third leg of the triangular course. Deuce of Hearts is set up like ILENE, with a larger headsail set forward of the jib; it has to be furled between tacks. With the smaller headsail we were just too slow. Another great feature of Deuce of Hearts is that the tack of the big headsail is mounted on a track and can be moved to port or starboard  from the cockpit to catch wind without messing up the wind in the main. We were untrained crew and the PCs figured out how to use this neat trick, but too late. I think Deuce of Hearts has a lot of potential to be a fast boat on the race track.

Part of the reason for relatively little sailing was the visit by Lenes niece, Barbie, her son Trevor (who we hung with in Amsterdam last June) and Anna, a 16 year old exchange student from Denmark who lived in Barbies home for the school year. So we had five folks in our apartment and they made it very clear that their jam packed week in NYC did not include sailing. But we did see sailboats  -- at the MOMA -- Seurats pointillist masterpiece.

And there were several days of planning for the Club cruise plus a Club weekend excursion to Sheepshead Bay in August, and Club participation in the July 4th parade up the Hudson with a full wooden replica of "Le Hermione", which brought LaFayette to these shores and participated in winning the battle against the British fleet that was intending to re supply and reinforce General Cornwallis at Yorktown. When deprived of such aid, Cornwallis surrendered to General Washington, thereby ending the military operations of our war of independence.

And four workdays, pickling the water maker, which we will not need this year, cleaning out the refrigerators and the bilge, putting up the new plastic enclosure to the cockpit for measurement for straps to tie it up out of the way in the rolled up position when needed and snaps to mate it with the sides of the dodger. Finally I did work on the solid cherry batten that holds up the ceiling in the salon, to accommodate the new hatch screen enclosure.

And arranging some sail dates, sending back the new stainless steel snubber line hook which was replaced with a smaller one that fits and holds onto the anchor line, reducing the cruising area of our insurance policy to save money and other boating related chores.

BoatBuilding A Mad Mothist does a Bottom ectomy

On modifying my Classic Moths Ive rebuilt decks, rebuilt daggerboard trunks, added buoyancy tanks, glassed interiors, but Ive never grafted a new bottom onto an existing Moth - performing a bottom-ectomy so to speak. British Mad Mothist, Jim Champ, former Cherub sailor, dinghy historian, amateur dinghy designer, current International Canoe sailor, and webmaster of the International Canoe website is doing just that to a fiberglass Skol he purchased.

Ill let Jim explain his project in his own words.

"The back story is I picked up this 1970ish Skol Int. Moth because I needed something to sail while a health problem was stopping me sailing my Int Canoe in most conditions, and besides, Id always fancied one. The fact that I am now about 5 stone too heavy even for a vintage Moth didnt deter me.

Anyway, the boat came out of someones garage roof, and I completely failed to spot, under the layers of dust, that at some stage the boat had been sliced off at the waterline and been given a new wood bottom, replacing the original glass. This was no problem until after a seasons use it became apparent that the wood bottom had been allowed to rot back in the day, and some crucial bits were now leaking badly as the water had re-penetrated.

So I ended up cutting off the wood bottom, and Im now building a new one, and learning about cold moulding while I am at it. Shape wise its roughly based on a Cherub I drew in about 1974 but could never afford to build.

What have I learned from this project? Not to be afraid of cold moulding, and when you do it use plenty of strips. I originally was trying to use quite large panels in order to minimize the number of accurate edges I had to cut, but actually getting the sides of the strips accurate is surprisingly easy given a small sharp plane and a block and sandpaper. Its definitely right to have too many strips rather than too few. Getting the length right on a very 3d boat, on the other hand was a nightmare, but in any rational new build that wouldnt be an issue. 2mm ply was definitely much easier than 2.5mm veneer, having tried both, but if you use ply you cant varnish because the smart money is youll go through the outer layer in some (or in my case, many) places when fairing up.

I did the boat partly in 2 * 3mm and partly in 3 * 2mm. The junction between the two was something of a pain and in any case I carried 3mm too far forward. The last bit of 3mm was definitely excessively 3d. Im sure the boat is somewhat asymmettric in that area because with the panels at 45/45 ish, bending the last bit was problematic. The first layer has a much bigger impact on final shape than subsequent ones, and in the transition on one side the first skin was 2mm and the other 3mm. It would probably have been better to suffer the horrendous cost of the 2mm ply and done the whole boat in that. If I were doing a new boat it would be 2 * 2mm ply all over with a glass skin inside and out, uprating the inner skin appreciably in the slamming area round the bow by adding inner glass over skin and stringers, not under stringers.

This was the first project I used a router on which was interesting. Vision really was a major problem, I guess my shop isnt that well lit because I found it really hard to see what the cutting edge was doing. For a long accurate cut to put a rabett in the glass topside (ouch, terrible thing to do to a cutting tool) I stapled a batten as a guide right along the boat and that was a major win. The other thing that helped with a router was to get a marker pen and colour the area I wanted to remove, which made it soo much easier to be confident about what I was doing. I still had a few slips in the wrong places though. 

Some photos...

Looks like Jim was able to cold mold over two stringers per side as well as the topside stringer junction.








Finished hull. The Skol featured a self-draining hull. George A, fellow Classic Moth bloggist over at Mid-Atlantic Musings, has also deconstructed a Skol back to a bare hull. Click here to read about his Skol project.




Jim adds the history of the Skol in the comments section which Ive dragged to the main post.

"From what I can make out there seem to have been 4 Skol [models].

Mk 1 may have just been 3 prototypes, which look as if they had unstayed masts and a fair gunwale line.

George A.s boat is a Mk 2. The 1969 Moth yearbook said production was planned for two versions, a SL and regate version. The SL was to have a daggerboard and was the lighter built. The yearbook also says [it sported] an unstayed mast. I think in practice many were built with stayed rigs. They seem to have had false floors and stern tanks, at least some with drains through the stern tank. The actual production detail may have varied, but all had the little extra piece at max beam [hiking winglets].

Mine started life as a Skol Mk 3. She has a fair gunwale line, an open stern and a deck stepped mast. The shrouds were supported by glassed in alloy tubes down to the base of the mast foot.
