about my classified ad:
I have a Jim Howard from Canada who would like to buy the boat. He says he will send me a Cashers check that I can run through my bank and hold the boat untill the check clears..Then he will have someone pick it up..The check will be in US dollars and I have been comunicating by email..I told him According to my bank I will have to wait a Min of 12 working days to a max of 15 working days for the check to clear and he has no problems.
He has not asked to give me more than the asking price and has not asked any additional money be give to the shipper,. Have you heard of any scams comming out of canda? How does this sound , I know This is my decison just wondered if any one had any dealings with Mr Jim Howard of Canada
Thanks Ron Thweatt

May 21-
well Chuck: it took Mr Howard a week to get around to asking me to cash a check WesterUnion send the diffrence of $2600 from the $3900 he was sending me he is so Kind he is giving me $100 Dollars for my "Running around" I am in the south but I do have shoes even if i choose not to put them on - I replied NO NO NO I will not be part of a cash and send program and asked him to not send me any additional emails. The boat is on Trailer sailor and your site. so you could put the word out not the Canadians are after us now! must have been something we said. He goes by Jim Howard will ask for photos about the boat never asking for anything but the lowest selling price as any one would then after about 4to5 emails and you send you address he then lowers the boom about the scam to cash send and pick up of the boat.. Thanks for your imput last week. should have known but all he has at this point is my address no phone nos. and the boat is not at that address
Thanks for the good info

Just wanted to let you know I, for one, am excited to see what comes out of the recent contest for the Puget Sound cruiser! I have longed to have someone design such a boat for me to build. I have lived up here all my life (47 years now). My limited boating experience has shown me that the design problems you listed are accurate and unique to us here; limited beach access, lots of rain, big tide currents, ferries, and cold nights were all there.

Thanks for running the contest! I look forward to seeing the entries; I hope there is a bunch of them.

Best of Boating!

Just having a ball with your Sail Dart Calculator. I'd asked Jim M for the dart layout for Mixer and he couldn't find it so he used your calculator to work out the measurements for me. (I'm guessing you gave him a copy.) His screen shots were not enough but since I've downloaded the later version (I run 2000) I've been able to get all the details.

I've also punched in a few sails I"ve been considering for a smaller boat and have been very impressed with the results.

To give myself a hard copy I've been cutting and pasting the pattern with the layout info via Word. Bit of a pain but very neat results. Would be better if my home printer were colored <g>.

I don't have the higher end math skills to comment but the results look very good to my untrained eye. The last sail I laid out I did the pillow under the sail method. Will have to get the data in Sail Dart Calculator and see how well I did.

Thanks again.

He shows the CE placed forward of the CLR. What? Is that right? I thought I understood this before reading this article and I'm having a hard time wrappng my mind around why the CE should be forward of the CLR.

Michalak's article on sail math suggests lining them up or placing the CE slightly abaft of the CLR (thus inducing slight weather helm).

I just happened to run into the book "The Complete Sailor" by David Seidman over lunch at the library and he says the same thing as Michalak on p94. Haven't had a chance to look at my other books yet.

Wouldn't Nichols placement in the Duckworks article induce lee helm?

I understand this varies somewhat with hull type, but the hull in Nichols' article doesn't look much different than the typical small boats you see around (i.e. it isn't a big deep displacement hull).

Could someone please enlighten me?

Regards,

David Nichols responds:

Having the CE (center of effort) in front of the CLR (center of lateral resistance) is necessary because as the boat heels over, the footprint or the water line of the boat becomes asymmetrical and this causes the boat to want to round up into the wind (weather helm). Imagine the symmetrical, bullet shaped, water line of the upright hull, as the boat heels over and starts to move forward this bullet shape becomes a ‘u’ shape and this ‘u’ shape causes the boat to round up into the wind. Moving the CE (center of effort) of the sail in front of the CLR helps to counter-balance this asymmetry of the hull.

If the hull remains symmetrical as it heels then Mr. Michalak and Mr. Seidman, both knowledgeable men, would be correct in the placement of the CE and CLR. It’s good to remember that the center of effort of the sail and the center of lateral resistance of the boat are really theoretical points and that these points are in a constant state of flux as the boat and sail move through the water and air.

Finding the balance of a sail boat is really just finding the right compromise for these constantly changing forces. Each boat is different and my article was meant to give the builder a starting point to find the best compromise.

I hope this has helped clear up your confusion about this subject. If you would like to read more about this you might check out chapter 4 in Classic Small Craft You Can Build by John Gardner. Dave Gerr has also written about balancing a sail boat in Boatbuilder Magazine, January/ February 1992, and, I believe, in his book The Nature of Boats.

I want to share with you the positive feedback on my Epoxy Ratio Scale article. Thanks for publishing it. Seems I have been sitting on the idea for too long.

Joe,

The scale is absolutely brilliant! I also use System 3 by weight. I use a small digital gram scale. To weigh small batches I zero the scale with the cup on it then pump out whatever hardener I need. Noting the weight I multiply that by 2.33 to get the resin weight and add that number to the original hardener number to get the total number needed. Now its simple to drizzle the resin in until the scale reads the right amount. Pretty hard to mess up but limited by the 100 gram max of the scale. I have an old triple beam scale that I was thinking about using for bigger batches but your idea is just too simple and elegant to not use it. I'll build one tomorrow.

Thanks for sending the article to Duckworks.

What a great idea !

I use West System epoxy with the graduated pumps.
I'm on my third gallon
building the Payson / Bolger Bobcat. The problem I had was with an older set of mixing pumps that I had had for a couple of years. I noticed I was getting low on hardner but still had more resin than I thought I should have. I checked the pump and sure enough, the little restrictor plate in the hardner pump was partially collapsed which meant my ratio had been slightly off. I don't think it seriously affected the finished product, but I knew I wasn't getting the exact ratio for the first half of my resin. I went and bought a new set of pumps, but there are a lot of times when I need less than a full measure from the pumps. When I needed a small amount I would always have try to find some other use for the remainder of my small batch.

Epoxy is so expensive I hate wasting even small amounts. Your scale idea seems to be a near perfect solution. I'll build one this weekend and give it a try. I'll let you know how it works.

Thanks for a great idea.

Hi Joe,

Just wanted to let you know I built a scale to your idea a few nights ago and have had a couple days use of it. It is great! I love it. I have been building my own boats with epoxy since 1970 and have been through maybe 150 gallons of the stuff. I've used the Gougeon expensive pump for a big project, but have been using System 3 the last 10 years or so with small pumps and graduated cups. Your scale has all the other cheap methods beat, and is just about as good as an expensive pump and doesn't need to be cleaned. I'm cheap too.

I made the board 20" long which allowed for a ratio of 100 to 44 using 25 quarter inches (6 1/4") for the first line and 11 more ( 2 3/4") to the second line. I used two little angle brackets instead of the bent metal and teko nails for pivots. Took about 20 minutes to build with stuff I had laying around. I feel like I beat the system at last and love being able to mix more varied batch sizes than I have been doing with my marked cups, and more accurately too. My present project is "Bufflehead" a 19' row/sail cruiser .The first installment is in Duckworks March letters, and the second one in Chuck's hands. Hope to have it in the water in June. Well, gotta go mix a batch and spread some goo now.

Thanks for sharing.

There are two things that I seek. Does anyone know where there are available the original West Wight Potter plans for home construction in plywood (15 or 19 foot)? These are probably in England somewhere. It is also my understanding that, in the misty past, the original Sunfish was designed to be built in plywood. Does anyone know where those original drawings are?

Next is any help in finding effective fabric treatments for rot proofing cotton sails. I can find and sew heavy cotton OK, but how to treat them? Heck, dacron is getting too expensive and cotton was good enough for 300+ years, right?

If anyone has any information, please write me at [email protected]

Hi folks, I just had to write about Gary Lepaks' idea and construction of Bufflehead. For about two years I've been looking for a simple vessel that could be used by one or two people for cruising and camping in shallow water for a few days. I wanted a boat that gave a little privacy for a small toilet and offered room to sleep without your feeling like you were in a coffin. Some really beautiful paradise is still out there if you can sail,row,paddle or pole in water 12" or less.

In my situation some basic considerations are mandatory. My first mate would sail off the edge of a flat earth with me but not without a convenience that had a roof! And so the search went on. Many designs use more weight in ballast than we would carry for all our provisions (toilet,cooler,stuff) and I wanted to tow as light as possible and be able to store inside an already crowded garage (boat investment will last much longer). Apparently I'm not alone in this design quest as the theme surfaces again and again in the chat groups I follow. Maybe simplicity and minimalism is the core of this
home boatbuilder thing. I'd like to encourage Gary Lepak to
keep the details coming on a very, very interesting boat.
Yours, Robert Jolly

Chuck, hola....

I am a new suscriber, well, some months now... Long tine fan of MAIB, and wish I could read your's in the tub in the morning. alas.... (We met in Sept. at Lake Powell, the Gale family-"the mud kids", Heather with her whitehall and my pulling skiff.) re. latex paints....

Tom, my son in law, has painted parts of topsides. not coated w/epoxy w latex and it did not last thru the winter. (nasty) Also the ply suffered mightily.

I have limited knowlege of durability of latex, only having used it on house projects, but have found it does not hold up without a very good interface between it and the wood, ie, epoxy or a quality primer, ie, oil based or epoxy primer.

I highly reccomend System 3's water based primer, pricey, slow curing, but incredibly tough stuff.

Is the word fillet when used in boatbuilding pronounced as the same as 'fillet mignon' or as in metalworking 'fill it' weld?

They then continued along the coast to Mexico where they were held up for some months and one son went home but the father and other son paddled on along the coast and into South America eventually reaching the mouth of the Amazon. The entire trip was done under their own power, no hitchting rides on motor vehicles.

In my opinion the judges greatly understimated the capability of narrow boats.

You and I have a common goal, we have both seen the many debates on which sail rig is better than the other, most of which is pure speculation or quotes from one of Czeslaw Marchaj's books where he reports on his numerous wind tunnel experiments on various rigs.

The gimbal test rig you suggest is very intriguing. I wanted to share a dream of a sail rig testing apparatus that is along the same lines, possibly it could be called a poor man's wind tunnel. What I envisioned is that some block of wood is suspended from a string, it's sole purpose is to hold a model sail rig and trim the main sheet to a certain angle. Then a fan blows down on the sail rig, which should produce lift. To evaluate the rig's lift, a counterweight is suspended on the other side of the string and the weight is adjusted until the rig does not rise or fall. Some sort of rail or slide might have to be added to keep the hull from sliding around on the board.

But in the end, the reason this test rig stays on "the list" instead of actually being built is because I built a PDRacer which is the ultimate test machine, all the hulls are alike with only the sail rigs being different. To make a new full sized sail rig, it only takes me about an hour plus a $9 sheet of polytarp. First one across the finish line has bragging rights to the best sail rig.

Great idea, fella! Just a quick note that the Boston Public Library has a pretty awesome collection of old boat stuff too, but some is in pretty ratty condition (probably from much use over the years).

Hi Chuck

I just finished reading Patrica Lesh "Launchitis"

What a great read, very entertaining, She has no email so I am voicing through you. I will have a very different look at people launching the next time out. Should be less than 2 months. (winter, bahh) .
I have never noticed this in people. I don't think I have it, however the fact that I don't see the others around me during this event makes me think that I might. I am fortunate to be one of these who gets the boat in under 2 mins. But getting it out is a whole different story.

Keep up the great site.

• love ‘em – I vote to keep them. - Rick Malagodi
• Great idea to put movies up! I'd rather see them in .mpg or .wmv formats though so they can run on windows media player. My two cents worth. - Doug
• Loved the sailing clips. Keep up the good work New Stuff is Great.. RP
• Keep them coming. You get a much better sense of the boat in a movie. - Reed Smith
• I like the idea very much. Don't you have a "rowing Mixer" movie from Thomas? I would love to see it. - Wojtek
• I like the video clips, they're easy to watch. Here at work the download is no problem at all. I'll try 'em at home in a couple days on dialup. I don't get to see homebuilt boats in action very much, and I can't see mine from across the water when I'm in it either. I'm going to have to get a video of Trixie B in action. - Jerry Church
• Yeah! Lot’s of fun if it doesn’t suck up to much bandwidth for you. I think it’s great to be able to see home built’s in action! - David Farr
• The video clips are a great idea, and the around 1 MB size has pretty good download time and resolution (this on DSL 768 downstream, 256 up). Pictures are worth a thousand words, they say, and the video provides a more dynamic understanding of what is happening. - Matt Meacham
• I love the video clip idea. We recently installed DSL, and so have the bandwidth to enjoy these. There isn't a lot of sailboats around my neck of the woods, and so it is really instructive to see someone else sailing. - Dave Hahn

Greetings! I am the president of a Non-profit Medieval Recreation group and we are trying to plan a project to build a replica Viking Longship at 2/3 scale (about 40 foot at the waterline and 6 foot at the beam). We are looking for sponsors for the project (we are the appropriate non-profit type so donations would be tax deductable) but we are also looking for technical advice as well. We have several very skilled carpenters, but no shipwrights per se.

The Shire of Glenn Linn is in Upstate NY, on the sunny shores of Lake George. Our borders encompass the Southern end of Lake Champlain as well. Specifically we're in Glens Falls, but the boat will most likely be built in Lake George. Many of the components (ribs, fittings, etc) can be made here in my shop and assembled on-site, but we're planning and determining resources right now.

The ultimate goal is to build her and sail all along the two lakes (George and Champlain) and the canal system, marauding as we go, and building public awareness of Middle-Ages ship building and culture. Our first campaign would be to "take" Fort William Henry and then Fort Ticonderoga on Lake George.

Yaaa-Hooo!!!

10 minutes of the 'I won Boogie' later…: You know, I've been on pins and needles for at least 3 weeks now. I want to thank the judges for their time and efforts in what must have been a very difficult deliberation process.

Right now I'm a little speechless so I'll compose a suitable letter of thank you and comment later.

Steve Lewis (back to the boogie)

It was good to see the sprit sails and the over-the-mast crab claw sail. It was sad to learn there is not enough wind on the lower Mississippi for the trip. There are four sailing clubs on the Ottawa River in the city of Ottawa, one across the river in Quebec, and others close by on the Gatineau and Madawaska Rivers.

I do most of my small boat sailing on the Rideau River. All of these rivers are considerably smaller than the mighty Mississippi.
There's plenty of wind on all these waters from spring break up to winter freeze up. Lake and river winds require different tactics and make for hours and hours of fascinating, never boring, sailing, in my opinion. We have boats sail up from Montreal every summer. It was interesting to read that a third of the time there is not enough wind on the lower Mississippi to because in this area about a third of the time there is too much wind. I can imagine there would be no sailing clubs on the lower Mississippi where the current makes it only possible to sail downstream. The lack of wind is a shame because on a trip downriver prevailing westerlies would put a sailboat on a fast reach most of the time. As high pressure systems moved through the wind aft would be ideal for a spinnaker.

I think it was a a bit unfair for the judges to base their decision on a personal preference for fat boats over thin boats.
Trips on wilderness rivers are in thin boats, if you ignore inflatable rafts which are sometimes used. Thousands of people do these trips every year. Hundreds come back year after year. I'd find sitting for hours and days on end in a fat power boat excrutiatingly boring.

The only real objection I have to this year's judging is one sexist comment that a woman would not be willing to make a trip in anything but a fat motor boat. I'd invite that judge to come up here and try competing against our local women sailors, and to take a wilderness canoe trip during which he would quite likely be struggling to keep up with woman trip members and woman guides.

I have to mention one amusing thing I saw which was the contestant who budgeted $26 a day for food. Some people claim there are no differences between Canadians and Americans but diet would have to be one.

I hope the Duckworks design contests continue to provide novel ideas, great entertainment, and interesting differences of opinion.

Chuck,

Can you or your readers shed light on this situation?

I was looking into getting a couple additional genoa lead cars for my 22' Capri. You don't need to know what they are, or why I wanted them, for what follows, however.

I looked up the parts in the usual catalogs - West Marine, Defender, etc. They have lead cars from Harken, Lewmar and Sheaefer starting from about $130.
That seemed pretty high. The cars I have do not have a manufacturer's name for part number on them anywhere.

I called a Capri dealer. She did not have lead cars in stock, but suggested I call CatalinaDirect. (That's a company; she did not mean to place a direct call to Catalina Yachts.) I've dealt with CatalinaDirect before and found them knowledgeable and helpful. They have a couple of choices of lead car at $37 and $47.

The point of the story, and the connection to Duckworks, is that there are companies out there making marine hardware that is suitable for smaller boats that is much cheaper than the stuff made by the big name companies for fancy racing boats, and the cheap stuff is not getting into the catalogs of the big distributors. I'm sure these are exactly the products you want to feature in the Duckworks store, but how do you find out about them?

Well .....I figured I'd let ya'll know that I'm out of the shop now and do'n pretty damn good! Chrissie has taken excellent care of me...you know...making sure I don't do anything stupid and break something else. Yep...them 5 by-passes was enough repair work for a while, and I ain't in no hurry to go back into the shop to git fixed. Got a good report from doc today and should be released on Feb 21st and will be totally released in about the end of March. We are both anxious to get back into the water and out and about in the Teardrop. later

I am thinking about entering an outboard race here in New Zealand that is dedicated to Seagull engines that are only 4.5hp. These engines were designed as barge pushers. Do you have anything that you could recommend in your range that might be suitable. It needs to be light and hopefuly able to get on the plan. The only limit I am aware of is 3.5:1 ratio. I am guessing making the bottom out of 1/4" and sides of 1/8"

Look forward to your suggestions

Hi,

With reference to the banner advertisement at the top of the front page of your online magazine. (ad appears above - Ed.)

John has designed some marvellous boats over the years here in New Zealand, but I can assure you that even he cannot conjure up crocodiles on Wellington's windy coast.

Try changing the word crocodiles for "seals" maybe or "dolphins" ?
But hey, if I didnt enjoy visiting your site, I would never have noticed.

Tell Shorty the real name of the tool in his new article is a "marking gauge". And tell him to look at the messabout calendar! He's the kind of guy who would know of some other stuff.

Thanks,

Shorty replies:

WOOOO HOOO!!!! Didn't have enough space or an economical way to transport the holder out here in Phoenix, so I sold her back in Houston. She was bought by a guy from Austin, I told him all about the Duckworks messabout etc. so you might see her again.

I bought a bare laser 2 hull out here as a replacement boat, so starting from scratch again. The hull is in good shape with no holes, but I want to convert it into an unstayed mast, so will do an article about that. Probably not for another year though, am building another pdracer and need to finish the oday first.

I bought a trailer, the laser 2 and a Melges M16 scow all as part of a package deal, am selling off the M16:

You need only two tools: WD-40 and Duct Tape. If it doesn't move and it should, use WD-40. If it moves and shouldn't, use the duct tape.

However, I think he does not see where George Buehler is coming from. George is used to being out in "survival" storms, in large, heavy boats. The stresses involved are enormous, and George anticipates them by building low stress, heavily built vessels, such as those popular in Northern Europe. The idea of a laminate failure "out there" is not acceptable to him. Let's face it - under even ideal conditions, haven't you had some bonding that was less than perfect? Isn't the bond limited to the top layer of plywood? I often use a construction knife to score any surface to be bonded and still occasionally have problems.

I guess it's best to conclude with the comment that "different stokes for different folks".
Bob Patterson

Have seen this idea float around the net, what the concept is that you fly in somewhere, have relatives pick you up at the airport, then you pickup whatever materials you need at Home Depot, and build a boat in your relative's back yard in one or two days, and take them sailing.

Some of the limits might include the amount of tools you can take with you on the airplane, the airlines have a strict limit of 50 lbs per checked in bag, and some only let you take 2, so one bag for tools & supplies, and one bag for clothes. Not sure what the limit on spending for materials should be, the boat will be left with your relative, or possibly left at the lake / beach.

One requirement might be to supply a building key showing exactly what gets done, in what order. To show building sessions and prove that you can build it in 2 days, even with glue drying, paint drying etc.

Judging could be:
most durable looking
best big water capability
simplest and easiest
most likely to fall apart on first use
overall most plausible

I hope they will manage and negotiate nonviolent solution. In case of large bloody clash leading to collapse of Ukrainian democracy we would have a problem of refugees but would not be engaged in a military conflict.

I have to tell you that there is another aspect of the problem. One of my dreams is to sail from Warsaw to the Black Sea along Polish and Ukrainian rivers. I would miss free Ukraine because of this reason, too.

If you review a good cross section of his designs, you realize that he is a master, having done some of everything, from his plywood "box boats" to a replica sailing ship, that was destined, years later, to star in the recent movie "Master and Commander". And so "Brick" was presented a a simple, easily made, commodious, "boy's boat" (a historical reference - no sexism intended). I kept looking and looking at it. Simple, pleasing to the eye and easily handling my mid-aged girth and weight. And yet…… admittedly a bit flimsy as specified, short waterline length, big bellied so as to be apt to bog down in self-created waves (these comments from the designer in his book "Boats with an Open Mind", which even included a 20 Foot big daddy version - "SuperBrick").

C/M/U was conceived to be the big brother to "Brick". In standard construction specifications, C/M/U stands for Concrete Masonry Unit (ie. cinder block), so as to keep the masonry cliché going. Enlarging the station intervals by 25 percent, slightly reducing the already generous freeboard, doubling up the mid-section of the gunwales, retaining beam at about 4 feet, slightly playing with the bow angles for looks, using doubled up ¼ inch plywood for the bottom planking, with heavily built bow and stern transoms, adding bow and stern decks and a standing lug rig. . Just as Phil mentioned in his book, I now have a much different boat - heavy (150 lbs.), more difficult to construct (had to put framing under those decks), and definitely a handful to load into the pick-up truck.. But I love the looks and it suits a 6 ft. 2 inch, 270 lbs. guy like me. A 21st century "stealth" Beetle Cat, perhaps? We shall see. Too cold to take or send pics now. Hope to have sailing report this summer.
