My most rewarding project to date. Living in Michigan, if you don’t have a boat, you’ve probably wanted a boat at one time in your life. I love wooden boats and think they are the ultimate in form meeting function, beauty meeting purpose.

I plan to build the full size version, 15 foot sailing/rowing boat in the next year or two. Having experience only in building non-sea worthy rectilinear objects, I thought it’d be a good idea to build a scale model to learn the curvilinear techniques required in boat building. And the lapstrake style of building a boat where precisely laid out planks (strakes) are cut and fitted into each place to form a rigid shell of the boat. Internal ribbing is the added, seats and other inboard fittings are fabricated and installed and viola’.... a boat!

I enjoyed this project immensely and the learning experience was fantastic. This 5 foot model now hangs from the ceiling of my sister-in-laws log home. It is constructed of 1/8” luann and pine. Each plank or strake is held in place with nothing but good ol’ Titebond II. Painted surfaces are Rustoleum’s Painter’s Touch. So this boat would not last long in the water.

I am planning to build another 5 foot model to improve my skills. When completed, I plan to make it the centerpiece of a coffee table by fabricating a wooden cradle that will hold the boat and support a glass table top directly above it. Should make for a unique and beautiful coffee table.

Then, the full size 15 footer and I will finally be a “boat owner”!

IF you want another scale model – then build it. As a builder of a few wood kayaks, I think you are good to go for the full size model!

Thanks sras. I’d love to start the full size but I just can’t afford it right now. I can afford another model and the full size will benefit from my extra practice. And I need a coffee table too.

My my, that is so cool. Nice job and good for you.

I (a landlubber) was under the assumption that Lapstrake meant that the strakes were held together with lap joints, where each strake overlapped the one below it by a half inch or so. This would not result in a smooth side, but rather looked like individual ribs. But I guess they could be smoothed. I need to study more.

Anyway, that is a nice looking boat,
Steve

Awesome build. I don’t think you need more practice, but the coffee table idea sounds really cool. Great work.

I like it…......... I have aways want to try my hand at boat building also. I just don’t have room for a full size, so maybe you have given me ideas… LOL .

First of all thats one beautiful boat, well done. Secondly it reminds me of a conversation that I overheard in the early 60’s while serving in the U S Coast Guard. A gnarled old Chief Bos’n’s mate with 27 years service was getting ready to retire when a new seaman ask him where he planned on settlling down. The old Chief looked at him and said son I’m gonna find me a small row boat and strap it to my back and then start walking inland. When I get to a place where someone comes up to me and asks “whats that on your back”, I found my new home. I think the moral to the story was the Chief was tired of the seafaring life.

Very nice, I appreciate your craftsmanship. I plan on builing one in about 10 years.
Thanks

Thanks everyone for the supportive comments. I appreciate them.

RetiredCoastie.. the boat is a one-off of the Walter Simmons designed Christmas Wherry that he markets at www.duck-trap.com/dtw.html It is one off because I couldn’t afford the plans so I found everything bit of info published about the boat, traced shapes in Google SketchUp and filled in the missing info to get a resemblance of Simmons BEAUTIFUL Christmas Wherry. Check it out, it is lovely. Obviously the published plans and loftings will be in hand before I begin the full size.

SPalm… you are correct about lapstrake. The strakes or planks do indeed lap over the lower strake. That doubling of material at the lap is the secret behind the design. The lap create virtual stringers that make a very light weight and strong structure. The frames (sawn ribs) provide additional stiffening and strength. You are correct that the result is lots of ridges. The main photo does not revel these only because of the lighting. If you look at one of the photos that is yellow tinged you’ll clearly see the ridges caused by the overlaps.

Great work Frank. You’re right the boat does have beautiful lines. I think your idea to build a model was good. Even though you can’t afford the the full scale yet, you are still working towards it. Judging from the results of the (big) model, I’m certain you will be building a fantastic boat at full scale. How did you get the frames to the correct shape and also manage to place the notches for the strakes so accurately?

Thank you stefang. To get the frames notched correctly I made templates for each one individually. I did this using cardboard squares that were slightly wider than each strake so that they’d overlap on top of the previous strake. I placed the corner of a square into each corner of a lap and tape it to the next one etc… resulting in a “chain” of cardboard squares that was a close pattern of the angles and distances of each strake over lap or “land” as they are called. I used that pattern to trace onto the frame blank. Then drew an arc on the inboard side of frame that was pleasing to the eye. I still had to finesse the notches of the frames a bit and they weren’t all perfect but, a little caulk and paint makes them look perfect. :) Actually this is one of the skills I want to improve before the full size boat since these frames are an important structural member and you want them to have full contact with each strake.

Great job. I have been planning a 1/2 scale “Trappers” strip built for some time now. Like yours mine will hang in our log home.

Thanks for the explanation Frank. I’m looking forward to seeing that “Boffee table” when it’s finished. A great and unusual idea.

Great idea. A wooden boat is on my “to do” list too. Looks like yours was rewarding and continuing to be enjoyed. I just may have to try the scaled down model. Thanks for the inspiration.
