Built this Skin On Frame kayak for my wife’s Christmas present this year, also built a paddle and will get that posted eventually. This is a Kudzu Craft Curlew design, 15’ over-all length. I bought the book and lofted the frames myself.

The frames are made from Baltic Birch plywood and the stringers, keel and gunwales are Western Red Cedar. The coaming is a laminated build using Mahogany.

The whole thing gets lashed together with artificial sinew and then the fabric is stitched over the frame and heat-shrunk. I used 12oz polyester and then painted it with Rustoleum oil-based paint. Takes 3-4 coats to get the fabrics and seams as water-proof as possible.

I enjoyed building this boat because it went together quickly and easily and each step was different and kept me engaged in the project from start to finish. Took about 40 hours total to get it finished.

Excellent! Built 10 of these with my Boy Scouts back in 2001. 40 hours that’s pretty fast work we figured out to be in the 100 hour range, that’s with unskilled BS labor. Those frames look so elegant before covering and you kind of hater to put the cover on. Maybe we’ll meet on some of the western New York waters next summer. Have fun and enjoy.

Very nice kayak. Looks a lot more stable than mine. Boat building is addictive.

In light of what tyvekboy said I stole this from eHow to give you an idea on how to size or resize a kayak. I too had a stability problem with the second one I built. It tracked straight, paddled pretty good, (I could have used a slicker skin material), but it was like riding a knife edge to try and stay vertical. I had read this info somewhere else in the past and was lucky to find it on eNow. After I had paddled mine a few times I guessed at what it needed then found this info and my guessing was pretty close to what is mentioned here so these measurements do work.

Things You’ll Need
The following archaic body measurements are used when determining proper kayak sizing:
One fathom = the span of your outstretched arms from fingertip to fingertip.
One fist width = the width of your clenched fist.

Sizing the Kayak

1 Measure your fathom length. The length of a kayak should be three fathoms. So, for a person who’s wingspan is 5 feet, 6 inches the ideal kayak length would be 16 feet, 6 inches. The length is related to your reach. The longer your reach the more leverage you have, which translates into needing a longer boat for proper balance.

2 Measure your hip width. The beam, or width, of the kayak should be the width of your hips plus two fist widths. An easy way to measure this is to sit on a floor, put one fist on each side of your hips and mark the outside edges. This is the optimal width for your kayak.

3 Measure the length of your fistmele—the fist in the thumbs-up position. This is the proper height for the inside of the hull. This height assures that you can lay your head or shoulders against the deck behind you in order to get your center of gravity as close as possible to the water line in the event you need to roll the kayak.

4 Measure one of your feet. The small of your back should set one foot length back from the geometric center of the kayak. This determines where the force of the paddler will be transferred to the kayak.

Tips & Warnings
All of these measurements can be adjusted. For a more stable kayak, increase the width from two to four fist widths. If you want a faster kayak you can make it narrower. Remember that making the kayak shorter increases maneuverability at the expense of speed and stability. Increasing width increases primary stability at the expense of speed, tracking, and maneuverability. The reason many advanced kayakers build their own kayaks is to be able to adjust these dimensions to fit their own personal preferences. If you are sizing a pre-built kayak, try and find a boat close to these sizing dimensions and see how it feels, then try other dimensions to find the feel you like.

Yeah, next few :) My wife wants to get into kayaking and this one is hers, I plan to build one for me and then a couple of kids ones for our 5 and 7 year old boys and mount some temporary outriggers on them if they need the extra stability.

I will wait until after they see her using this one before they decide they want them too.

Well Rich then my measurements should help in sizing kayaks for your boys. You are beginning to remind me of one of my Boy Scout families that built one of the kayaks years ago, once they had the one homemade one they got heavily into kayaking buying high end kayaks for everyone and all the gear to go with them, wet suits/ dry suits included. And they blame me HeHeHe! Hey it’s great fun building and a great sport to get into.
