    Baffin Bay Skin on Frame Build

    in General Message Board

    Posted

    Frames all cut. The bandsaw is in an unheated building so glad to have all the bandsaw work done.

    I realized that even though the cockpit I had cut out was very close to the Zephyr, it was looking flat without the graceful arch of that cockpit. So I tried to glue some arch into my plywood glue-up. I'll leave it clamped up until tomorrow.

    Here are the pictures from the previous post. I found that if I resized them under 1meg they would load.

    I'm continuing to cut the plywood frames. Soon I will shop for wood for the five long pieces, two gunwales, two chines, and a keel. These can be cut from an 18' piece of clear vertical grain cedar. I'm cheap though and that piece of cedar costs almost $200. I know I can find a piece of spruce framing good enough to make these pieces as I am a builder. It will be stronger, cheaper, and only add about 2 pounds overall.

    After a lot of time spent trolling the internet for ideas I decided to build a Baffin Bay greenland kayak from plans sold by Dave Gentry at http://gentrycustomboats.com/BaffinBay.html. This is a "fuselage" style construction where engineererd plywood frames hold gunwales, chines, and keel in place, eliminating the need for bending, other than a little prebending of the gunwales. My other deviation is strictly for comfort and safety, using a keyhole cockpit and elevating the front deck slightly for more legroom. I will post photos and comments here as construction progresses, and am open to suggestions and questions.

    I decided to start with the cockpit first because modifications I made there would affect other parts of the build. All the plywood parts are from a sheet of 12 mm okoume bs 1088 plywood from http://www.boulterplywood.com/MarinePlywood_4.htm. I roughly copied the dimensions of my Zephyr cockpit which is very comfortable for me. I left a lot of wood in the thigh area which I can later trim back if I want to. I set it up on buckets and boxes and climbed in for a test fit:20171122_150710.jpg.84b241ab17b4fb35fd3b5e8c694e4e8d.jpg20171122_150710.jpg.84b241ab17b4fb35fd3b5e8c694e4e8d.jpg

    I continued cutting frames. I used the band saw as much as possible but some cuts could only be done with a jig saw.20171126_105120.jpg.f0204b308692b2286bbec3a4f60c127c.jpg

    When I had the frames immediately in front of and behind the cockpit cut I set them up for another test fit.20171126_112736.jpg.e944400afb19c54a765081e922eed919.jpg

    I see I'm still having trouble getting pictures to load so I'll try to figure that out.

    Thanks for your replies and to Bill for lots more input via pm. I owned a Chesapeake 17 for a while and while I liked it and would enjoy the woodworking part the fiberglass work is not for me. I've gotten interested in this company, http://www.madekayaks.com/ , they use cnc cross sections for a "fuselage" build. I would like to know if anyone has a boat that would fit me at 6'0" and 175# that would let me try it out.

    For some reason my text is stuck on bold, not intended for emphasis.

    Since I got started carving and using Greenland paddles I have gotten interested in maybe building a skin on frame kayak. I'm wondering if there are any of you who have built or use them who I might talk to, or who might help talking me out of this???

    This is definite, meet at 10:00am, launch when ready. We are planning for about 4 hours on the water with route determined by conditions and group. Messaging seems to have issues so post here if you want to join us.

    Hi Liz, I tried to message you but that function doesn't seem to be working right now. I can do any of those times, We should decide and then see if anyone else wants to join. My phone# is in my profile if you want to figure it out the old fashioned way.

    I cant' believe I've gotten sucked into this.

    These guys can think they have their paddle "locked in" but it's a fact that the only way the paddle doesn't move with respect to the ground under the water is if the boat is moving forward at precisely the same speed as the paddle is moving backwards relative to the boat. These excellent paddlers approach that as the boat nears it's maximum hull speed but the paddle still has to lose position to the ground slightly to compensate for the very minimal resistance on the boat. Without this compensation the boat would slowly grind to a halt like a pendulum if the paddle never went back faster than the boat went forward.

    That was a confusing point for me since I have always understood that there should not be any velocity of the blade.  Isn't the blade to remain stationary with respect to the water and the boat pulled passed it?

    I think that's how we want it to feel but in reality unless the water was in a sense a solid, this is not possible.
