Quick lap canoe

[jshoes51]

Haas anyone built one? The files are in the Project Wizard. I'm curious how much one weighs?

Thanks

Jim,
I have built two of them. One as a test out of Luan "doorskins", and one out of marine ply. The finished ply version was about 30 pounds ( I built the 13.5'version).
Ooops, make that three, I forgot about the one I "converted"into a trimaran....

Bill,

That looks great. I might have to make one of them someday.

Any chance you overnighting me one now - we're underwater in my area.

Jim/Tim,
This is really a great way to build a boat! Small "planks" all of which use Bill Young's "step scarf" technology, and they don't use a lot of material.
There's also no need to worry about "engineering" as Bill has located all of the holes for the plastic cable ties which hold everything in place while you lock things together with epoxy glop...
Tim, I still have both lapstrake canoes, as well as one of Karl Stanbuagh's "Scout" kayaks ( also engineered for CNC by Bill Young) on my back patio
just in case....

Thanks Bill. I like the trimaran modification. Is that a lee board on the port side of the canoe I see in that picture? I'm guessing the floats/beam arms are removable?

[billp]

Jim,
Yes it's a lee board, as a centerboard would have been strategically uncomfortable. The amas/akas are removable ( and in this case waaaaaaay overbuilt, being carbon fiber and plywood laminates.I could have gotten by with something about one third of their thickness...). Because of all of the added weight ( bulkheads, deck, 1/2"stainless bolts, amas/akas, etc.) the trimaran weighed in close to 75 pounds making it more of a lap strake semi submersible....

Very cool. I would love to see more pictures of boats built with the shopbot.

John,
Here's a shot of the "Scout"kayak I mentioned above.
For more Bot built boats you can go to Shopbot's web page - http://www.shopbottools.com/boatbuilding.htm
AND this month's Wooden Boat magazine has a feature on Graham Byrnes -
http://www.bandbyachtdesigns.com/index.html
who has been using his Shopbot to design boat kits. This is a shot of one of his 17 foot Core Sound sailboats which I am currently building...

Here's a picture of a Farrier F-22 trimaran I built last year. The whole boat was designed on a computer by trimaran designer Ian Farrier of New Zealand, and he made all the .dxf files available to me. All the forms, interior bulkheads, panels, bunk tops, setees, rudder and centerboard were all cut on my shopbot. This was the first F-22 in the world to hit the water, and he flew all the way to Maine from New Zealand last October just to go for a ride on it.

John, I should also mention that you get the files to build a Tolman Skiff with a shopbot. Forum member Neal Schlee (www.skiffkits.com (http://www.skiffkits.com)) sells them for all Three Tolman models.

Here's a picture of my personal boat, a 20' Tolman Skiff Standard:

Here's a 12' canoe I built earlier in the year. All parts ShopBot cut - 31 I think. Drawn in Rhino. Rhino produced plank shapes too.
