Cool!!
Will the ends be square punt style or foam 'pointy ends'?
Covering with canvas?

Punt style. The design is a Flats Rat boat. I am planning to add a mast and leeboard so I can have the option of paddling or sailing.

Have another boat but too heavy to bring along when we camp. I am hoping for a weight of 40 lbs or less.

Ran into to a problem with the foamey yak. Glued canvas to foam. Next Morning the sides held firm but the canvas on the bottom was bubbling.

Went to lowes and found a sheet of 1/16" x 4'x8' pvc. Used loctite power grab to adhere pvc to canvas. Time will tell if it the right solution.

What kind of glue did you use for foam to canvas....?

[clermont cubby]

I used TB II. Picture below of my solution.

CC, that should really protect the bottom ...

GPW:

I was pleased to be able to discover the pvc sheets. Was familar with FRP and used it as a ceiling material for our TD Cubby, but I believe the PVC will make a better cladding on the bottom. After building the hybrid foamey Puddle Duck sailboat last year, wanted to try a smaller lighter boat (single sailor) that could be easily transported on top of the teardrop.

Should have the boat painted and float tested next week. Later, install sail rigging.

PVC is pretty Tough stuff , can’t wait to see your sail rig ...

PVC will be great for dragging it on the beach. I built a 9' punt a few years ago and one of the changes I want to make is to replace the bottom runners with plastic, at least at the front where it hits the beach.

You guys seen this ??? Since I can get 10’ blocks of foam ...

That is so cool. Foamey carved yak. I was hooked on foam boats since the first time I saw a snark sailboat as a kid.

I should have it in the water ( as a yak) next week. Need to work on the sailing rigging afterwards.

This boat will be light enough to carry on the back of my hitch cargo carrier on the Class B.

It's a surf kayak.

Ton’ , we have No Surf !!!
Seriously , when we were helping the paddleboarders make their boards, we couldn’t help thinking about how easy it would be to make a Foamie “sit on top” Yak for the local lakes and bayous (Fishing) ...
Those were 12’+ boards ... very Light !!

Those "surf" kayaks are designed for whitewater and the like but are not very directionally stable. They are designed to be maneuvered. The paddleboard is meant to go straight and though you can certainly surf it, it is not meant for whitewater kayaking. Except for the facts that they are meant to float and designed for one, they are almost totally different watercraft. Hmmmm, back to the whitewater kayak. One billet, a bit of carving. How to keep the wall thickness even???? Will want a fairly rugged outside shell. You should expect to bounce off of rocks while doing whitewater kayaking.... Maybe selective reinforcement.
