I'm new to the kiteboarding scene ,although I've windsurfed for years.All the postings have inspired me to try my hand at building some .
My boards are two 3/16 plywood laminated with epoxy paint . The rocker and concave was achieved by laying 1"and 2" blocks on a workbench where needed and clamping and screwing the boards together.One board has a layer of fiber glass on the bottom one has the layer on top and one has it in the middle.The others don't have any glass.My footstrap anchors are stainless nuts spot welded to 1/16" stainless and the straps are old backpack clips, the other one is seat belt material. The fins are formed from belt sanding blocks of nylon.
The paint is colour shifting which is really cool.Now I just have to wait for the warm weather to see how they work and hold up.
