I made it over a decade and a half ago now. It's a "retrieval boat" type that was used in the arctic when they switched to guns. You hunt water edges and would have to retrieve whatever you shot before it sank into the water.
It's a sewn-on ballistic nylon skin coated with water based polyurethane over a frame made of Sitka spruce and cedar. It's quite light at about 29 lbs. The length is 9' 9" with a 25" beam.
It is easily carried by the Paradox pack by planting its center of gravity in the middle of the frame
