There are several places that I would like to access that are difficult to get a regular kayak into.
I have been looking at a Skin On Frame design that would be 12 feet long weigh about 15 lbs. Carbon fiber stringers and aircraft plywood.
But recently I had another thought entirely. SUP, 10 foot long and 32" wide.
Catamaran configuration with wood stringers down the inner edges of the hulls and no skeg.
Would not need a handle, just carry it by the hull.
Of course graphite epoxy bottom for toughness.
Hybrid Kevlar/Carbon deck for the toughness for standing and gear.
Some kind of seat for double paddling. Probably up off the deck to keep the bottom dry, prevent monkey butt.
Maybe a handlebar?
Padeyes and fittings for tie downs, for a cooler and gear. Padeyes mounted on small pieces of wood.
Rod holders like the Railblaza.
Thought I'd use 2 inch thick pink Styrofoam sheet (1.4 lbs density) for the core. Would provide over 300 lbs of flotation.
White epoxy on top to keep it cool.
Basic planform layout
Bonding the "hulls" to the board and adding rocker.
Bent it an inch and half then bonded, expecting springback. Which it did. Got about 3/4" of rocker.
