Kayak fishing the Lone Star State...

Now that STRIPER2 is pretty much fully functional, I thought I might start another project.
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.

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.

cant wait to see what you come up with... ive loved all your builds and am currently in the process of brainstorming up a catamaran style SUP myself.

Blank roughed out.

08/12/17 After doing a bunch of shaping yesterday, weighed the core this morning. A disappointing 9 lbs. I had calculated something less than 7 lbs. Glass should come in at around 6 lbs, so still should be able to reach the goal of carry with one hand though.

0814/17 A little touch up sanding and then mixed some epoxy and microballoons. Filled the divots and then filleted the inside corner and glassed the tunnel between the hulls. This allows me to keep the sharp edge on the inside bottom corner of the hulls where the wood stringer will go.
