I built this board back in the winter of 2010-2011, it is shaped from a single block of EPS (styrofoam) with glassed on twin wooden fins. This was an attempt to make a board that would be good in small mushy waves which we tend to get a lot on the East coast, it was 6' by 22" wide. I think at the thickest point it was 3" with extra thick rails all around, I thought that the extra thick rails would be good for getting into waves faster and while that holds true what I notice is that the board did not turn very well and it surfed more like a big body board, possibly because it was a twin fin. Over all it was fun to try and it definitely was easy to paddle since the board floated so well and I kept the rocker flat.
The board was painted directly on the hotcoat and glossed over with a coat of resin, the end result was very nice visually. I think the paint I used was a water based acrylic from the hardware store. The glassing schedule was strong, double 6oz on the deck and single 6oz on the bottom. The board was stringerless since it was so thick I was able to get away with it. Fins were shaped from a piece of cedar fence board, I free hand the shape of the fin. Epoxy used was Resin Research and additive F was used as well, FYI additive F is a wetting/surfacing agent that eliminates blush, increases hardness so epoxy is easier to sand and what I really love about it, is it helps prevent fish eyes! I think it's mostly xylene, which is I'm sure something that is not good for you, I always wear a respirator and gloves when working with epoxy and xylene. Even tho epoxy is low VOC, I'm not taking any chances, also epoxy is a skin sensitizer, meaning cumulative exposure could make some people allergic to it.
I have since sold the board and the current owner was very happy with it.
Dimensions from what I can remember is 6' long, 22" wide and 3 inches thick.
