Netters, It's been a long time since I built and I do not have a set of plans any more but I seem to remember the original design was for the boat frame to be skinned with 1/8" aircraft plywood and then covered with a thin layer of fiberglass cloth and Ken thought this would make the strongest structure considering all the compression and tinsel pressures from the engine. As long as I knew him (from 1970 to his death) he never had an engine fall off so he must have been right.
