   Well, I knew that I would get some negative response to the 
suggestion below. Fair enough. However I would really appreciate an 
expanded  argument regarding the use of high quality plywoods, 
especially if the coamings are finely edged and epoxied. My contention 
is that the existing design of the coamings is flawed in that the 
bending stresses encourage the splitting of the tailing section if 
sideways pressure is inadvertantly applied, which is precisely what has 
happened to mine. I would propose further heresy by attaching the tail 
ends to a cross piece of timber, which would be bolted to the deck area 
immediately behind the rear cockpit, thus protecting the timber from any 
side pressure stress. Perhaps,Tom, you could advise as to whether your 
"Ouch!" is relevant to form or function? Or both, perhaps. If so, I 
would much appreciate further elucidation on the matter. Regards Jonathan.
