I think my transom is flat on my Master Angler and this would spread the clamping effect. Or do the clamps provide for good adhesion ? Also would it matter that i will be using composite ?

Yea, I had a pair of 2x6's that I was going to put behind the clamps to spread the load out a bit more but it is difficult to do this with out some extra hands or help. I wasn't able to get them behind all four clamps at the same time while holding them up off the top lip of the skin. If I would of had some one there to help me I probably would of added them to the back side of the skin but I don't think it really needed it anyway. The core was two 3/4" plys and had almost a 1/4" of woven glass between them and I also soaked the wood well with thinned resin plus added a layer of thick mat around the core. It was so stiff prier to installing I don't think the inside needed boards for more support at all. On the outside it might of helped some but the skin was very thick as well and looking down it I did not see where the 4" square blocks I used bowed it in any. I took a straight edge down the back side once it sat up and it looked even all the way down the back. I try not to put too much pressure on the core due to it will squeeze all the epoxy out of the joint. But the more even you can add pressure to it the better off you are that is for sure.
