I’m trying to fit this trailer to the Bertram using the little info I could obtain about the hull dimensions. Here’s what I mocked up so far. 2 main beams outboard each side. Beams are 6x12 and about 7-1/2ft long each. I cut a 24 degree angle in the top to match the dead rise. I’ll probably cover them in carpet. There is a 16” gap between them for slings. Bolted directly to the axles and frame. They are separate to allow adjustability to avoid strakes and whatnot. The keel support is where I’m struggling. How much keel support should I put in? Does it need front and rear? I have to leave an opening in the front for the front sling. I have mocked up some 4x4s but I’m thinking 2x6 laid flat on an adjustable bracket would be better. Where is a good source for bunk brackets like that? Gonna have it lifted in to adjust the fit but later want to be able to float it on. Think it will work?
