    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?

    harbor marine has a decent selection of brackets, was just there and made a note to self about it, it was enough to strike a positive note when I saw the selection.

    I would think the bunks should be spaced to line up with stringers and miss any strakes. I dont know Bertram, maybe you did.

    My boat, the keel support and rollers is only to prevent keel from touching cross bars on trailer loading and unloading.

    Question: Have you looked at the trailer for the Bertram that Darrell runs? Maybe there isn’t one

    I would go with 2x6s for a little flex. your beams provide rigid support and having a second set of rigid support invites wearing of the gel coat as the trailer and boat flex when being towed.

    I would put the inner bunks elevated on swivel brackets that can adjust to the angle of the hull as it sits in the trailer. you have a heavy glass boat and there will be some different line numbers when she sits. with my scow, i had some jacks and boards, lifted the boat a scoche and adjusted my bow supports up to the boat. The center bunks are on swivel bases that can move just enough to provide the most surface contact no matter how she is placed on.

    Don't go for firm exact calculations as the lift operator may not drop it to spec every time.

    And yes, harbor marine in Everett does have a lot of trailer parts.

    I've got some heavy duty bunk brackets from ez loader you can have. They are beastly. They just need a little love. Or you can duplicate them much cheaper that you can buy them.
