Brain,
They don't need to be exactly formed as the boat weight will force them to take proper shape.  But they do need to be bent so that there is enough slack in the boards so they can take the correct shape.  There is a little play where the boards attach to the frame.  I measured the distance from the holes on my old bunks and made sure the distance between the holes on my new bunks were the same. - rob

Subject: [Rhodes22-list] Trailer Bunk pre-stretching

I'm replacing my two hull support bunks on my trailer.  Do they need to be
pre-curved before putting the boat on or will dunking the trailer and
putting a wet boat on them force them to take shape?

I saw a post where the owner used ratchet straps to create the curve and
other posts where it said it wasn't necessary.

Has anyone ever used a router to take a corner off the keel boards to
prevent the keel from sitting on top when recovering?
