I second what Charles said.

I replaced the bunks on my Traid last year and can confirm after bolting
the straight boards on the trailer and setting the boat back on it, there
is enough room in the slotted holes to let the bunks follow the curve of
the hull. When the boat is launched the boards go back to being mostly
straight again.
