Just had a new road/dolley trailer built by Mike Peasley. Mike makes the bunks adjustable with slots on the bunk brackets. The trailer only has two bunks with four brackets on each bunk. The boat is a lightweight california performance 18' gullwing. I'm concerned about damaging the boat if the bunks are not adjusted correctly. Any suggestions?
Pics? Sounds like too many brackets to have to adjust to contour to such a short boat. I built the trailer for the TX this winter, I built three supports, and it was a pain in the butt to get the 2X6's to contour. You may not be able to use all adjusters.
Hopefully the boat is already rigged. Make sure the hull is sitting where you want it on the bunks. Drop all the brackets to the bottom and keep them loose. Look for the points (L&R) where the hull sits on the bunks firmly and without gaps. Tighten down those brackets. Get a trolley/floor jack and a block of wood. Move to the next closest bracket and jack up the bunk until the gap is gone. Tighten it down. Repeat until you have pulled the bunks up to the hull all the way around. Walk around and double check for gaps and re-adjust as necessary.
This is how I have done it on my trailers.
