[Rhodes22-list] Oil canning on the trailer

[J Cook]

We just pulled our boat for a little paint-up, fix-up, clean-up time.  

I remember seeing a post, a while back, trouble-shooting oil-canning when the boat is on the trailer. ( Hope I got that definition right.  Where the forward ends of the bunks press against the hull, I am finding a bit of impression on both sides.)

Before putting her on the trailer this time, I moved the winch bracket forward about 2 inches. I also put a drop hitch in the reciever), and the bunks were significantly less angled on the ramp than before..  

We ratcheted the boat up snug, pulled up the ramp, re-snugged, backed down again, re-snugged again and repeated a couple of timed until her bow was well rested against the Y.  But I'm still getting a bit of inward bound to the hull.  

The boat's weight is bearing on the two 128" bunks and one roller at the aft end of the keel.  No weight is on the two runners, which I assume serve only to guid the boat onto the trailer.  There is no front roller on the Trailmaster trailer.  

Any ideas for an easy fix?  I don't recall if anybody has tried lengthening the bunks to 12 feet or instaled a front roller.  I guess those maight be options.  

Hopefully, she's going back in the water soon, so I can get another shot at adjusting the trailer.

Thanks
