[Rhodes22-list] RC trailer setup

[The Rhodes 22 Email List]

I think some folks maybe over thinking/doing the trailer bunks support issue.  If you look at the lift pictures that someone (sorry, already misplaced who posted) just posted, there were four support points, two forward and two aft.  If you look at the Triad trailer, there are, in reality, 4 support points, where the metal support arms are.  The wooden bunks really are there to guide the boat to the proper position.  Any bunk extension forward of the support arm really isn't helping any.  And a lot of people have reported the hull being deformed by a bunk that is forward of the metal support arm and have suggested lengthening them to spread the load around.  I suggest the opposite, cut it back.  There is a change of curvature of the hull in this area and the wooden bunk isn't flexible enough to follow this change in curvature, which may explain why the bunk is deforming the hull.  Just my two cents.  Oh, and the trailers for all the Rhodes are the same.  The hulls are the same for all of them.  - rob

Graham:  The bunks take the weight.
