I have an old style sail box (coffin style) and am now looking to mount it onto my trailer, which is a Trailex for a H16. (A good picture is at http://www.castlecraft.com/large_catamaran_trailers.htm
It is the first picture, the TX-416.)
The trailer cross-bars are about 74" apart with not much room in front of the front cross bar. The box is about 134" long.
I am concerned about mounting it on the cross bars and have 60" of box hanging out the back. The other option is to mount it between the front diagonal and the rear crossbar, but the diagonal is on a different plane, ie. the box would have to be slanted unevenly unless i wedge it.
Does anyone have any sage advice regarding this?
