Rick has an interesting idea with a carpeted flat bed trailer. Why would this arrangement create more damage to the bottom of the hulls than that with cradles or rollers? On a flat bed trailer the boat weight is evenly distibuted over a larger area as opposed to cradles or rollers.
In the near future I will upgrade my galvanized trailer to cradles or possibly to another configuration. I was considering purchasing recycled plastic decking boards (2'x8' if available) and bolting them to the trailer crossbeams so that the boards run under the hulls length wise. The boards could be covered with marine carpet. I could even make a lip an the outer part of the boards to limit side movement. Any comments?
This is exactly what our H20 hulls are riding on, 2x8's with a close nap carpet. Basic standard cat trailer without rollers or cradles. As far as rocker goes, not much to a H20 but the exterior grade wood flexes enough to match the curve. The carpet remaining wet I don't see as much of an issue. The trailer has simple, non-tapered, 10 inch, vertical rollers, on the INSIDE, at four points, attaching at the crossbars (bottom) and an "arm" to support from the sail box at the top leaving a 1" gap between rollers and hulls. These are guides for loading, do not support any load, and also prevent side movement (don't recommend flying a hull with boat on trailer <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />).
