Our trailer has carpeted 2x8 bunks between the front and rear crossbars of the trailer. They flex to match the rocker of the hull perfectly, no point loading, along the lines of Rick's flatbed. I've found a bucket of water on the carpet to lubricate makes off/on much easier. My modifications to this concept is to upgrade from carpeted boards to that new composite decking (I think Timbo used it on his trailer?). They're narrower than a 2x8, will use two side by side with a small gap in between or canted to create a shallow vee. Also adding a 10" vee roller at the rear beam. Those tilting double rollers are nice but sure are pricey.
