I have intended to write an article about trailers. The crux of it all is simply make a flatbed trailer.
I have several trailers, mostly Trailex. I started off with a Hobie 18, Nacra 5.5, Mystere, 6.0, Nacra 6.0, Taipan 4.9, Taipan 5.7 and now a Wave (3 of them, actually)
I was constantly having to adjust padding, rollers or whatever.
Finally, it came to me. I stripped all that stuff off the trailer, bolted on two 3/4" Marine Plywood 4x8 pieces to make an 8x8 flat bed.
Went to the local carpet store trash container and pulled out some really cushy stuff and padded the trailer.
Voila! (a little french lingo there) a trailer that can handle any boat any time.
I can also load 4 Waves on my biggest Trailex which was designed to handle 2 20' cats with a total weight of close to 1000 lbs.
Another use of this idea.., just build some framing for siding and you can haul all kinds of stuff while you are not hauling a boat.
