I bought a Trailex aluminum trailer for my TheMightyHobie18 about 2 years ago. I love it. It is very light (less than 200lbs according to the shipping weight) and very easy to attach things to. I had the same problem everyone else does with the salt water. I was always worried about the corrosion. My past painted steel trailers were a nightmare in this respect.

I think you will be very happy with an aluminum trailer. Take a look at Trailex url=http://www.trailex.com]here[/url]

The best part about these is there are no welds. the whole thing is bolted togeather. To alay any concerns about that, I use a heavier grade version of the extruded aluminum to build machine tools and customized automation equipment frames. As long as the bolts are the torqued correctly they are not coming loose. This bolted extrusion is what lends itself so well to attaching extra stuff the the traielr frame without having to drill holes in it.
