Thanks for the info. I imagine finding a suitable trailer will be like looking for hen’s teeth. I’m in rural Maine. Not many dual axels that aren’t in need of major rehab.
I've restored and flipped seven sailboats over the years and have bought and sold even more trailers than than that. The trailer market is odd. A decent used trailer often sells for $2,000 to $3,000, while a new one can run $3,500 to $5,000. Yet it's not uncommon to find a neglected boat sitting on a perfectly serviceable trailer for $400.
I've personally done this twice and have helped several friends find a "companion trailer" the same way.
For example, my Rhodes 22 currently sits on a dual-axle trailer that originally carried a 20-foot center-console fishing boat. I bought the boat and trailer package for $400 near Charlotte, brought it home, stripped the usable hardware from the boat, and then sold the bare hull for $100. If I account for the value of the hardware I kept, the trailer was essentially free.
Go onto Craigs List, or FB market place and set the max price at something like $800. You might find some widow who's husband's boat is now has a tree growing out of it and she just wants it gone. Sadley it is an all to common story.
One other factor to consider is brakes. I wouldn't want to be without them. Some states, including Virginia, do not require brakes on single-axle trailers, so brake requirements may influence your decision between a single- and dual-axle trailer.
