I am looking at buying a 24' 1992 Monark Sun Caster 240 pontoon boat. It is in slips with no trailer. I see you can buy pontoon trailers but how to I make sure a trailer will fit the pontoon boat? Are all the pontoon boats the same measurements from pontoon to pontoon? I think I kinda know what the answer will be and that's going to have to measure the boat and measure trailers.
