Bunk to Roller Trailer Question

[gman1001]

Hi there, my 1988 18' sits on the original Magic Loader aluminum bunk trailer which is in pretty good shape. All told, $200 invested in replacing old rusty bolts with stainless bolts etc... would make it a tip top trailer.

A friend wants to GIVE ME a 6yr old VENTURE galvanized roller trailer. It has white plastic fenders and pulse brakes.

The bunk trailer is great BUT two things stink about it.
1) taking it off the trailer even at high tide takes 3 men. The freagin thing sticks to the bunks!
2) Trailer floats, if your not smart about how which side of a dock you use, you'll find the trailer moving out at a right angle with the tide. major PITA.

SO, the question, what do I need to consider when changing trailers? Do I need to find tune the orientation of the rollers for my boat?

The previous owner used the trailer for his old Mako 20. I'm concerned my SC 18 with deeper V will hit the cross bars on the trailer.

Any thoughts on trailer setup appreciated.
