I may get flamed here... but I think that anyone that trailers these boats any distance with anything under a 1 ton truck and no trailer brakes is suicidal.
Things may not go wrong, but things sometimes do... You have to prepare for the worst to happen when your on the road with other (insane) drivers. The original trailers came with only brakes on the front axle. I decided to put brakes on both. I tell you it's a pain, cause every fall I need to overhaul the brakes cause salt water gets into the slave cylinders even with the fresh water flush system I installed. But I feel it's necessary. Mostly for safety, but also cause I love my boat! (there I admitted it!
