bunk vs. roller trailers

[Briguy]

A few more observations. Even if you are not allowed to "power on" your trailer, what prevents you from driving the boat on the trailer and letting momentum carry you forward. Another thought, on my bunk trailer I added 2 rollers for keel support. It REALLY helps when winching. Finally, why winch the boat up the last foot on the ramp? Hook it, drive up the ramp to a level surface and then crank in the final 12 inches. Good luck!
