RE: Wont go on straight
Here's another view. My first bunk trailer was a Karavan and had centerline rollers... loaded right every time. The keel line's up on the rollers and boat comes on straight. My next two trailers, an EZ Loader roller and then bunk trailer, did not have centerline rollers. If the boat is leaning off center in the water(even just a few degrees), it will load tilted to the right or left (if the boat is not making contact with centerline rollers). Guide-ons would not help, I tried em. Now, I simply make sure the boat is sitting balanced (port to stbd) in the water before I winch it on the trailer. I will stand in the center of the boat at the dock, and slide the cooler left to right until the boat is level. Without a cooler, try turning the wheel left or right to level the boat. It loads perfectly like this. Give it a try. Adjusting the bunks into some wierd a$$ed unsymmetrical configuration is not usually the answer. I would make sure the bunks are symmetrical. By the way, my boat is a 20 degree deadrise. Balance should have lesser effect with lower deadrises.
