I believe the keel rollers are just to prevent your boat from hitting
the trailer while loading and to assist with the loading. It is ok for
boats to be supported 100% by the bunks and bunks provide better
support than rollers. For best support make sure your boat is
positioned so that the edge of the transom is at the end of the bunks.
It is better not to have your transom hanging off the end of the bunks.


Except when it's a sailboat and the weight is more centered on the keel.
