I recently loaded my 23 hunter onto it's trailer for the first time. Following someones advice I floated the boat up, not all the way, then winched it up the rest of the way, not an easy feat. With the the boat resting on the keel, the bow would not sit down into the rollers. In fact, I don't see how it could possibly do so. The front bow support made decent contact but I fell the package is not to stable without contact with the rollers. How do I fix this?Tommy B
