I have a 22 ft Cuddy Cabin Four Winns that I often have trouble getting to load properly on my trailer. The trailer is a dual axle seabird that is complete with a new set of rollers. I also have a lower keel support and a upper keel support with a keel roller. I was wondering what kind of advice could you give me to help get this boat loaded more evenly. How far should the rollers on the back of the trailer be from the back of the boat? Where should that upper Keel support be in reference to the winch hook on the boat? How far should I have this trailer in the water to load? Please help. Sometimes loading it is such a pain.
