Maiden voyage for the new Sabre FTD this Saturday,want to make sure things go smoothly. Reading posts on trailer depth for loading and unloading, most say leave about 6 to 8 inches of outside (short) bunks out of the water for loading. Will the same depth work for unloading? I know Cats are designed to be power loaded and unloaded, just want to avoid hitting anything as I launch for the first time. Thanks!!Don
