Due to my experience yesterday I would add one precaution, do not unhook the bow winch strap in the prep area. Take the extra few seconds after backing down the ramp, stop and unhook just short of the water
trust me it is a major pain to put a 17ft Javelin back on the trailer after it slides off 15ft short of the water! (A huge thanks to the 4 fisherman and 3 park rangers for lending a hand / anyone know of a simple gel coat repair kit?)
