It came with the boat. So for these year i hope it will do. The boat is a 16ft Larson tri hull. I try to pull the boat forward but I dont know if I am going to far. Can the trailer crank go behind the bow support if so I might get it all the way on then. My goal is to try and use a transom saver. but I dont want to but to much weight on the tongue. also is this the best kind of trail for a tri hull? Here are some pics I think the trailer is a load rite 1200-L (?) What advice do you have. Thanks
