I have a 1972 Glastron 16' Bowrider and im wondering where to attach the tow rope for pulling a tube...i have 2 "u" shaped hooks that are mounted on the stern (the hoops you use to secure the boat to the trailer) and then there's 2 cleats, one on each side of the splashwell decks...where should i fasten a rope to pull tubes and the like...?
