I have a few questions. Can you fit three people on a 1300r if you are teens weighing about 100-150 pounds each. Not comfortably but fit. Another is could you bolt a tow hook on the back of a gp1300r and pull a two person tube, or could that crack the hull. Lastly, should I get the 1300 or 15f judging on fun? Please help!!! I'm not getting anything here.
