As Sherman said,you want to buy trolling bags and not drift bags.Trolling bags are heavier and won't break apart as fast as drift bags.Most guys in the smaller boats use a plate behind prop,an electric trolling motor or a kicker.Difficult to tie bag to the front of a shorter boat and get enough length of rope and angle before bag gets into prop.You also want to tie rope to back of bag and tie to stern.This prevents bag from moving under boat or off to side of boat.Good luck.
