I watched a husband and wife launch a boat one day it was funny so I will tell ya'll here. The husband went down bought a new boat they got to boat ramp he turned it around backed it up and had it lined up so she could back it up the rest of the way she did that just fine she put the truck in park got out he set the motor in water and started it she was unhooking the trailer from the truck just as tongue got high enough there went the boat right to the bottom of the ramp in the water he was swimming to shore and she was crying what did I do wrong you to me to unhook the boat he yelled back ya the boat not darn trailer. Moral is to teach all new comers on the proper way to unhook from the trailer, I was rollin in laughter
