Anyone who says they have never done that has not had a boat for very long! Or owns a boat without a plug! I did it twice in one day (that is a story best told with a cold beverage in one hand and several people on this forum have heard more than once)
Now I put my plug in the captain's seat so I have to sit on it if I try and pull a knucklehead move again!
I'm sure no one has ever forgot to unhook their boat from the trailer before too!!!! (Is it too soon to bring this up Jack????)
