Bumpers are on a car, Fenders are on a Boat!! I think they are used to "Fend off the dock" not "Bump off the Dock"
What do you use to tie your boat to the dock ???? Ropes or Lines???? I would have to say " Lines"
I think I have way too much Idle time on my hands today,
BTW T2x has a very amusing little story about
"Hey Thro me the Rope"
Please AX him to Splaine
