Shooting screws through the hull is not really recommended by the manufacturer as a method of antifouling a boat, but it seems to have worked in this case as it scared the sh1te out of all the pesky marine growth.
"After yesterday's fishing trip a friend asked me to look at a boat on a work rack at the marina. He said the owner just had new upholstery made for the inside. I looked. I got sick. I laughed.
How do you describe this?
Seems the owner sent the panels, seats and bolisters out to be re-done. Then HE put them back into the boat. Used indoor dry wall screws. Long ones. Put the boat in and quickly took on water. The marina pulled the boat."
