Boats and water can be very dangerous. The scuba diving aunt of a friend was so offended by her ex-lover she swam beneath his boat in the marina and
drilled holes in it. I can't recommend such behaviour.
This behaviour I do recommend. A way of forcing heartless profiteers to examine their actions.
It’s not the first time I’ve heard about a cordless drill wrapped in a garbage bag being used underwater to add some unplanned through hull
fittings either
