Steel boat owners of mature craft will be worried about where the pick lands.
Why??
That's close to a test not uncommon to check the hull is OK in the bilges, centre punch and a hefty blow with a big lump hammer. If it bounces off then all should be well, if not then you've done something wrong like letting water get inside the boat and need to get the grinder out and weld in a bit of plate. This I know.......
Best done out of the water...
