AncientMariner: How big a hole? (I have drilled a hole through a ship's side before now.)
Presumably above the water-line. ??
It certainly was when I drilled it! Joking apart, it was about 4mm in diameter through the radio room bulkhead at bridge height. I tapped it for a 5mm brass screw. "Height of eye" was about 100 feet in that location. I was determined to achieve a low Z earth connection for the copper strip that I had run around the Radio-Telex MODEM.
Considering that I was using a hand-drill, the steel must have been a soft alloy or the drill bit rather sharper than expected.
