The trouble comes when you lose power. I wrote an article for
"Soundings" two years ago about a guy on Lake Superior who lost one
engine on a Bayliner 39' due to an injector problem and his shaft broke
and dropped out of the other, causing a bit of water to come into the
boat. He had no plugs and was in the bilge trying to pound gardener's
knee pads into the hole to keep from sinking when he broached in 8'
waves. His antenna mounts broke, his wife (on shore) had the handheld
VHF and water was coming over the gunwales as it flopped form side to side.

The wife called the USCG, who came out and rescued him. They confirmed
the sea conditions when I interviewed them.

This was a classic sea achor situation. He has one now.
