While working on my boat today I ran into my mechanic. He had some photos of a salvage job he had just finished. A new 27' had sunk and rolled over on her side at the dock. I asked how such a nice new boat ended up in such a bad way. The owner pulled the plugs out of the blocks to drain her for winter, he never put the plugs back in. Once the pumps killed the batteries she sank. It's the second boat I've seen this month that sank due to the owner not having shore power on and batteries on charge. A Bayliner sank during Sandie and the pumps killed the batteries, rain water filled the boat and she went down.
