PORTLAND (AP) – The Coast Guard says the fishing boat Lady Luck, which sank last year off the Maine coast with the loss of two lives, suffered a rapid loss of stability that caused it to capsize.

Investigators said Wednesday that while they may never really know what happened, evidence suggests that the trawler went down because of water on the decks, flooding in a storage hatch, or a combination of both.

The vessel, out of Newburyport, Mass., was located about 30 miles southeast of Portland at a depth of 530 feet. The Coast Guard used a remote-control submersible to examine the wreckage.

Neither of the two crew members, Sean Cone of North Andover, Mass., and Dan Miller of North Hampton, N.H., was ever found.
