Ruby E

An upright 1934 Prohibition cutter with a wheelhouse to look into

The Ruby E is the former Coast Guard cutter Cyane, a 50-metre ship (165 feet) built in Seattle in 1934 to enforce Prohibition and sunk as an artificial reef in Wreck Alley in 1989. She sits upright and intact, dived between 20 m and 26 m, with strawberry anemones on her structure and several easy entry points.

Also known as USCGC Cyane.

The dive

The Ruby E was the second ship sunk in Wreck Alley, and she settled well: upright and intact on the bottom, with only the slightest list to the port side and her bow pointing north. The dive runs between 20 m and 26 m (65–85 ft), and every area of the wreck except the bilge is easily accessible.

The wheelhouse, with its round portholes, is the easiest place to enter, and the ship has a number of other easy penetration points. They should be used only with experience and caution. The engine room holds two large diesel engines with their heads off. Strawberry anemones grow over the structure, and rock scallops live on the wreck.
