Rating: ***

The Mary Alice B is a 65' steel tug boat that sank in 1975 whilst herself being towed. During the journey from Rockport to Detroit after completing a salvage operation, she began taking on water. Although efforts were made, they were to no avail and the crew eventually chopped her loose and watched her go down stern first. It wasn't until 1992 that her resting place was located.

The tug had numerous owners over the years and went by several names before coming to rest in an upright position, almost completely intact, in some 24m of water. She was built in 1931 for the US Army Engineers and began her career as Quintus but was subsequently renamed the Bonanka and the Lomax before being moved from Cleveland, Ohio back to Detroit in 1975 and finally renamed the Mary Alice B.

Divers can see the machinery on the aft deck, the pilot house and wheel in pristine condition. One diver could get a photo behind the wheel but the sediment would be kicked up too much for anyone following. This is a nice dive and being reasonably small is often done as the first of the day, to precede a longer dive on larger, shallower wrecks close by.
