The Colleen was a canal tugboat which towed barges on the Erie Canal between New York City and the Great Lakes. She also helped dock ships in port.
the Colleen is a near twin to the Spartan. At about 60 ft depth, large holes in the roof make it easy to drop down several decks inside the wreck, and still have daylight in sight above. Look for lobsters dug in under the edges of the hull, along with a great many Sea Bass. The rudder is cranked 90 degrees to one side, leaving plenty of room to swim through the gap where the propeller should be. At least one APC lies close-by off her stern, upside-down, and a reef ball lies on the aft deck.
