The Irma C, an old coal barge, rests a few miles east of the G&D wreck.  Her remains have been reduced to a small low-lying patch of wreckage, so that fishing or dive boats may find it a little tricky to anchor on her.

 Once in the water, divers will usually find good visibility and an abundance of marine life on this wreck which rests in 105 feet of water. The way her ribs have spread out over time makes perfect homes for lobsters, which are abundant on this as well as other wrecks in the vicinity. According to diver Jim Fazzolare the wreck has a rudder covered in nets in her stern and a winch in the bow.
