Unidentified Schooner (Civil War)

This small vessel appears to have foundered in the 1860s.  She presents a very low profile.  The stern is square.  What was a small cabin is now gone, as is most of her decking?  Tiller steered, there are no deadeyes but blocks were used on her masts.  She has a centerboard, which became common construction in the 1840s. The vessel has a slight list to port and one of her masts has fallen to her port side.
Divers should watch out for the gill nets snagged on this wreck.
