Along with the Fishermen's Museum (next door, basically), the Shipwreck Museum is the second small museum in Hastings that deals with the town's history as a port. As the name suggests, it is concerned with shipwrecks, excavations, and other artefacts rescued from the sea near Hastings. It's not quite as tiny as the Fishermen's Museum, but also free of charge.
Don't expect to spend more than half an hour (at most) in this place, but when you're in Hastings anyway you should drop by.
