The HMT Rinovia was a steam fishing vessel, requisitioned as a mine sweeper in 1939. In 1940, it hit a mine and sank. It now lies in around 55m and is a really nice shallow trimix dive. It is small enough to be covered in a single dive, even at this depth. Lying fairly intact and upright, it can have a covering of fishing nets, which are themselves, normally covered in Plumose anemones.
