An abandoned ship with a vampire gives us the Blood Vessel trailer

I do like that film title.

Somewhere in the North Atlantic, late 1945, a life raft adrift at sea, and in it, the survivors of a torpedoed hospital ship. With no food, water, or shelter, all seems lost until a seemingly abandoned German minesweeper drifts ominously towards them, giving them one last chance at survival — if they can survive the bloodthirsty monsters on board.

Directed by Justin Dix, the film stars Nathan Phillips, Alyssa Sutherland, Robert Taylor, Christopher Kirby, John Lloyd Fillingham, Alex Cooke, and Ruby Isobel Hall.

Blood Vessel is currently available on Shudder.
