Union fitted with an innovation named the Hunter Wheel.
The Hunter Wheel was named after LT. W. W. Hunter and consisted of a conventional paddle wheel drum placed horizontally within the vessel below the water-line.
The paddles were so arranged as to project from a suitable opening in the side of the ship when at right angles to the keel. Water was kept from entering by a cofferdam
placed around the paddle wheel drum and against the side of the ship.
