Stonefish mines generally have two suspension lugs in order to facilitate handling operations e.g. winching. The winching was done on a ramp. It was meant to stabilize the vehicle while winching a heavy object on soft ground. In 1974 the station was fitted with new winching equipment. The location of the station and winching houses are marked by the Minories public house. For this reason, the "Polaris" has only a small winching area in the bow.
