Bertram-class air-sea rescue boat

The Bertram class was a two-ship class of air-sea rescue vessels of the Royal Australian Navy. Purchased to replace the old World War II class of 63-foot air-sea rescue vessel, they were found to be unsuitable for the proposed role.^[1] The vessels were subsequently employed as harbour personnel carriers and based at HMAS Waterhen. The vessels were disposed of in 1988.
