The Admiralty needed to reach the planes quickly as they landed as any accident could lead to rapid sinking of the plane and loss of crew. Anecdotally, 2 such craft, 1 on either side of a (smaller) sinking flying boat, managed to ferry the stricken plane back to land.
After the flying boats left the Haven she was sold to a private buyer. Later, it was used for holidaymaker trips around Thorne Island in the Haven at 2 shillings per head.
