4 September 2013 Snowbird (ex HLD 6807 ex D25) is a wooden hulled ex Royal Navy Harbour Launch once used to ferry officers and crew around the Navy dockyards. Originally this particular vessel was based in Portsmouth.
HLD denotes Harbour Launch Diesel and the numbering scheme 6807 indicates that she was the seventh launch ordered in 1968.
Quite a number of this type of vessel were built and constructed to a design originating in the 1890's, apart from small profile changes and the introduction of diesel engines instead of steam the design remained largey unchanged. Most were built close to their intended homeport as the Admiralty sent out the plans to the RN naval bases who had them built locally.
They were operated by the Port Auxiliary Service which in 1976 was merged with the RMAS.
Next in line is Rainbird (ex HLD 6507, ex D23) a Harbour Launch built in 1965 by Groves and Gutteridge at Cowes.
Furthest from the camera is Stormbird (ex H.L.D. 6512, ex D12) which was built in 1965 by the Dorset Yacht Co, Poole.
