Haymans Royal Dock Navy Strength Gin is their high proof offering, bottled at the legendary proof point where supposedly soaked gunpowder will still ignite. The gin is named for the Royal Dock in Deptford, just outside London along the Thames river where it was once one of the most important shipbuilding yards in England.

By the 1860s, the time at which the Hayman family was supplying gin to officers in the Royal Navy, the dock at Deptford was a shadow of its former glory. Shipbuilding was entirely shut down at Deptford by 1869. No longer the center of shipbuilding, it did have an important function as a victualling yard, which it continued to do so until a century later. So naturally, if your gin was to make it on to the ship, it needed to go through Deptford.
