“It is both the duty and the tradition of the Royal Navy to engage the enemy wherever there is water to float a ship” A “fast play” game covering primarily the naval engagements on Lake Tanganyika during the First World War, and also any number of real and hypothetical small craft actions during the period 1910-1920. Written with 1/600 scale models in mind, their inspiration being the models designed by North Head Miniatures of New Zealand. As well as the tactical rules, a set of mini campaign rules is included. Actions fought using the tactical rules tend to be short and sharp, and so the campaign is easily playable in a few evenings, or as a club project for a day.
