Do batteries fail?Do you understand the Rule of Twelfths? Do you know what a tidal diamond is? Do you know what an Admiralty chart is? On a current bearing ,is it the direction the current is going or coming from?Is the sea a living breathing entity? Is it bigger and harder than ALL the navies of the world put together?
