The full name is Pusser's British Navy Rum.  Excellent rum but it does burn a little (in a good way) on the way down.  Warning: Educational information is coming up.  So I did a little research re: Navy Rum.  Apparently the British Navy originally gave rations of French Brandy to their sailors in the early days.  But once Britain moved into the Caribbean and the Islands, they realized it was cheaper to give out locally-produced rum to their sailors.  Among the Brits, it was common practice to water it down a bit and add lime (to avoid scurvy) and this was called Grog.  This is partly where the term Limey probably came from, as well as the fact that they (Brits) basically ate limes while on long journeys to get enough vitamin C.
