Most (all?) blends with Navy in the name have rum as flavoring. Rum was the default alcoholic beverage of choice for sailors of old, pirates and naval people and anyone else aboard. When you see an old square rigger plowing along through the seas, think rum. Bizarre as it may sound, aboard my U.S. Navy minesweeper, once after an underway replenishment with rows of guys (including me) lined up on the weather decks hauling in lines pulling goods across from a much larger supply ship, we all got soaked to the skin continually for about two hours in cold sea water. When we were working, this was okay -- young guys working hard. But afterwards, we were all pulling off our soaked dungarees and got pretty cold. Here comes the corpsman with a case of airline size bottles of rum! I don't think this was official, just a morale booster done sub rosa. I quietly approached several of my Mormon and other conservative religious shipmates and inquired about their rum, and soon had a handful of bottles, which I happily imbibed. Now I know that wasn't intended. But it warmed me right up, for sure. Yo-ho-ho and a bottle of rum.
