Not quite, gunzo. Left to themselves, sailors would guzzle the rum straight. Grog was ALWAYS mixed by an officer to make sure that didn't happen. It was mixed one part lime juice, two parts rum, and three parts water. The official British ration was one pint of rum per day to each sailor, and the grog was mixed in bulk to that amount. They got grog twice a day. They also could receive one gallon of "small beer" per day which was about what we'd call 3.2 beer.
They were a fairly sloshed lot most of the time.
