An interesting topic, the term "Heads" is used to describe the boat's toilet and its surrounding area. So a "Master Heads" refers to the toilet and its surroundings designed to be part of the Master cabin onboard. If we were descirbing just the toilet we would use "Head", or more widely, "Marine toilet".
@@quadramarine Sorry mate, it a head from the time when the toilet was at the head, or bow, of a ship. Heads is a misused British term. Heads are multiple toilets or multiple rooms with a toilet.
@@quadramarine The first known use of the term was in 1708, when Woodes Rogers, Governor of the Bahamas, wrote ‘head’ to refer to a ship’s toilet in his book, A Cruising Voyage Around the World.
