Every THS member learns that a Commutator (which is also the name of the THS quarterly journal) is a device that measures the list of a ship. How many of us have not dreamed of being on "Who Wants To Be a Millionaire" and have Regis say, "OK, Mike, you have no lifeline's left, but now, for a million dollars: "What is the name of the device that measures the list on a ship? a) gyroscope; b) leveler; c) commutator; d) listograph."
And now you come along, Dave, with one little paragraph that forced me to open my dictionary and may even force me to open my mind.
On page 115 you say that "a clinometer is a small instrument that measures the amount of list ("lean") on a ship." Then later on in the same paragraph you note that Quartermaster Hitchens testified that
Captain Smith "came back to the wheelhouse and looked at the commutator in front of the compass, which is a little instrument like a clock to tell you how the ship is listing."
So they must be synonyms, correct? Especially since you used them in the same context. When all else fails, check Webster's.
CLINOMETER -- any of various instruments for measuring angles of elevation or inclination.
COMMUTATOR -- an apparatus for reversing electrical currents.
Good God, Dave, what have you done? This is akin to telling Virginia there is no Santa Claus. Do I have to go back and change all my old Titanic magazines to CLINOMETER? Please explain. Maybe Michael Standart or Captain Eric can shed some light.
