Regarding Propeller From The RMS Queen Mary. The other three propellers are in Long Beach. One is on display near the Queen Mary at the parking structure for the Carnival Cruise Terminal. One is still on the stern of the ship, with a viewing room accessible during tours. One is in storage near the ship, not open to the public.
This propeller weighs 32 tons, not 36 tons.
The Queen Mary had 4 massive propellers (or screws) to propel her through the waters at incredible speed. Each propeller was driven independently by its own turbine engine and was made of manganese bronze. The first set of propellers each measured 20 feet across and weighed 35 tons; however, these proved to produce too much vibration. The second set, and every set thereafter would consist of propellers that each measured 18.5 feet across,
