The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.

How does a chemical detector tube work?

A sample of the atmosphere inside the compartment is drawn through a chemical reagent in a glass tube. The surface of the reagent becomes progressively discoloured as more contaminant vapour is detected in the sample. When this is read off the scale marked on the tube, the concentration of the vapour can be determined.

A sample of the gas from inside the compartment is sucked through a glass tube containing white cotton. As it does so, the gas becomes discoloured. The cotton will gradually dissolve and be replaced by the coloured gas, according to the concentration level. This may be read off a scale on the tube at the edge of the remaining cotton.

A sample of the air inside the compartment is pumped into a glass tube. As the pressure builds up inside the tube, a coloured stain can be observed, corresponding to the vapour pressure of the contaminant gas. The length of the stain corresponds to the percentage concentration of the gas.

The mositure in a sample of the atmosphere inside the compartment is allowed to soak into a strip of foam in a glass tube. This foam is impregnated with a reagent chemical. If it turns red, then the compartment is unsafe for entry; if it turns green, then entry is permitted.
