the propeller shaft in the after peak tank is provided with inboard and outboard seals.these seals contain nitrile rubber or viton lip seal which seals against the bronze liner shrunk fit around the cast iron propeller shaft.after a few years it creates grooves on them and naturally looses sealing and sea water can easily find its way inside.this reduces the lubrication effect and creates wear if the bronze liner.now as there is enough clearance the shaft will come down by certain amount because of the propeller weight.this drop in propeller shaft is termed as propeller drop and is measured by POKERS gauge.

To deploy it using an aircraft.

Before taking the measurement, we have to remove the rope guard first.Also to make sure weather the vessel have the poker gauge or not.This poker gauge is use to measure the propeller shaft drop (known as propeller wear down). After dismantling the rope guard, make sure to turn the blade to one position refer to the marking.Normally, we take top measurement and bottom measurement.
The crew dropped ropes from the aircraft when it was landing because they were doing a routine landing.

They follow a curve due to speed of the aircraft and gravity.
