The rudder is in the hard over position with the propeller stopped and the ship turning slowly. On a ship with a single fixed pitch right handed propeller and no thrusters, what can be done to make the ship increase the speed of turn without significantly increasing the forward speed of the ship?
Give the engines a short kick ahead
Give full astern on the engines until ship has stopped and then full ahead on the engines with rudder hard over
Give dead slow ahead on the engines and leave the rudder in the hard over position.
Give half astern on the engines as this will increase the rate of turn
The engines are going astern and the ship is making sternway of about 1.5 knots with the rudder hard to starboard. What effect will this have on the ship's progress?
This will give the stern a lift force to port
There will be no lift force and the ship will go straight astern
This will give the stern a lift force to starboard
The rudder will have no effect when the ship is making sternway, it should be in the amidships position when going astern
In the situation illustrated, what should be the distribution of the power requirements from the tugs, if the ship is to be moved sideways without changing the heading? Both tugs have similar bollard pull and are of conventional propulsion.
Much greater power on the forward tug than on the after tug while monitoring the gyro heading
Equal power required by both tugs, but monitor the gyro heading to ensure sideward movement only
It would be very difficult to predict the power requirements in this circumstance and it could only be found by observation.
Much greater power on the aft tug than on the forward tug while monitoring the gyro heading.
When handing over the con of a vessel to a pilot, should the Master insist in discussing the passage plan with the pilot while he is there to use his local knowledge and advice on the navigation of the ship?
The passage is well established and known by the pilot and a plan is therefore not necessary
The pilot would probably consider it unnecessary, be more interested in knowing the ship's characteristics and resist any passage planning discussions with the Master.
A pilot is responsible for the navigation whilst on board and will be very familiar with what is required, therefore discussing the passage plan is not necessary
A passage plan should be discussed between the Master and pilot, when under pilotage in the same way as discussed with the bridge team when deep sea

Modern slow speed, two stroke diesel engines often have locating pins or pegs to keep the piston rings in a fixed position. Why is this arrangement used?
It ensures the rings cannot be mixed up and that they are fitted in the correct order on the piston.
It avoids the risk of the ends of the piston rings being forced out by the gas pressure and catching on the scavenge ports.
The piston ring gaps can be kept in line to control the gas pressure on each of the rings.
The piston rings are more difficult to lubricate because of the slow operating speeds and will wear more quickly if they are allowed to rotate.
