You are approaching shallow water with Under Keel Clearance of 15%. What speed should you have when entering and when should you slow down?

About 6 - 7 knots, slow down 30 minutes before entering.
Maintain normal sea-speed, no need to slow down.
Reduce to slow or less in due time before entering.
About 10 knots, slow down 15 minutes before entering.

You want to stop your ship as quickly as possible without too much change in the heading. What can you do to achieve this?

Do a zig zag manoeuvre
Make a complete turning circle
Put the engine full astern
Use the rudder hard over both sides while reducing engine power, so-called 'high frequency rudder cycling'.

Your ship is equipped with a single, right-handed fixed screw. Steaming full ahead you reverse the engine to stop the ship. How will the ship react? No wind or current.

She will most likely sheer to starboard and gradually loose headway
She will stop on 1,5 times the ship's length
She will most likely continue on a straight course
She will most likely sheer to port and stop rather quickly

What is most pronounced about a ship with good course stability?

It will maintain course no matter how much rudder you apply.
When you apply the rudder, she will continue to turn when rudder is put amidships.
When you put rudder amidships, she will continue a straight course.
When you apply the rudder it will take time before she answers to it.

A tug is connected in a line at your bow. Will the bollard pull be the same at any speed?

No, when the speed exceeds 5 knots we have not much help in a tug.
No, when the speed is increasing, the bollard is also increasing.
Yes, the bollard is the same at any speed.
We will have the best use of the tug when the ship makes sternway.

Which of the alternative methods of using a tug when escorting your ship through narrow waters do you think is the most effective in case you loose steering power?

Made fast forward on either shoulder, ready to push (figure 3)
Running free alongside, ready to be made fast (figure 2)
Made fast in a line at the bow (figure 1)
The tug's bow against my stern, made fast with lines. By moving the tug to either side of my stern, this will help to steer the ship (figure 4).

You are going to leave a crowded anchorage by making a 180 degrees turn. You ship has a right handed propeller and you can turn either way. How can you make the turn using as little space as possible?

Rudder hard to port, full astern. After you gain some sternway, rudder hard to starboard and full ahead.
Full ahead, rudder hard to starboard.
Full ahead, rudder hard to port.
Rudder hard to starboard, full ahead. Rudder hard to port, full astern. Repeating this maneuver until you have made the turn.

Which sailing vessel (A or B) keeps out of the way of the other?

A keeps clear of B
B keeps clear of A
