Ship Manoeuvring, Handling. Test 11 – Online Maritime Tests

If your vessel is fitted with wires on self-stowing 'split drum' winches, the advantage of having these split drum winches is:

No crushing of the wire.
Increased brake holding capacity due to the ability to keep the paid out wire in a single layer on the drum.
All the listed alternatives.
Less chances of the wire being jammed in the reel.

You are underway on a power driven vessel in open water when you observe a crossing power driven vessel approximately 8 miles away at 22 degrees on your port bow. Bearing steady, what action do you take?

Maintain course and speed with caution as he is the give way vessel
Alter course to port and pass around his stern
Call him on VHF before deciding on what action to take
Reduce speed to let him pass ahead

If you are ordering chain for use as 'Chain Stoppers' on mooring wires, the length of chain usually recommended for use in each stopper is:

3.5 to 4.5 mtrs.
1.5 to 2.5 mtrs.
4.5 to 5.5 mtrs.
2.5 to 3.5 mtrs.

You are sailing in shallow water, with 15% Under Keel Clearance. How will the stopping distance be, compared to deep water?

Longer
About 1 ship-length longer
The same as in all depths
Shorter

Your ship is operating with a right handed propeller and no thrusters. What can you do to control your ship in the situation shown?

Let go starboard anchor 1 - 1,5 shackles
Give hard starboard rudder
Let go port anchor 1 - 1,5 shackles
Increase the speed

Scharnow Turn
Evinrude Turn
Direct Turn
Williamson Turn

You are duty officer on the bridge. An eye-witness is reporting man-overboard. Which of the following actions are to be considered as the correct manoeuvre in this situation?

Evinrude Turn
Williamson Turn
Direct Turn
Scharnow Turn

It is important that the brake holding capacity of a self stowing winch drum should not exceed the breaking strength of the wire or rope wound onto it. A certain percentage of extra strength is therefore recommended for the wire or rope over the brake holding capacity of the winch. So, for a winch of brake holding capacity of 60 Tons you would order a wire of breaking strength:

80 Tons.
100 Tons.
75 Tons.
61 Tons.

If you are required to splice an eye on a mooring wire (using the recommended 5 full tucks and 2 half tucks) the effective breaking strength of the wire will now be affected by the splice, and you would expect:

A reduction in strength of 1% to 5%.
No reduction in strength.
A reduction in strength of 30 % to 40 %.
A reduction in strength of 10 % to 15 %.

In ship handling terms, what is meant by 'sinkage'?

Sinkage is the extra draft a vessel experiences when comparatively heavily loaded amidships.
Sinkage is the change of draft experienced when moving through water.
Sinkage is the deepest draft a vessel obtains aft when moving through the water.
Sinkage is the extra draft a vessel experiences when comparatively heavily loaded both ends.
