Ship Manoeuvring, Handling. Test 8 – Online Maritime Tests

Experience has shown that the most successful method of double banking (when no tugs used) is:

With the larger vessel stopped and drifting in the water, fig. 4.
With both vessels underway, fig. 1.
With the smaller vessel at anchor, fig. 3.
With the larger vessel at anchor, fig. 2.

Consider the situation sketched below. How will you distribute the power of the tugs when you want to move the ship sideways without any yaw?

Full power on the aft tug, stop on the forward tug.
Full power on the aft tug, reduce on the forward tug.
Equal power on both tugs while checking the gyro.
Full power on the forward tug, the stern tug should hold back.

You are transiting a narrow channel. What can happen in this situation?

None of the mentioned will happen
The bow will be pushed away from the bank
The bow will be sucked towards the bank
The stern will be pushed away from the bank

When is a vessel deemed to be an overtaking vessel?

When coming up with another vessel from any direction abaft her beam
When coming up with another vessel from a direction more than 22.5 degrees abaft her beam
When coming up with another vessel from a direction more than 10 degrees abaft her beam
When coming up with another vessel from a direction more than 45 degrees abaft her beam

You are performing an overtaking manoeuvre in confined waters. What should you watch out for?

The bow may be sucked against, and the stern may be pushed away from the other ship as you pass.
There is nothing special to watch out for
That the other ship does not increase its speed
That you keep your ship on full ahead

How will you define squat?

Increase in draft to the point on your ship which is closest to the bottom
Squat is not relevant on your ship
The speed of your ship will increase
Decrease in draft of your ship

If a nylon mooring rope gets wet by immersion in water it undergoes:

No change in strength or length.
A decrease in strength of 20 %.
An increase in strength of 20 %.
No change in strength but some elongation.

You are duty officer and it is restricted visibility. On the radar you are observing a vessel foreward on your bow (7 n.m. off) and a vessel with approx the same speed and course on your starboard side, but with a CPA of 0,2 mm. You alter your course to starboard and cannot avoid the collision. What should you have done instead?

You should call the other vessel on the VHF and asked the Sen.Off.Deck to keep away.
You should altered your course to port and then avoided the collision.
You did not do anything wrong. The collision could not be avoided.
You should have reduced your speed to the minimum on which the vessel can be kept on course.
