You are on a sailing vessel, underway in open water. This vessel is sighted on the starboard bow, on a steady bearing and the distance is closing. By the International Regulations for the Preventing Collisions at Sea, what action will you follow?
This vessel is clearly a power-driven vessel and I anticipate that the bearing will therefore close and she will pass ahead at a safe distance.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I am required to keep out of the way. I will make a broad alteration of course to starboard.
By Rule 18, a power-driven vessel underway shall keep out of the way of a sailing vessel. I will maintain my course and speed, but will continue to monitor situation to ensure the other vessel takes avoiding action.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I will maintain my course and speed.

Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?
True motion does not provide the collision risk of targets as only true vectors are available.
The true vector can never give an indication of collision risk with another ship.
The “aspect” of the target is confused, so the Regulations for Preventing Collisions cannot be accurately applied.
Because this display is only ever used for navigation.
What corrections must be applied to the echo sounder reading to compare the depth of water with the depth printed on the chart?

You are on a power-driven vessel underway in open water. This vessel is sighted directly ahead. The distance is closing slowly. What action will you take under the International Collision Regulations and why?
The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.
I will maintain my course and speed. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.
I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.
What would be the effects of a ship passing into shallow water?

There is no noticeable difference in performance of the ship.
The speed is not affected, but more rudder is required to steer the ship.
Why should Ground Stabilised True Motion display mode be avoided when using the ARPA for anti-collision purposes?
The Relative Motion display and relative vectors is the only display to use for anti-collision purposes.
The true vector can never give an indication of collision risk with another ship.
The collision regulations are based on ship courses through the water.
True motion does not provide the collision risk of other ships.

Relative vectors, sea stabilised.
Relative vectors, ground stabilised.
When a ship is lying at anchor in a tidal area using both forward anchors, to what particular aspect should the officer of the watch be paying special attention?
The two anchors will restrict the ships swing with the tide and the ship may not lie to the prevailing current and wind.
The tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.
When the ship swings to the tide the direction of swing should be controlled to avoid the anchor cables becoming wrapped round each other.
The ship will become controlled by the tide and the wind will not be allowed to have any effect on the direction the ship lies at anchor.
What corrections must be applied to the echo sounder reading to compare the depth of water with the depth printed on the chart?
Allowance for the ships speed.
The distance between the pulse Transmitter and Receiver.

Acquire the buoy at the entrance to the channel and on relative vector display alter course to make the vector of the buoy pass directly through the centre of the screen.
Select ground stabilised true motion display and alter course so that own ships true vector passes through the middle of the entrance to the channel.
If your vessel is fitted with wires on self-stowing “split drum” winches, the advantage of having these split drum winches is:
Increased brake holding capacity due to the ability to keep the paid out wire in a single layer on the drum.
Less chance of the wire being jammed in the reel.
All the listed alternatives.

Where can a ship expect an act of piracy to take place?
At the south end of the Red Sea.
Two ships travelling in opposite directions are to pass each other in a narrow river, as illustrated. Explain what is likely to happen as they pass each other?
Due to interaction, the bows will repel each other, and then when alongside each other the two ships will be sucked together and finally the sterns will be repelled as they start to pass clear.
There will be very little effect between the two ships as they pass.
Due to interaction, the bows will attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.
As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.
