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?
There will be very little effect between the two ships as they pass.
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.

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.
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.
I should immediately alter course to starboard to avoid collision regardless of rules.
I should reduce speed and stop engines until the other vessel passes.

Via Inmarsat-C a message is sent to an Inmarsat-C mailbox with a positive delivery notification (PDN). The ground station will:
Send a PDN, as soon as the message is collected from the mailbox.
Send a PDN, if the message has arrived in the mailbox.
Send a PDN only after the recipient reads the message.
Send a PDN only if the message is deleted from the mailbox.
In the traffic list a coast-station indicates that there is a radio telex-message for a vessel. To call for the message one should put in:
After ga+ the telex number of the ship.
After ga+ the radio telex-command msg+.
After ga+ the MMSI number of the vessel.
After ga+ the call sign of the coast station.
In the Inmarsat Maritime Communications Handbook one can find information about:
Radio telex commands.

How is a Safety Management Certificate obtained?
Vessel is surveyed by MCA and certificate issued.
Ship owner has Document of Compliance issued, and vessel is assessed and holds all statutory certificates.
It is automatically issued when the ship is launched.
It is issued only after a successful dry-dock inspection.
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 collision regulations are based on ship courses through the water.
Because ARPA cannot calculate targets in true motion mode.
Because ground stabilisation automatically disables collision avoidance functions.
