IRPCS Part 2 - Steering & Sailing Rules Flashcards
What does Rule 4 state?
Rules in this section apply to all vessels upon the high seas and in all waters connected therewith navigable by seagoing vessels.
Rule 5: What is the lookout rule?
Every vessel must maintain a proper lookout using sight, hearing, and all available means.
Rule 6: What determines safe speed?
Visibility, traffic density, manoeuvrability, background light, sea state, wind, draught, radar use, etc.
Rule 7: What is the risk of collision?
Assume risk exists if there is any doubt. Constant bearing, decreasing range indicates risk.
Rule 8: What action should be taken to avoid collision?
Action should be positive, made in ample time and with due regard to good seamanship.
Rule 9: What are the rules for a narrow channel?
Keep to starboard side. Avoid anchoring. Don’t impede vessels that can only navigate within the channel.
Rule 10: What is a Traffic Separation Scheme (TSS)?
Vessels should proceed in the correct direction of the lane. Avoid crossing if possible; cross at right angles.
Rule 11: When do the rules for vessels in sight of one another apply?
Only when vessels are in sight of one another.
Rule 12: Who gives way when two sailing vessels approach?
The vessel with the wind on the port side gives way. If both have the wind on the same side, the windward vessel gives way.
Rule 13: Who gives way when overtaking?
The overtaking vessel must keep out of the way.
Rule 14: What happens in a head-on situation?
Both vessels alter course to starboard.
Rule 15: Who gives way in a crossing situation?
The vessel which has the other on her starboard side must keep out of the way.
Rule 16: What is the responsibility of the give-way vessel?
Take early and substantial action to keep well clear.
Rule 17: What is the stand-on vessel’s responsibility?
Maintain course and speed but take action if necessary to avoid collision.
Rule 18: Who gives way under hierarchy of vessels?
Power gives way to sail, sail gives way to vessels restricted in ability to manoeuvre, etc.
What is the order of responsibility between vessels?
Not under command > RAM > Constrained by draught > Fishing > Sailing > Power-driven > Seaplane.
What should a vessel do if it is doubtful about another vessel’s intentions?
Take early and substantial action to avoid collision.
What does ‘alteration of course’ mean in IRPCS context?
Change in heading to avoid risk of collision.
When must a power-driven vessel give way to a sailing vessel?
Always, unless the sailing vessel is overtaking.
What is the correct action in restricted visibility?
Proceed at safe speed, engines ready for immediate manoeuvre, avoid altering course to port for a vessel forward of the beam.
When must you sound a danger signal?
If you are in doubt as to the other vessel’s intentions or actions.
What is meant by a ‘crossing situation’?
Two power-driven vessels crossing where there is risk of collision.
Who has priority, a vessel constrained by her draught or a sailing vessel?
A vessel constrained by her draught.
What does a vessel underway mean?
Not at anchor, aground or made fast to shore.
