RYA Day Skipper Collision Regulations

Question 1

Under the International Regulations for Preventing Collisions at Sea (COLREGs), what lights must a power-driven vessel underway display at night?

Accepted Answer

A masthead light (white, forward), sidelights (green starboard, red port), and a stern light (white)

Answer

A power-driven vessel underway must show a white masthead light forward, green starboard and red port sidelights, and a white stern light. Vessels over 50m must show a second, higher masthead light.

Question 2

Under Rule 12 of the COLREGs, when two sailing vessels are on the same tack, which vessel must give way?

Accepted Answer

The vessel to windward

Answer

When two sailing vessels are on the same tack, the windward vessel must keep out of the way of the leeward vessel. The windward vessel has better manoeuvrability and visibility.

Question 3

What does Rule 5 of the COLREGs require every vessel to maintain at all times?

Accepted Answer

A proper look-out by sight and hearing, and by all available means

Answer

Rule 5 requires every vessel to maintain a proper look-out at all times, using sight, hearing, and all available means (including radar and AIS) appropriate to the prevailing circumstances.

Question 4

Under the COLREGs, what action should the 'give-way' vessel take?

Accepted Answer

Take early and substantial action to keep well clear

Answer

Rule 16 states that the give-way vessel must take early and substantial action to keep well clear. The action should be obvious to the other vessel and taken in good time.

Question 5

When approaching a narrow channel, which side should you keep to under Rule 9?

Accepted Answer

The starboard (right) side of the channel

Answer

Rule 9 requires vessels navigating in a narrow channel or fairway to keep as near to the outer limit of the channel on their starboard (right-hand) side as is safe and practicable.
