Question 1

A vessel 'not under command' is defined as:

Accepted Answer

A vessel which through some exceptional circumstance is unable to manoeuvre as required by the Rules. Rule 3(f): a vessel not under command is one which through some EXCEPTIONAL CIRCUMSTANCE is unable to manoeuvre as required by the Rules and therefore unable to keep out of the way of another vessel. It covers any exceptional circumstance, engine failure, steering failure, casualty on board, not just specific mechanical failures.

Question 2

Which of the following is NOT listed as a vessel restricted in her ability to manoeuvre under Rule 3(g)?

Accepted Answer

A vessel constrained by her draught. Rule 3(g) lists RAM vessels including: laying/servicing/picking up a navigation mark, submarine cable or pipeline; dredging, surveying or underwater operations; replenishment or transfer of persons/provisions/cargo underway; aircraft operations; minesweeping; towing when unable to deviate. A vessel constrained by her draught (CBD) is a separate category under Rule 3(h).

Question 3

Under Rule 3, a vessel proceeding under sail when also being propelled by machinery is classified as:

Accepted Answer

A power-driven vessel. Rule 3(c): the term 'power-driven vessel' means any vessel propelled by machinery. Rule 3(b): 'sailing vessel' means any vessel under sail provided that propelling machinery, if fitted, is not being used. Therefore a yacht motoring with sails up is a POWER-DRIVEN VESSEL under the Rules and must display the black cone dayshape and power-driven vessel lights.
