Question 1

A vessel not under command shows which lights at night?

Accepted Answer

Two all-round red lights in a vertical line, with sidelights and a sternlight when making way through the water.. Rule 27(a): a vessel not under command shall exhibit two all-round red lights in a vertical line where they can best be seen; when making way through the water, she shall also exhibit sidelights and a sternlight. By day, she shall exhibit two balls or similar shapes in a vertical line. Under Rule 27(b), a vessel restricted in her ability to manoeuvre, except a vessel engaged in mineclearance operations, exhibits three all-round lights in a vertical line, red-white-red, whether making way or not. When making way through the water, she also exhibits masthead light(s), sidelights and a sternlight.

Question 2

Under Rule 27(b), a vessel restricted in her ability to manoeuvre, except a vessel engaged in mineclearance operations, making way through the water shows:

Accepted Answer

Three vertical lights showing through 360°, red, white, red, together with masthead lights, sidelights and a sternlight.. Rule 27(b) requires a vessel restricted in her ability to manoeuvre, except a vessel engaged in mineclearance operations, to exhibit three all-round lights in a vertical line: red, white, red. When making way through the water, she must also exhibit masthead lights, sidelights and a sternlight. Her day shapes are ball, diamond, ball in a vertical line. When at anchor, she generally exhibits the lights or shape prescribed by Rule 30 in addition to her restricted ability to manoeuvre signals, subject to the exception for dredging or underwater operations in Rule 27(d).

Question 3

A vessel engaged in mineclearance operations shows:

Accepted Answer

Three all-round green lights, or three balls by day, indicating that vessels should not approach within 1000 m.. Rule 27(f): a vessel engaged in mineclearance operations shall exhibit three all-round GREEN lights or three balls in addition to the lights prescribed for a power-driven vessel underway. The shape/lights indicate that it is dangerous to approach within 1000m of the mineclearance vessel. This is unique, three green lights are used only for mineclearance and indicate an extreme danger zone.
