(a) A power-driven vessel underway shall exhibit;
- a masthead light forward;
- a second masthead light abaft and higher than the forward
one; except that a vessel of
less than 50m in length shall not be obliged to exhibit such light but may
do so;
- sidelights;
- a sternlight.
(b) An air-cushion vessel operating in the non-displacement mode shall, in addition to the
lights prescribed in paragraph (a) of this Rule, exhibit an all-round flashing yellow light.(c) A WIG craft only when taking off, landing and in flight near the surface shall, in addition to the
lights prescribed in paragraph (a) of this Rule, exhibit a high intensity all round flashing red light.
- A power-driven vessel of less that 12 metres in length may
in lieu of the lights
prescribed in paragraph (a) of this Rule exhibit an all-round white light and sidelights;
- a power-driven vessel of less than 7 metres in length whose maximum speed does not
exceed 7 knots may in lieu of the lights prescribed in paragraph (a) of this
Rule exhibit an all-round white light and shall, if practicable, also exhibit sidelights;
- The masthead light or all-round white light on a power-driven
vessel of less than 12
metres in length may be displaced from the fore and aft centreline of the
vessel if
centreline fitting is not practicable, provided that the sidelights are combined
in one
lantern which shall be carried on the fore and aft centreline of the vessel
or located as
nearly as practicable in the same fore and aft line as the masthead light
or the all-round
white light.
