I help you poly! i know its late:

Rule 23 -power driven Vessels Under way
(a) A power driven vessel under way shall exhibit:
(i) a masthead light forward;
(ii) a second masthead light abaft of and higher than the forward one;
except that a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;
(iii) sidelights: and
(iv) a stern light.
(b) An air-cushion vessel when operating in non-displacement mode shall, in addition to the lights prescribed in paragraph (a) of this Rule, exhibit an all-round flashing yellow light.
(c)
(i) A power driven vessel of less than 12 meters in length may in lieu of the lights prescribed in paragraph (a) of this Rule exhibit an all-round white light and sidelights.

(ii) a power driven vessel of less than 7 meters 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.

(iii) the masthead light or all-round white light on a power driven vessel of less than 12 meters in length may be displaced from the fore and aft centreline of the vessel if centreline fitting is not practicable, provided 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 all-round white light.

Rnli Y class boats are not fitted with nav lights but if need arises the helmsmans lifejacket light can be stuck ontop of his helmet with the velcro strip giving an all around white .

hang on, im sure a 'y' boat can do more than 7kts and so needs red/green. the white must be at least 1m above the red/green. ive now got an image in my head of a crewman having to stand up in the boat with his lj light sat on his helmet and with a glow stick duct taped to each knee

; ) think the minimum 2 miles visibility distance of the white light would be pushing it a bit too lol
Suppose its better than nothing though.
