COLREGS Rule 25

(a) A sailing vessel underway shall exhibit:
(i) sidelights;
(i) a sternlight.

(b) In a sailing vessel of less than 20 m in length the lights prescribed in paragraph (a) of this Rule may be combined in one lantern at or near the top of the mast where it can best be seen.

(c) A sailing vessel underway may, in addition to the lights prescribed in paragraph (a) of this Rule, exhibit at or near the top of the mast, where they can best be seen, two all-round lights in a vertical line, the upper being red and the lower green, but these lights shall not be exhibited in conjunction with the combined lantern permitted by paragraph (b) of this Rule.

(d)(i) A sailing vessel of less than 7 m in length shall, if practicable, exhibit the lights prescribed in paragraph (a) or (b) of this Rule, but if she does not, she shall have ready at hand an electric torch or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent collision.
(ii) A vessel under oars may exhibit the lights prescribed in this Rule for sailing vessels, but if she does not, she shall have ready at hand an electric torch or lighted lantern showing a white light which shall be exhibited in sufficient time to prevent a collision.

(e) A vessel proceeding under sail when also being propelled by machinery shall exhibit forward where it can best be seen a conical shape, apex downwards.

HG, you could be sailing a little close to forum posting rules. Supposed to be acceptable for year 8 eyes and ears. What you are proposing would see them scarred for life!!!

it would be a nasty sight

Just had a thought of about 50 years ago when I slipped on a Quick cat Hiking board and ripped my shorts and when I slipped I was hanging off the side of the hiking board going past the finishing line with my shorts down near my ankles

a roar of laughter could be heard from the shore

I did read an article awhile ago where a captain of a ship disapproves with the use of white LED nav lights as they can be hard to distinguish with back ground stars on a horizon. Incandescent white lights have a unique intensity that is more favorable.

Just because they swap to LEDs doesn't create this problem, its been a problem since COLREGS were implemented

Every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.

In determining a safe speed the following factors shall be among those taken into account:
(a) By all vessels:
(iv) at night the presence of background light such as from shore lights or from back scatter of her own lights;

I left sections i-iii out because they aren't related to lights
