Rule 40 - Application Contracting Parties shall use the provisions of the Code for Implementation in the execution of their obligations and responsibilities contained in the present Convention.

Rule 41 - Verification of Compliance a Every Contracting Party shall be subject to periodic audits by the Organization in accordance with the audit standard to verify compliance with and implementation of the present Convention. This height shall be measured from the positionvertically beneath the location of the light. Vertical positioning and spacing of lights a On a power-driven vessel of 20 metres or more in length the masthead lights shall be placed as follows: i the forward masthead light, or if only one masthead light is carried, then that light, at a height above the hull of not less than 6 metres, and, if the breadth of the vessel exceeds 6 metres, then at a height above the hull not less than such breadth, so however that the light need not be placed at a greater height above the hull than 12 metres; ii when two masthead lights are carried the after one shall be at least 4.

When however a masthead light is carried in addition to sidelights and a sternlight or the all-round light prescribed in Rule 23 c i is carried in addition to sidelights, then such masthead light or all-round light shall be carried at least 1 metre higher than the sidelights. They shall not be so low as to be interfered with by deck lights. On a vessel of 50 metres or more in length this forward anchor light shall be placed at a height of not less than 6 metres above the hull.

Horizontal positioning and spacing of lights a When two masthead lights are prescribed for a power-driven vessel, the horizontal distance between them shall not be less than one-half of the length of the vessel but need not be more than metres.

The forward light shall be placed not more than one-quarter of the length of the vessel from the stem. They shall be placed at or near the side of the vessel. Details of location of direction-indicating lights for fishing vessels, dredgers and vessels engaged in underwater operations a The light indicating the direction of the outlying gear from a vessel engaged in fishing as prescribed in Rule 26 c ii.

This light shall be placed not higher than the all-round white light prescribed in Rule 26 c i and not lower than the sidelights. In no case shall the upper of these lights or shapes be at a greater height than the lower of the three lights or shapes prescribed in Rule 27 b i and ii. Screens for sidelights The sidelights of vessels of 20 metres or more in length shall be fitted with inboard screens painted matt black, and meeting the requirements of Section 9 of this Annex.

On vessels of less than 20 metres in length the sidelights, if necessary to meet the requirements of Section 9 of this Annex, shall be fitted with inboard matt black screens. With a combined lantern, using a single vertical filament and a very narrow division between the green and red sections, external screens need not be fitted.

Shapes a Shapes shall be black and of the following sizes: i a ball shall have a diameter of not less than 0. Colour specification of lights The chromaticity of all navigation lights shall conform to the following standards, which lie within the boundaries of the area of the diagram specified for each colour by the International Commission on Illumination CIE.

The boundaries of the area for each colour are given by indicating the corner co-ordinates, which are as follows: i White x 0. For prescribed lights the value of K shall be 0.

Horizontal sectors a i In the forward direction, sidelights as fitted on the vessel shall show the minimum required intensities. The intensities shall decrease to reach practical cut-off between 1 degree and 3 degrees outside the prescribed sectors. From 5 degrees within the sectors the intensity may decrease by 50 per cent up to the prescribed limits: it shall decrease steadily to reach practical cut-off at not more than 5 degrees outside the prescribed sectors.

Vertical sectors a The vertical sectors of electric lights as fitted, with the exception of lights on sailing vessels underway shall ensure that: i at least the required minimum intensity is maintained at all angles from 5 degrees above to 5 degrees below the horizontal; ii at least 60 per cent of the required minimum intensity is maintained from 7. Intensity of non-electric lights Non-electric lights shall so far as practicable comply with the minimum intensities, as specified in the table given in Section 8 of this Annex.

Manoeuvring light Notwithstanding the provisions of paragraph 2 f of this Annex the manoeuvring light described in Rule 34 b shall be placed in the same fore and aft vertical plane as the masthead light or lights and, where practicable, at a minimum height of 2 metres vertically above the forward masthead light, provided that it shall be carried not less than 2 metres vertically above or below the after masthead light.

On a vessel where only one masthead light is carried the manoeuvring light, if fitted, shall be carried where it can best be seen, not less than 2 metres vertically apart from the masthead light. General The lights mentioned herein shall, if exhibited in pursuance of Rule 26 d , be placed where they can best be seen. Signals for trawlers a Vessels of 20 metres or more in length when engaged in trawling, whether using demersal or pelagic gear, shall exhibit: i when shooting their nets, two white lights in a vertical line; ii when hauling their nets, one white light over one red light in a vertical line; iii when the net has come fast upon an obstruction, two red lights in a vertical line.

Signals for Purse Seiners Vessels engaged in fishing with purse seine gear may exhibit two yellow lights in a vertical line. Vessels indicate their intention to maneuver by using sound signals. If you do not agree with or understand clearly what the other vessel's intentions are, you should sound the danger or doubt signal 5 short, rapid blasts. Each vessel should then slow or stop until signals for safe passing are sounded, understood and agreed to.

The danger or doubt signal can also be used to tell another vessel that its action is dangerous.
