(a) The masthead light of high-speed craft may be placed at a height related to the breadth of the craft lower than that prescribed in paragraph 2(a)(i) of this annex, provided that the base angle of the isosceles triangles formed by the sidelights and masthead light, when seen in end elevation, is not less than 27 degrees.
[The words "with a length to breadth ratio of less than 3.0" were removed].
(b) On high-speed craft of 50 meters or more in length, the vertical separation between foremast and mainmast light of 4.5 meters required by paragraph 29a)(ii) of this annex may be modified provided that such distance shall not be less than the value determined by the following formula:
where:
-
y is the height of the mainmast light above the foremast light in meters;
-
a is the height of the foremast light above the water surface in service condition in meters;
-
Y is the trim in service condition in degrees;
-
C is the horizontal separation of masthead lights in meters.
* Refer to the International Code of Safety for High-Speed Craft, 1994 and the International Code of Safety for High-Speed Craft, 2000.

On pages 152-155, INTERNATIONAL Annex III, Section 1, paragraphs (a) and (c) are amended to read as follows:1. Whistles
(a) Frequencies and range audibility
The fundamental frequency of the signal shall lie within the range 70-700Hz. The range of audibility of the signal from a whistle shall be determined by those frequencies, which may include the fundamental and/or one or more higher frequencies, which lie within the range 180-700Hz (+/-1%) for a vessel of 20 meters or more in length, or 180-2100Hz (+/-1%) for a vessel of less than 20 meters in length and which provide the sound pressure levels specified in paragraph 1(c) below.
(c) Sound signal intensity and range of audibility
A whistle fitted in a vessel shall provide, in the direction of maximum intensity of the whistle and at a distance of 1 meter from it, a sound pressure level in at least one 1/3rd-octave band within the range of frequencies 180-700Hz (+/-1%) for a vessel of 20 meters or more in length, or 180-2100Hz (+/-1%) for a vessel of less than 20 meters in length, of not less than the appropriate figure given in the table below.

The diameter of the mouth of the bell shall be not less than 300 mm for vessels of 20 meters or more in length. Where practicable, a power-driven bell striker is recommended to ensure constant force but manual operation shall be possible. The mass of the striker shall be not less than 3 per cent of the mass of the bell.
[The words "and shall be not less than 200 mm for vessels of 12 meters or more but of less than 20 meters in length" were removed].
