Lamp positioning
General recommendations
When the lamp is operating, the light should not
be obstructed or concealed by superstructures
or other objects.
Position in relation to vessels centre line
The masthead lamp must be positioned in a
vertical position and at a right angle to the
vessel's centre line with the signal direction
arrow pointing straight ahead (see Fig. 1).
Horizontal positioning
The light shall be displayed forward of
amidships, except on a boat less than 20 metres
in length, where the masthead lamp need not
be placed forward of amidships (see Fig. 2), but
must be placed as far forward as practicable
taking into account the vertical positioning
requirements above the gunwale or sidelights –
as described below.
Vertical positioning
On a powerboat
- over 20 metres in length: the masthead lamp
must be placed at a height above the hull of
not less than 6 metres. The height must be
more than the breadth of the hull, but no more
than 12 metres above the hull.
- between 12 and 20 metres in length: the
masthead lamp must be placed at a height
above the gunwale of not less than 2.5 metres.
- less than 12 metres in length: the masthead
lamp must be placed at least 1 metre higher
than the sidelights.
Note: Consideration for country specific rules
may be required.
