78 Chapter Two
Powerboats
Any power-driven vessel underway (including
sailboats under power) shall exhibit:
• A masthead light forward
• Sidelights
• Stern light
If the vessel is under 12 meters (39.4
ft) the masthead light and stern light may
be combined in one all-around white light.
If the vessel is over 50 meters it must
exhibit a second masthead light abaft of
and higher than the forward one (Figure
6-4).
