Power Under 50m

Please note that it would be perfectly legal for an under-50 metre power boat to display the same lights as an “over-50 metre”.  (These can be seen on the following pages).

However, the lights below are legal for an under-50 metre boat and are based on separate port and starboard sidelights, with a masthead and sternlight.
