When a powerboat is operating at night, the white masthead light must be visible from both the front (fore) and the sides of the vessel. It should be mounted at least 1 meter above the sidelights and visible from an angle of 225 degrees. This ensures that other vessels can see the powerboat's position and direction of travel, enhancing safety on the water.
