Seaplanes and WIG Craft.
Where it is impracticable for a seaplane or a WIG craft to exhibit lights or shapes of the characteristics or in the positions prescribed in the Rules of this Part she shall exhibit lights and shapes as closely similar in characteristics and position as is possible.
Seaplanes normally have a “masthead light” in the forepart and sidelights on the wingtips, when underway on the water. A large seaplane at anchor may have white lights on the wingtips, in addition to white lights fore and aft.
