A masthead Tri Color and a steaming light are all that is required on a
sailboat that is under power only. There is nothing I know about that states
I need my Nav lights at any particular height. Many sailboats have their
running lights mounted on the hull, some on the Cabin others on rails.....
but most utilize masthead only.

Not that it makes a difference to a container ship or tanker since nobody
would be on the bridge any way but maybe someone would see it while fetching
more ice to the lounge. ;-P
