Re: Steaming light
Of course if you choose to have your steaming light illuminated then you are , propeller engaged or not, a power boat. There can be no quibble about that, surely.
I guess the question would be answered by the racing fraternity. Pretty much every top flight racing boat these days has their engine running 24 hours a day in order to keep power going to the canting keel mechanism and their plethora of electronic equipment.
