Deep ocean sailing yachts used to use these for electricity generation (for powering things like navigation equipment and radios) but now it's more common to use battery backed solar power.

I would say that boats have Wind Turbines rather than RATs.

The power comes much more from the wind than the vehicle moving through the air (though I am very aware that the speed of the boat affects the apparent wind the generator will experience)

Actually water turbines (aka hydrogenerators) are also an option, but it's less common.
