The larger taffrail logs I've used also become worthless at less than about 2 knots -- the rotor just drags through the water instead of spinning -- so I've gotten in the habit of trying to ensure that it's hauled back when the speed drops, or the ship heaves to, or before we engage the main engine for any kind of tight maneuvering.

I used to have a spare rotator, until one sad day when I engaged reverse gear, having
forgotten that the log was still streamed.

That particular log had an inertia-wheel, a spoked wheel about the
sixe of a big dinner-plate, a few feet aft from the taffrail. Presumably
that was intended to keep it spinning smoothly, but I've never worked out
how, or if, that really worked, or if it mattered.
