Sitting here reading about sail boats being easier to maneuver in harbors cause of bow thrusters, after having dealt with major prop walk just the other day in high winds while docking.

Such high winds impacts motor yachts as well, especially high sided ones. Most of the boats I've sailed are without bow thrusters require lines to manveur in even moderate winds in tight marinas. Bow thrusters makes it push button in moderate wind.
