With the dual rudders there won't be a direct prop-wash on the rudders, and with the bow thruster so far aft (almost directly under the mast which is presumably the CE for crosswinds) there won't be optimal pivot assistance, especially if the centerboard is raised.

IMHO they should have put the thruster closer to the bow. I find it's helpful to use the bow thruster in slow reverse to help pivot-steer the boat when backing into a tight spot. I depend on prop-wash and quick momentary throttle bursts to pivot the bow in slow forward. In slow forward it's tough to coordinate use of prop-wash and thruster at the same time, so I tend to use one or the other alternately but not both together.

Pretty boat above the waterline. I hope that guy has an easy approach to/from his dock.
