I've been to Simpson Bay and am familiar with the bridge and bridge schedule. 10 feet to spare is enough clearance to get through without incident. On a yacht that size, wind has very little to do with maneuvering compared to current. Wind usually has little effect, and current has a great amount of effect. It looks like he's going through at about 6 knots. Hitting the bridge on both sides of the yacht is a bit much. To me it seems like you could creep through at 2 knots and stand on the bow thruster and split the engines to move the boat sideways if needed to. Just like maneuvering in a tight marina. I have never run anything that big or nearly that big. But the yachts I've run over 100'-146' were very manueverable creeping at 2 knots, and adjusting postion with the bow thruster or engines, even with a lot of current provided it wasn't on the beam which it isn't at that bridge. just my 2 cents.
