From what I have heard and seen I have a few observations... They were early in the summer training cruise, but since they were maneuvering on the engine, and sails were furled and cadets were aloft manning the yards, an inexperienced cadet crew wouldn't have any impact - the Captain and bridge crew were experienced mariners. Pilot aboard. Tug alongside was probably tied aft initially backing out but had to move forward to assist the pivot to turn into the channel (tall ships have awful maneuverability near the dock). At that point I can't see how a single tug could have done much - with the wind and proximity to the bridge I think a second tug would have made a difference. Anchor detail was probably manned but by the time they realized they were out of control probably didn't have time to let go, and may have hesitated due to underwater infrastructure issues. The ship (from what I understand) has a single diesel-powered Controllable Pitch Prop - hydraulically controlled - typically very reliable. Winds were fairly strong at the time blowing directly upriver toward the bridge. Notice the huge Mexican flag on the mizzenmast out straight - I'd guess at least 15 kts gusts 20+. That's the main point - if the engine quit or CPP failed, the wind would have accelerated the ship toward the bridge very quickly - there's so much stuff aloft (masts, yards, rigging, furled sails) that I bet they'd easily go 3-5 kts downwind even without setting sail. Current was less than a knot, toward the bridge. Unfortunately, the masts and rigging are pretty fragile if you hit something, and half the cadets were aloft. That fragility at least meant no damage to the bridge, but lots of folks got hurt. We'll see what the NTSB says, but it looks like all the holes in the Swiss cheese aligned to make an otherwise challenging but manageable situation go totally wrong. I spent 4 months sailing Eagle as a cadet - including the Bermuda-Newport race for OPSAIL '76 with a bumper-car start - and can totally see this happening, mostly because these ships are a bitch to sail in close quarters. They look great and handle well under sail in open water, but are pigs otherwise.
