IMO it's a case of "the impervious horrors of a leeward shore" (or leeward bridge, in this case). (with apologies to Patrick O'Brian and William Falconer)
Looks to me like given the conditions that developed very rapidly there was little they could have done. They had minutes only and that channel is quite narrow. I mean with the luxury of hindsight and time, with disaster not imminent and no consequences for being wrong, it's easy enough to decide exactly what they should have done, but before the fact when you're in the situation as it evolves it's not so easy to hit on and execute the "correct" solution (if one even exists).
I disagree with the idea that it was poor seamanship to be at that spot at that time. Nowadays we have access to excellent weather forecasts, it's true, but nevertheless situations can develop which were not reasonably foreseeable. If every remote possibility that could conceivably happen were to keep us at the dock, why then we'd never go sailing. Clearly the forecast was not dire enough to keep that fleet in harbor for the day.
