My first thought regarding the dismasting, however, was to wonder whether they might have been sailing under a headsail alone, without the main to act as a reinforcing/stabilizing influence in the event of such a 'sudden stop', and the massive inertia that could put on the rig.. A second glance at the photos, however, quickly confirmed they did have the main unfurled...

Nevertheless, one thing I never like to see, are boats beating to weather in a good blow, under headsail alone... I'm afraid many people don't appreciate the importance the mainsail in such a scenario, and how helpful the stabilizing effect even a deeply reefed main can have, in helping to reduce mast pumping, and keeping the mast in column...
WHen beating to weather the main is by and far the best sail. Excluding for a moment where the center of effort is placed (and the tendency for a weather helm which is important), the main allows you to tack with little energy and effort from the crew. Especially if the crew is tired, you can come about to the same angle (more or less) and it is easy-cheesy.

Going to weather with just a jib is a typical novice mistake (IMHO).

Now when I run, especially if I am close to a dead run (which I hate to do), I will often go with just the jib. If I run the main, depending on the wind, I typically set a preventer. I assume you do too?
