I''ve only been dismasted (luckly, I guess) on smaller one designs, my Lightning, for one.
I am not a N.A. but with the reduced weight aloft that the Carbon rig
represents, in general you would have less mass acting on the "Lever" and therfore have a boat whose pitching might be faster (read more violent), yet less severe (read shorter arc). I would find that a less "unsettling" motion than the longer, slower roll that results in more mass at the ends, or extremes of the "Lever". This would actually be more of a noticable effect on the "pitching" motion as the "roll" is generally dampened by the sails you have up. That is assuming your sails are up!
I think the reference to a boat being more suseptable to rolling over after a dismasting would be more related to your rig
in the water, still attached by the remains of your standing and running rigging
. That is why it is essential to cut away the rig
as soon as possible after the catastophe. Assuming you are in a storm at the time.
Remember the scene in "Master and Commander" when they lost part of the rig
in a storm and it threatened to sink the ship? It was because with the rig
in the water, still attached to the ship, the ship was not able to handle the waves in anything resembling a normal seakeeping motion, turning her beam-to and preventing her from riding with the waves. Once the rig
was cut lose, the boat was able to return to her "feet" as it were.
During my "Boat Familiarization" walk through before a cruise or race with new crewmwmbers, when I am going over the emergency equipment, the tool that I get questioned the most over are the enormous pair of bolt cutters I keep near the nav station. When asked what they are for, I always reply: "Why, to strip the rig
off the boat quickly in a dismasting, of course!"
I also make sure I have the mast base pinned to the step on my keel mounted mast. This prevents the mast base from whipping around inside the boat, potentially damaging the hull, bulkeads, and any crew below.
I know that here are some who would like to try and keep as much of the wrecked rig as possible in order to facilitate a jury rig of sorts for a return to port. You risk potentially increased damage to the hull, not to mention life and limb if you try to salvage the rig at sea. I feel that at the point of a dismasting, it is time to call it quits, light up the epirb
, and start the may-day broadcasts on the radio
