Deathroll v gybe

First, be damn sure you know if you're dealing with a death roll or a broach! The responses are damn near opposite. For the death roll, you're trying to keep from rolling back to windward, for the broach, you're trying to keep from rolling over to leeward. For both, overchoking the twing helps, as it depowers the kite a bit. For the deathroll, the ease of the guy, really can help, as can the pump on the main. In both cases, you're adding net vector pushing the center of effort to leeward. In many cases, the death role includes the driver having gotten too far to ddw, and the center of the kite being over
rotated out to windward, Having the driver, head up, away from DDW (or, as per the usual advice, getting under the belly of the sail) helps, but you gotta watch that you don't just slam into a broach. On a fair number of boats, the driver needs to anticpate the next response. It's easy to start to deathroll, head up, start to broach, and then roll right back into the killer deathroll. As a driver if you pump up away from DDW, be careful as you end the turn up to not overdo it. Expect that the boat may load up and try and head back to leeward, and be ready to pump the helm to steady out on the desired course. Thsi also applies to trimmers and people playing the guy. Don't let the kite turn into a giant Yo Yo, this makes the driver's job really hard. Also talk as you do things, so people know. If you're going to dump three feet of guy, I want the guys two boats over to know about it!

Death roll is a capsize to windward. This happens when flow develops off of the top of the leach of the main either because the vang is too soft or the boom is out too far. When the boat starts rocking overtrim the main big time. This will pull the leach back and stop the flow. Also keep the pole back and drive the boat back under the sails. Once your under control start easing the main again until she starts to rock and then trim in again. It is fastest just before you loose control.
