On the Gemini yahoo usergroup forum capsize has been a large topic of discussion for the past several weeks. A chartered daysailer capsized one on SF bay in 15kts of wind. Apparently he was running DDW and then tightened sail and turned hard to a beam reach just as a passing USN ships wake hit him. The combination of centrifical force of his hard turn, 15kts suddenly hitting the hardened sails and the wake tossed the boat.
Bottom line reefing is stated at 22kts, first reef to the jib, and a paper written by one of the usergroup members (with the background to do it) calculated that 28kts on the beam would in fact capsize the boat if no actions were taken to correct it.
Having said all that, I too would like to know what to do when going DDW and the wind builds, but I must turn to keep off the hard pointy things that keep getting in the way.
My current plan, having read all these and the yahoo usergroup posts, is to blow the jib, furl it, tighten the main as much as I can to slow down, pull up my centerboards (turn is then wider, less centrifical force, and no tendency to 'trip over' a board, it'll just slide to leeward instead). Then bring the boat slowly up into the wind, letting the main out as appropriate so it luffs as I turn.
The problem with all that is that, well, it's all that. Hardly an appropriate emergency plan - it would take too many hands to do, and far too much time for one guy (the usual full crew being me, myself and I). Best case is I'm running down wind at 9-10kts, and it would take me a full 3 minutes to get the jib in, centerboards up and main set to be ready to turn. Two minutes at 10 kts covers a lot of water - half a mile or so.
Incidently, dropping my engine (single on Gemini's lifted via a hydraulic leg) does put a 1kt drag on the boat, it might help. If I did that I'd most likely put it in reverse to slow me down even more.
Any catamaran folks out there with different ideas?
