Let's not confuse debate with a shitfight. Debate is good - it allows those with opposite views to state their opinions and defend their theses in an open forum. Our parliamentary system is supposedly based on the assumption that the truth will eventually be revealed by debate. And where there is no clear truth, then at least those who participate or spectate will increase their knowledge about the subject.
Bryan - I don't understand your second link; it seems to support my argument, not yours. For instance:
QUOTE"The bump in the Mira's stability curve shows, quite dramatically, how much extra large angle stability can be gained. Also shown is the well known curve from the 1979 Fastnet Race
report of the 30 ft Grymalkin, which capsized in the race
and stayed inverted for several minutes with the result that several crew lost
their lives. Since Gymalkin and Mira have very similar displacements, sail areas and waterline lengths, a direct comparison of their stabilities is reasonable. As you can see, the Mira has considerably more dynamic stability (the area under the curve is obviously more) while its static stability is only less than Grymalkin's at over 70 degrees or more. From practical experience we know that it is virtually impossible to heel a cat to this sort of angle, so I would always prefer to be in a cat than in a monohull
This graph also shows that a Mira is stable to about 95 degrees of heel (depending on loading), whereas many offshore
monohulls are only stable to about 105 degrees. The recent race results (Vende Globe, Around Alone etc) as well as cruiser disasters have shown that its not only multihulls that have stability problems.
Before concluding this series of articles I must mention a bit of a cross over between theory and practice.
Some years ago the Wolfson Unit at Southampton
University conducted some model tests in their wave tank of both a power cat and a conventional deep V power boat
to see which was the more stable in waves. People accept that a modern powerboat, like a Princess or Bayliner does not capsize
, yet the test showed how EASY it was for a model powerboat to get rolled over by even relatively small waves. In comparison, NOTHING the Wolfson Unit could do would make the powercat capsize! Believe me, they tried everything!"UNQUOTE
Let's summarize here - monohull capsizes killing several crew and power multi model could not be made to capsize in a wave tank. Your point again was what?
Next point - I wouldn't base choosing a boat for circumnavigating based on the insurance
The point regarding crew fatigue - I would presume from what I've read about them, that sailing in a cat is not so fatiguing. Whereas being heeled over for a couple of weeks on a cross pacific slog would be very tiring. Now you're so tired by the time you get within landfall that you run aground on a reef and watch your family
perish. I give my family
better odds on the overturned cat thank you.
