I'd still like to know where you got the statistics you posted earlier about sinking and inversion. And how meaningful they really were if you separated out the types of craft specifically of interest. But if you just pulled it from another site its likely that its just someone’s opinion doing the rounds. Like other invalid arguments that get endlessly circulated in the multi-hull ‘community’.
In the Queens Birthday storm in the early nineties none of the cats flipped but most of the monos either got knocked down or rolled.
This is a total fallacy as you should now be aware. The majority of the monos had no problem, go back and read this post; How do you feel about catamarans?
and read the posts afterwards. You can check the facts yourself looking at the links others provided. The pro multihull arguments based on this incident are typically disingenuous.
Another example would be on our first catamaran. We had a strong storm come in while at anchor with initial gusts of 90kts. When the storm came in a good percentage of the monos were knocked down to 90 degrees where our catamaran stayed anchored directly in the wind.
What sort of boats were knocked down? If you do a beam wind heeling study for bare poles in those sorts of conditions you'll get around 45 degrees for worst of the small light boats to around 15 degrees or better for the boats over 50 feet. At least for any sensible crusing design.
It’s not even sensible to suggest 90 degrees since the wind heeling moment is close to zero at that and the RM is maximum.
If you want sensible informative comparisons compare well found crusing boats comparable to the cat, I suggested before that will be a cruising monohull of at least 10 feet longer on the waterline.
........ What I'm saying is that a good seaworthy cat is just as seaworthy as a good seaworthy mono.
Based on what ? …… Under what conditions, for what boat, for what usage, at what time of year, with what rescue response? The statement is far too general. It's certainly not valid for every scenario there are several conditions in which cats are considerably more dangerous to be aboard ie the risk is extreme.
I’ll reiterate that there is a very disturbing trend of a high fatality rate for cats inverted in heavy weather, even close to rescue services.
It would be more sensible to adopt strategies that improve your chances of survival and take them seriously than try and spin the problems into obscurity with fudged statistics exaggerating benefits and downplayed risks. Multihull sites and marketers are rife with disingenuous arguments and hype. These are the ‘facts’ that get circulated and posted on threads like this.
