Wrong Smack, no hurricane made the one on the west coast flip, just rough weather.

You love to obfuscate.

And it's great that it's floating high for the boat, not so good for the sailors. You sell false security when you sell "how high it floats".


Itís obvious you know nothing of the incident and even more obvious you know absolutely nothing about catamarans. Enjoy whatever you sail and I hope it treats you well.

Okay...here is a snippet from the article you yourself posted...

Quote:
Not much else is known at this point, other than the fact that the area near Cape Blanco was pummeled by 80 knot winds last week and that it's unlikely we will ever know exactly what happened or why the boat didn't seek shelter in the face of severe weather forecasts.
Look up 80 knots in the Beaufort Scale and tell me what you see.

Here is another snippet from another article that has a bit more detail...

Quote:
The morning of Dec. 11, the forecast issued by the National Weather Service for the coastal waters between Florence and Cape Blanco, the area north of Cat Shot’s last recorded position, included a storm warning, a warning about hazardous seas, and winds predicted from the south at 50 knots, with gusts to 65 knots. Wind waves were to reach 12 to 15 feet, running into a west swell of 19 feet.

“Waves with a long fetch from the south intersecting with large westerly swells can lead to wave super-positioning,” says Sven Nelaimischkies, meteorologist of the marine program at the Medford, Ore., weather station. “If this happens, 15-foot waves can build to 45 feet or more.”

A month earlier, on Nov. 12, the 440-foot container ship Westwood Pomona was hit by a rogue wave in the same waters, a little farther offshore. The Associated Press reported that a 70-foot wave smashed several windows of the command bridge, injured one crewman, and damaged the ship’s primary electronics, forcing it to put into Coos Bay, Ore., for repairs.
F10-11 winds - but absolutely monstrous waves.

Where exactly is the obfuscation? In any case, there is already a thread for the kind of capsize stuff you're posting. Why don't you go post it in there?

Doing those speeds in a cruising cat in autopilot would be pretty dumb, broaching at that speed could be catastrophic, a skilled helmsman might be able to pull a boat out of a broach at that speed, but an autopilot, not likely. Even in hand steering it looks really risky to me, dont think those lagoons were designed for planing speeds.
Watching through the video it appears they were on AP.

If I remember correctly they had a hired captain and crew with them. Doesn't mean they weren't on autopilot though.

Re: Multihull Popularity and Interesting Designs

I agree, it did look that way (like they were on auto). There was the young guy sitting at the nav station. I wonder if there might be a joystick or an autopilot control there with dodges, yaw controls, auto over ride etc. Not the same as having somebody at the wheel but maybe enough to pull the boat out of a broach. It would be interesting to know.

We were on autopilot all the time. It seems to work great...

Re: Multihull Popularity and Interesting Designs

Sure, but on autopilot can mean a lot of different things. Were they in the salon watching reruns of gilligans island on autopilot, or did they have someone standing by the over ride. Surfing at 27 knots in a cruising cat, they would be pretty foolish not to have somebody keeping a close eye on things, whether they were lucky enough to survive or not.

Re: Multihull Popularity and Interesting Designs

In one of these threads I remember our discussion about swept-back spreaders being a major problem for extended passages - not really "blue water" worthy.

Well, above I posted a couple of videos from the Distant Shores TV people who took a Bluewater 50 across the Atlantic...and pointed out how Discovery Yachts bought Bluewater Cats as well as Southerly Yachts (which this couple has long-sailed).

Now as I mentioned at that time, you can see some similarities in the boat types and usages here across this Discovery line (lifting keel monos for very shallow draft, etc.). And I think most would say that Southerly and Discovery yachts are definitely fit for crossing oceans. This Distant Shores couple certainly would - and have many, many times. But in watching some of their videos I came across something eye-catching...

Here is a still from one of their many Atlantic crossings on their Southerly 49 I believe...



Notice anything?

So, again, all these various dictums about what's good and bad for ocean crossings are FAR more blurred than has been traditionally painted on sailing forums. There are a hell of a lot of swept-back spreaders out there. I would just much prefer mine to be on a multi.
