Re: Multihull Popularity and Interesting Designs

How about this cruising cat? It doesn't appear to be holed, it's not a racer, it's a charter condo cat. It certainly wasn't safe for the sailors aboard even though it floated, they're missing.

What about this condo cat? The boat floated but the sailors are missing.

Amazing isnít it? Thatís a picture of the cat floating a year after it flipped. Now since you have about as much of a chance for a cruising cat to capsize as you do a monohull sink.....Those hulls look to be quite possibly livable and thatís a much easier target for rescuers to locate than a life raft.

Yes, I read about it when it happened. They went through a tropical cyclone, possibly fell of the boat when it capsized, could have lived on it for some amount of time but eventually perished, could have even been shortsighted enough to get in a life raft, who knows. I do love the fact that an overweight charter boat is able to float so high in the water, even after a year.

This is a very, very important point - against what I personally think is a serious misconception by people who have never sailed a cat.

So, Mark, correct me if I'm wrong, but let me lay out why I think this misconception about multihulls and speed can be deadly...

Your exchange above shows a very interesting notion about the kinds of speeds cruising cats "can achieve". As you point out - this is not the kind of speed you'd ever sustain. But more to the point, you really would not want to. It is here that capsize and pitchpole start to become a real possibility. Let's look at an example...

In post #18 above, I linked in a video of a new Lagoon 52 (undoubtedly a cruising cat) in fairly intense gale (F9+). Now, just the thumbnail for this video below shows the immediate problem...this boat is hitting speeds of 27+ knots!



But here is the more critical underlying problem in this scenario...



This is a new boat for this couple. But they seem to be clueless as to the danger they are slipping into. To them, they are "breaking speed records" (back to the exchange in the SN post above.). But in reality, look at what is happening to these bows as they are doing this...





In this sequence that port bow in under water for a full 4 seconds! Just insane.



And now BOTH hulls are digging in.

In the midst of all this you can see the woman with a very concerned look on her face. The guys seem oblivious. Her gut is telling her something - as is mine.

Now, I've personally never sailed a cruising cat. But I have sailed the BFS Flagship FIASCO!



And when I start seeing rooster tails coming off the bows, I slow the hell down. Immediately. Because you only have to go through a pitchpole or two to understand that its not something that you want to do.

This is why, as I've read many times and places, drogues/warps are a very good thing on multihulls. When you're stuffing the bows of a 52' footer, you don't just sit inside and talk about the records your breaking. You put out something to slow you the hell down. Otherwise instead of "breaking records" - you're simply on your way to becoming a statistic.

Mark, smj, PDQ, others who know - what say ye? Are these guys flirting with disaster as much as I think they are?

I don't know where you're trying to go with this...but what about these?



Hurricanes kill boats of all kinds. So stay away from them. What's new?

Re: Multihull Popularity and Interesting Designs

So ,the adrenaline rush ,just before you flip is what some seem to seak. They other end of wha th? is the charter cats in Thailand doing the goof on the reef. FRom our view point veranda we watch rented or skippered cats dance with rocks on the beach and anchor in secure crowds where it dries at low tide. Entertaining .

Re: Multihull Popularity and Interesting Designs

I dont normally look at these cruising links, but 27 knots in a Lagoon got my attention. It was hard to tell in the vid where everybody was when, I couldnt tell if they were surfing over 20 kn in auto pilot or in hand. 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.

Nope, just rough weather. Doesn't take much to make them invert.

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".
