Are all multi hulls so noisy and unpredictable?

Finding a mono that could do do that would be really hard and awfully expensive, and she have compromises I would rather not agree to.

Cats, especially simple owner built custom cats, are great value for money if you consider all the requirements for cruising.

All good points. As far as the cost comparison goes, I think this is a sistership to your boat, right?

And if I remember correctly there were multiple different directions for the swell because of weather a long way to the south. And to be clear, I was not racing upwind, I was balancing comfort, speed and an expected 90 degree wind-shift in 48 hours when I would tack and make our northing. As it was I almost got it right, we tacked over with the wind-shift and were within about 30 miles of Flores when the wind shifted again and we turned on the engine and motor-sailed so we could get in that day.

It's not obvious, but the instrument repeater below the clock on the wall shows:
- TWA 70
- ​TWS 28kts
​- Speed 8 knots

And though I can't swear to the calibration of the instruments, those values matched my reading of the conditions and what I have in the log. The calibration of the particular wind instruments was generally pretty good upwind, but all over the place when sailing downwind with the spinnaker up.

The only thing I wanted to show was that it is possible to have a relatively comfortable ride in reasonably windy and wavy conditions in a cruising 48' catamaran heading in an upwind direction. Sorry if I inadvertently mislead anyone. Actually beating to windward in that would have been uncomfortable in any boat I have ever personally sailed on, monohull or catamaran. And I am also pretty sure that with less weight on board, or a smaller jib rather than the half furled all-round one we were using, or with a higher performance boat, you could have easily come up at least 10 degrees if not a lot more and still been comfortable. But that is conjecture.

Do you consider 70 TWA upwind?

It’s not downwind and the wind is forward of the beam so technically it’s gotta be upwind?

I guess, but it will be a long time to the windward mark!

Used to be part owner of a 2009 FP Lavezzi which is one of the nicer looking and better performing production cats. Nice boat but it did make a lot of noise under way. The starboard hull creaked like crazy and there was a lot of noise from the water rushing under the bridgedeck. Motion was rather jerky in most conditions with constant small accelerations and decelerations. At the end of a long passage I was exhausted and my wife often got sea sick. My much heavier monohull is way more comfortable underway. However, at anchor a catamaran is unbeatable.

Not really. This is an 11 metre Parallax designed about 15 years before mine. She has been extended and a cabin put on the open bridgedeck design. I really liked this design but Robon drew me a slightly bigger boat - larger hulls with more freeboard and payload. But this is the design that got me talking to Robin.

You've responded to this comment twice but you're wrong. Upwind in a seaway for most multis isn't quick unless they're running an engine

. You talk like all multis perform identically. That would be as silly as saying all monos can go upwind. There are a great many designs that work well upwind and and economical. Chamberlain, Crowther, Schionning, Schionning (not a duplication - there are two designers of that name), Oram, White, Lerouge, Hill, Tennant, Rapido, Outremer, Seawind (latter years), Carwadine, Kerr, Arber, to name some that spring to mind

Have you sailed any of those designs?


I do agree that There are a number of multis from three companies that are utter crap upwind, FP, Lagoon and Leopard. And they sell really well to your countrymen, so maybe that is what sailors in your part of the world want.

Compared to what? Other Fps and lagoons maybe, but not much else

Ok understood, thanks

I'll see your rubbish and raise you two rubbishes, I have forced plenty of monos up to windward when social racing, plenty, on a range of cats and tris, clearly not when sailing lagoons Fps Leopards newer Nautitech, but have done so on boats that were cheaper than the monos I was making luff up.

I raise another rubbish. You must be talking high tech multis and trimarans or you are racing against incomparable monos to your tri.

PS. Once upon a time, for a joke, I designed a motif for a T-shirt with 'Catsareforpoofters - Club President.' Crikey the cat fraternity didn't see the funny side of it and I nearly got linched. It was pre-touchy-feely era.

Not sure why you would be "linched" for that, but also not sure why anyone would find it funny. Is this something you regularly do, make up T-shirts with "insert type of transportation here"areforpoofters - Club President" for laughs? I'm sure you have them rolling in the aisles, so clever with the equating various groups to gay men. Did you really come up with that yourself? It's so original, you must be so proud of your cleverness!

Hilarious, says it all really. Why the hell are you hanging around us poofters in the Multihull Forum? You ready to come out of the closet.

Kay Riste mate! Lighten up. I think you just backed up my thoughts about multi sailors.
