The giant trimarans in this video are sick.

They are passing windsurfers and kite boarders like they are toys.
Anybody know how to make that a live link?? Thanks.
Scott,
Truely outrageous! They display a speed dial showing 29 to 30 ‘‘something’’, knots or MPH? Didn’t Roy go faster??
It is VERY instructive to see that kind of TRUE SPEED over the surface of the water. Thanks for the posting.
Yeah. And to think there are crazy folks (mostly Frenchmen) who sail those things single handedly around the world, around Cape Horn, dodging icebergs!
there are two boats even faster…
Yellow Pages
and
Macquarie Innovation…
But then no-one’s ever built a paulonia windsurfer before 
LOL!
Surfer Dave,
Love your ‘‘boxing cat’’ avitar. I can’t not smile at seeing it!
Swied… its visuals like that … that give people dreams about building things like that. Amazing and Ive watched it 6 times, the first 20 secs is the best.
I kinda enjoy watching 'foils perform…
SF.
Thanks for putting the sailing video up. First time I’ve seen the big tris riding on one outrigger hull.
I used to have a Hobie 20’ that was rigged for racing. It was so fast it was sometimes scary. The big danger that you need to be careful of is pitch poling. This when you are going full speed, and the bow of your leeward hull digs into an oncoming wave. The boat comes to a complete stop and you get pitched forward. It can be very dangerous – especially if you are clipped into the trapeze. I wonder if that is as much of a danger with the bigger multi hulls.
I have a long time friend (a boat builder) that has cruised the world. He says that almost any boat can pitch pole, given the right wind and sea conditions. The big multi hulls may be even more prone to that sort of mishap, because they tend to be sailed somewhat more agressivly. They have proven to be quite seaworthy. The ‘‘mishap’’ would likely be a result of too much sail (speed) for the conditions.
Even better than flying on one hull is flying on no hulls.
This tri “Hydroptere” is fitted with foils and has been clocked going 44 knots. Crazy Frenchmen!

Another good catamaran video is the one at www.gunboat.com. Check it out. It shows a 62’ foot luxury CRUISING catamaran with all amenities passing a state of the art 80’ stripped out racer (all the tris in the “everybody” vid are stripped out racers by the way).
In all all cases…hands on the sheets at all times!
ps. I you study the image at 1:39 I pretty sure those tris have canting masts- masts that tip to windward about 5 degrees. Don’t be confused by the angle of the headstay. YOu got to love the experimentation that goes on with those boats.
Just taking the video as it is, at 0.15 min theres a truckasaurus sized tri overtaking a windsurfer and kitesurfer.
The tri has a hull( s) with a basic design that is vertical, look at the leading edge…and the other two craft have horizontal hulls.
If you guess what I mean…
Is there maybe a secret in having hulls with this shape that provide this kind of direction and speed?
Sure, the tri has 1000 times the sail area of the kite but does it have 1000 times the surface area?
And despite the massive displacement, it still flogs the other two.
Maybe displacement volume and surface area is not as important as other elements?
Someones gotta know?
Still drooling over the video,
SF.
EDIT. And the video from gunboat.com proves it again, where its not the dispacement or length but the vertical surfaces of the hull that provide the drive.

I skippered for a company on Maui for ten years that sailed multihulls to and around Lanai, and to Molokini. We build two of the first ever epoxy sandwich composite boats certified by the USCG for charter, built them on Maui back in the mid to late 80s. One of those had a rotating wing mast, I had that boat showing 27kts on the meter one day on an around Lanai sail in the channel between Lanai and Molokai with about 25 passengers onboard. I was being watched over that day because when I got in we found that the shackle at the mast head had come apart and the pin was holding in just by pressure. My boss Randy was good friends with Joey Cabell and I got to sail with him on his boat. We refurbished a Woody Brown Waikiki beach cat that we took to Molokini for about 4yrs, but replaced it with a Cross trimaran eventually. That Woody Brown cat was not fast but had some surfer history I guess. http://www.sailtrilogy.com. Fast sailing on Multihulls is killer for sure. Some of the fast cat sailing I’ve done is almost as good as the best surfing experiences I’ve had especially since they were boats I helped build. But some of the stuff on these multihull videos is just insane.
Check out how much main is reefed in on your pics.

I know this has been posted here before but this is one of my favorite sailing video clips. This boat is SURFING!
And who could forget this one? At 39 seconds in I’m calling the bow 30’ above the water!
They set a non stop round the world record (which I believe has already been surpassed). I heard they had to strap themselves into their bunks like mummies. Still I doubt they slept very much in those conditions. I think it’d be like sleeping on a rollercoaster.
yeah! what a time for this thread when i’m right in the middle of it, living and breathing cowes week! some of those big tri’s kicking about at the mo but the stars of the show so far have to be the extreme 40 class. it’s impressive to see them steaming along up on one hull while everyone else is just bobbing along…
