Hi Everyone :)

Are these guys brave or crazy?

[amolitor]

A little bit of both? Where on earth did you find this picture, and have they really been flying the center hull since off the right hand side of the frame? or is that a centerboard wake where the skiier is?

I don't know enough about multihull performance to tell if these was any photoshop involved in this..

[Doug Lord]

No photoshop; I wrote to one of the people involved-it really happened and there is only one guy on the tri!

[amolitor]

Yeah, I found this:

http://www.my-photobox.com/seasee/agen/images/photogr3gra.jpg

which looks like it was taken a couple of seconds later. Did they dump the tri? I cannot look at either photo without mentally screaming 'let out the main you fool' but for all I know that's a stable configuration! The wake looks like an impending broach, or a controlled turn, dunno which in the link I just gave.

[Skippy]

The wake looks like an impending broach, or a controlled turn, dunno which in the link I just gave.amoliter, do you (or anyone) think they could be just hotdogging? The float doesn't seem to be toeing in yet. I assume they can go faster if they bring the hull down lower.

[amolitor]

Could be. I don't see them letting the main out, which I assume would be the right thing to do if you're about to lose it. I have a hard seeing how that's a stable posture, but what do I know? ;)

[Wynand N]

Hi Everyone :)

It is not only multi's that can fly.

Watch this guy make us mono's proud ;)

[Skippy]

Wynand, the other boat had 2 pics. Where's the other photo of this boat? Is the sail still visible? :)

[Doug Lord]

Things have changed within the "speed hieracrhy"-where multis were once king the lowly Moth(12.75' loa) has changed the face of reality by recently beating a whole fleet of 18'A class catamarans. A new Moth foiler was recently clocked at 19k in a 10-12k wind.

Doug, I'm still looking for the results for the time the Moth beat "a whole fleet of A Class". Can you steer me towards them?

I saw Rohan's boat last week, impressive.

[Doug Lord]

No, I'm going by what I was told ...There is some other confirmation on SA ,I think by astevo..
You can also go to the A class site in Au where in the inititial discussion on hydrofoils mention is made of A class boats being passed downwind by foiler Moths and that they are "catching up" upwind. Subsequent to that Rohan got the new boat and further refined his upwind technique..
I believe it ,Chris; these guys wouldn't make something like that up....

[Wynand N]

Hi Everyone :)

Here is some more on Moths. Nice photo of a pair of Moths flying. http://www.thedailysail.com/

Skippy, there was only the one photo.

[D'ARTOIS]

He Wynand!

That mono-picture that came next to the waterskiing tri is going down a breaker!
Was it a breaker or a freakwave from th 40's?

Nonetheless, fantastic pictures! :D

[yago]

... and everybody knows this one, but I thought it just belongs here ;-)

[Wynand N]

Hi Everyone :)

Then there are the mishaps :D

[D'ARTOIS]

Cavitation on the rudder, broaching an beng.....they didn't loos their mast, are they even lucky!

[CT 249]

It's the Sayer 38 "Belle", from Brisbane Australia, motoring out over the Wide Bay Bar and catching a nasty sea, IIRC.

[Doug Lord]

The last few years have been truly historic for development of small monofoilers. These boats are a technological leap forward and are groundbreaking in the history of sailing dinghies . They have done what no one since the start of sailing hydrofoils has done: sail on just two foils. The Moth class has led the way proving the practicality of bi-foil systems in racing.
Development in the International 14 Class was close on the heels of the Moth Class until the class voted only a short time ago to ban foils that would allow full flying; even so the "Bieker Foil" has become standard on race winning 14's.
The picture here is an historic one: it is the very first TWO PERSON bi foiler in the history of sailing! It is the first monohull foiler to EVER foil while flying a spinnaker and it is, of course, the very first I14 to fly! Interestingly, most Moths use a system similar to that of the Rave and SCAT multifoilers to control altitude-a wand senses altitude and "feedsback" to a flap on the main foil controlling height above water; NOT this boat: this boat is also the first MANUALLY controlled two person foiler. David Lugg controlled altitude by HAND: twisting the extension tiller!
See it below:

[K4s]

Hi Everyone :)

Are these guys brave or crazy?
Does the angle of the centre board in the main hull look right to you guys?Do they have two,one for each tack or what?
Seems to me that it should be an extension of the mast angle.

Im with you,dont know enough about photoshop but,That boat has massive acceleration,not many hi powered ski boats will pop a skier out of the water so fast that their wake just appears from nowhere.
Im dubious

[MikeJohns]

Hi Everyone :)

It is not only multi's that can fly.

Watch this guy make us mono's proud ;)

He's just been launched and dragged backwards by the wave that passed underneath, hope he got through it OK.

The helmsman would have been on adrenaline but has managed to hit the crest at the right angle. At the time of the photo if you look closely at the mainsail and the disturbed water I would say the boat is going astern being carried back by the crest !

So not so proud perhaps :)

[D'ARTOIS]

Nax photoshop, I've got something here, but he has lost his skier ( probably hooked of)

The tri is for sale - therefore the picure

[Skippy]

Quote K4s: Does the angle of the centre board in the main hull look right to you guys? ... Seems to me that it should be an extension of the mast angle.

Hey, I wasn't sure of this before, but given that last photo, you can see in that one anyway, the daggerboard is highly swept. Maybe that explains why the apparent angle in the first photo looks off.

[water addict]

Awesome pics! This thread got my heart going better than a pot of coffee! I'll have enough adrenalin now to make it the rest of the day.

[water addict]

PS, I thought about putting a pic of Murrelet on here, but that would be just too extreme.

JUST GREAT ;)

[Wynand N]

Some more :)

Even the little ones are fun

[SuperPiper]

Hey, a question about the 18' skiffs:

They are almost always pictured in that attitude, with the front 90% out of the water and the bow 1.5m above the transom. Is that a static condition? Or, do these craft bob along and the photographer just waits for this dramatic moment?

[Doug Lord]

I've seen a couple of videos of 18's in good wind and as best I can tell the photog waits and waits...
The only boat that really flies most of the time is the Moth foiler-so far.

[S.S. McClelland]

That mono flying is so sweet I had to put it as my background. Someday I want to try that, hope I make it, lol.

[hamid_amini320]

hi mr
i want the exprimental equation for wave resistance for sailing boat

[doesitfloat]

hi guys,
That center board is swept back on the big tri. Reason is they vary the amount of board in the water. When it not all the way down it sticks up above the deck. Most designs have the center board infront of the mast strait or slanted aft. ( ON performance Tri's, cruising tri could careless) Can't fit it behind the mast because it would hit the boom.

[D'ARTOIS]

Another one of Hydroptère................Racy and crazy......

[Wynand N]

How fast would you say she goes on this photo :?:

[doesitfloat]

18-22 Kts. No white caps, All apparent wind.

[Shife]

That photo was in a bunch of sailing mags about a year ago. Taken off the coast of France.




Hi Everyone :)

hi mr

Please? Thats the magic word that does wonders ;)

BTW, check your e-mail, what you want is there.

[mackid068]

NIce pictures. I have to say, regarding the first pic, those guys are pretty sound minded (not crazy at all). Depending on the wind and other factors, I would have to say that what they were doing wasn't too dangerous (depending on their experience, boat, water/wind conditions). I've seen, and I bet others have (as I have), righted a small cat from a list (not so great as in the pic, but a large amount at that).

[D'ARTOIS]

I thought you were on watch.........

[PowerTech]

That is some sick stuff.That makes me want to sail.When I was A kid My old man had a nice 25' C@C and we had Hobie cat and a laser But all that is gone now and them photos make me jones, what a rush.

[Wynand N]

Wynand where are you?
I thought you were on watch.........

In very deep trouble.........

[mackid068]

One thing to say...LOL!

[xarax]

There is extreme sailboat sailing and extreme weather sailing. "Only the brave" fight the elements, but in those conditions there is nobody else around to take pictures... :)

[skiff sailor]

what about skiffs there can go faster then most yachts

[tartanski]

OK I dont know if this is photoshopped or not but there is no reason to be , we all know Multihulls fly and that oyu only need around 16-18 knts to Ski, probably less with a wakeboard.

The mono hull foilers are great but just try taking a few lovely ladies out wth you I dmuch rather go with the Beach cat and a few friends ;-)

For speed freaks also chack out www.seaon.com these litte beauties will do 25kts easily.

[Doug Lord]

Geez, look at this-larger monofoilers will have even more capacity and leave multies in their wake just the same:

[Chris Ostlind]

Nice image, Doug. Would you say this Moth goes through a planing phase on its way to being fully supported on its foils?

When it's in that slender window with the boat partially supported by the foils and partially by the hull in its last throes of displacement mode, does that mean the boat is a planing design?

Just wonderin'

Chris

[Doug Lord]

Mothies claim the skinny foilless Moths plane but because of their high beam to length ratio and small inefficient planing area planing doesn't begin 'til around 15k. Foilers take off much earlier than that ....

[tamkvaitis]

All these boats are extreamly fast and maneuvraable, but what are they doing then storm struks? what king of performance does these boats have in wavy seas? hidrofails are insuficient then boat is sailing slow..can sailboat sail fast when it hits a wave? No..That is the most extream offshore sailboat????

[chandler]

Till it flops over on it's back and everyone drowns

[Doug Lord]

You mean from planing, flying a Moth or going fast in a 60' multi?

[chandler]

Going fast in heavy weather in a multi. Is that picture of a moth real? I figured it must have enhanced! If that's real I gotta get one of those!

[Doug Lord]

Chandler, it's real and was taken in Singapore. Mark Robinson was giving kids rides, if I remember correctly, as part of some other event. Shows that you don't have to be a total lightweight to foil!

[Sander Rave]

Hi Guys,

Don't forget to check the movies on the site of hydroptere...

[h_zwakenberg]

Hi Everyone :)

It is not only multi's that can fly.

Watch this guy make us mono's proud ;)


Did that fishing line survive? :)

[mfqrdf]

You may have all seen this elsewhere, but this seems like the right thread for it.

VOR Team ABN Amro did some wakeboarding behind their boat before Leg 1. Pretty sweet idea, and its a monohull

http://team.abnamro.com/web/show/id=92790

[Sander Rave]

These engineers did a good job designing everything to the limits... But what happens if you go over the expected limits? Nice example :-)\\http://www.macquarie.com.au/speedsailing.htm

[D'ARTOIS]

So you thought that only Moth's could fly?

[D'ARTOIS]

ABN-AMRO tried it too!
