Jessica Rabbit orma 12m tri

[bushsailor 96]

Does anyone know anything about this boat.

She is one of the most impressive boats i have seen.

There is a youtube video showing 28knots in about 18knots of breeze 2 sail reaching

Maybe someone could attach the video.

Cheers

[k2mav 5]

Martin Fischer's design, I published some pics once he sent of her launch. He reported 40knots if I recall well.

[Trimariner 7]

Phillipe CosTe's new 40' Trimaran, Noumea, T foil rudders, curved foil floaTs, looks like a rockeT ship, will do The nexT NZ coasTal Classic!!! Look ouT Team V, cheers all.

[Trimariner 7]

Video on UTube, WOW.

[Clipper 47]

Link?

Great too see Phillipe has moved onto a new design, and this time a trimaran.

How can you have an ORMA 12m? I thought ORMA was a 60' class?

Bloody hell, time for a new boat, I have to stop looking at this shit, now I want one of these. Cheaper to run than a 60, but still good speeds achieved.

That will cost less than a new mast fuller

[Speng 8]

Yeah an ORMA is a 60 footer maybe they could've called it a Formula 40... Cool bit of kit but i reckon the real ORMAs will be unconcerned.

[Trevor B 76]

ORMA doesn't exist anymore, afaik.

[svendson 4]

Pedants, get out and get a life. Who gives a shit what an Orma is or isn't, this boat is sexy as hell. Anyone else have more info/photos/gossip?

[Keith 987]

I bet you will eventually see her in the Brisbane to Gladstone race, The Coastal Classic, and a few other New Caledonia, New Zealand, and Australian races.

 

Phillipes previous boat was the Crowther cat "Rogntudjuuu" and he always pushed her very hard, Raw Nerve was also a southern ocean 50 design, but i think both had mods done too them. I am sure there will be more than a few Ausi's and Kiwi's here that will be able to correct me if i am inaccurate.

That is exactly what I thought!!!!

[Trimariner 7]

Raw Nerve & RognaTujuu were SouThern Ocean 50's designed by Lock CrowTher. They were boTh sTreched To 55'To help wiTh noseing in. NoT sure if 888 in NZ was also sTreTched. Jessica RabbiT sure looks like a rockeT ship. Looking forward To some resulTs. CongraTulaTions Phillipe.

[Trimariner 7]

ORMA 60' class have finished and become The MOD One Design 70's. The formula 40 and 50 class's are sTill racing. The RabbiT is a formula 40 Tri.

[SCANAS 527]

Raw nerve's mast was taller, not sure if rognutujuu was stretched too? What happened to rognutujuu?

 

Vid of the tri looks good, be good to see her on different points of sail. User only posted the one video though.

[SCANAS 527]

Anyone know more specifics?

Raw Nerve now in Pittwater, NSW, called Windswept 2.

Rognutujuu is in Brisbane, Qld, being rebuilt - by Cruzey I believe

 

 

[DtM 582]

Windswept 2 has been without a mast for some time.

 

The owner says one is on order but who knows.

 

He uses it to cruise around Pittwater

[bushsailor 96]

Both raw nerve and rognutujuu were stretched out to 58 feet and modified. With the main beam so far forward and the shape of the beam if it hit a wave it would suck into the wave like a huge reverse foil. There were anti cav plates attached to the beams on Rogn........... but they had been removed before the Gladstone race when she capsized. That is what happened, beam caught a wave and pulled her down.

 

Obviously the current foil design is making huge improvements on boat speed in the right conditions.

That video is pretty amazing 28 knots steady in 18knots breeze reaching with a reef.

[mad 3,967]

very cool looking multi,

ORMA 60' class have finished and become The MOD One Design 70's. The formula 40 and 50 class's are sTill racing. The RabbiT is a formula 40 Tri.

Can't be many Formula 40's left anymore?? let alone class racing.

 

50's only had a few built as well.

 

ORMA 40 desribes it pretty well, be good to see it against a new 40 offshore Cat.

[AVID 1]

Now wouldn't it be great to see these two head to head. Bring on the ORMA 40 class I say

[mad 3,967]

Any others out there? For the investment in the design/plug/tooling you'd hope a few more of each will appear soon.

Hi,

 

I am Martin Fischer. I designed Jessica Rabbit together with Benoit Cabaret and John Levell. First of all I want to correct something. Further up in this discussion someone wrote that we had reported 40 knots of boat speed. That is not correct, so far our top speed has been 33.1 knots in about 19 knots of wind, two sail reaching on flat water. We have rather regular trade winds here in Noumea and while broad reaching we achieve regularily 30+ knots of boat speed.

 

We are still "discovering" the boat, but we are getting better at sailing her. Jessica Rabbit has - for the size of the boat - relatively large foils and she has T-rudders. This combination of big foils with T-rudders stabilises the boat very nicely. So far we never have had any critical nose dive situation or any kind of pitch instability.

 

We sailed the boat once with normal rudders in about the same conditions as on the video. The difference was quite dramatic. Broad reaching the boat was much less stable. Average speed was about 2 knots lower and top speed more than 3 knots lower.

 

Upwind the boat is pretty amazing for a 40-footer. Up to about 16 knots of wind we are doing 14 to 15 knots of boat speed, which is what we expected. But in 18 to 20 knots of wind the boat suddenly steps on her foils while sailing upwind and boat speed increases instantaneously from about 14.5 kts to 17.5 kts. This was achieved with a true wind angle of about 44 to 45 degres.

 

Most of the tooling of Jessica Rabbit is still available - so contact me (martin.ncl@gmail.com) or Philippe if you are interested.

 

cheers

Martin

Martin,

Thanks for posting here.

Could you post some specs rig size, sail area engine, any interior sailing weight etc.

There are plenty of people interested in industry leading multihulls.

Thanks

[coxcreek 5]

Glad to hear someone else explaining the advantages of T rudder stability (and foils too of course) - felt like I was shouting into a void and no one listened. Well, used to that..

Great to superb to brilliant boat Martin - you might even clean up the big V next Coastal Classic.

so how does she go in the light airs?

And what sort of average % faster than Split Endz?

Hi,

 

mast height above water line is 20 meters, maximum sail area upwind is about 130 m2, engine is about 30 hp. The maximum sailing weight including crew and equipement is 3.7 t. The interior is pretty simple, but nevertheless there is enough space for 6 people to sleep, there is a nav station and a simple kitchen. So the interior is much more comfortable and spacious than on an ORMA-60.

 

cheers

Hi,

 

thank you very much for your nice remarks. I don't think that we can clean up Vodafone. 60-foot is much bigger, but I think we can push them at least a bit.

so how does she go in the light airs?

And what sort of average % faster than Split Endz?

 

In light airs the boat is still quick - upwind close to wind speed - but a bit more sail area definitely would not do any harm. The boat was designed for the medium to fresh conditions we have here in New Caledonia. So she was not designed to be a light wind flyer. Nevertheless under gennaker we do close to twice the wind speed in 12 to 13 knots of wind.

 

As of Split Enz, so far we don't know because George - the owner of Split Enz - is sailing on Jessica Rabbit. But we all - including George - agree that Jessica is very significantly quicker than Split Enz.

 

cheers

Martin

Looking forward To seeing some InTeriors, layouT eTc. 6 bunks! JusT sounds beTTer & beTTer'er!!!

[Chapped 2]

Interesting, that this state of the art boat from some very well respected designers, has... full size amas for ocean style sailing.

 

If Martin is still reading, perhaps he could share with us just what kinds of design thinking went into the process of having full size amas and not the smaller, L'Hydroptere, style of ama solution?

[svendson 4]

To tack on a couple more questions:

 

Do you get any funny feedback on the helm with waves slapping with windward t-rudder?

 

Any thoughts on displacement limitations for this S foil with T/L rudder concept? Seems like reducing wetted surface and pitching is a fairly solid all around win, as long as the average boat speed is high enough for the foils to perform well enough to outdo their weight penalty.

[Doug Lord 1,219]

She sure looks good under sail, Martin-congratulations! Thread on boatdesign.net, too....

Hi,

 

to my knowledge basically all ocean going racing trimarans have full sized amas. In light airs you need the full sized amas to "lean on". Foils only provide less drag than a slender hull if the speed is beyond a certain threshold. This threshold varies of course from boat to boat but for a 40ft trimaran it is typically of the order of 14 kts to 18 kts. So in normal upwind sailing the amas produce less drag for the same amount of vertical force than foils.

Another reason for having full sized floats is safety. At high speed foils are fine if everything goes according to plan. But the foils may stall or even break and in such a case you are in big trouble if you don't have a hydrostatic fall back solution.

Hi,

 

there is no funny feedback at the helm. When you are steering at high speed you don't see the windward rudder - you better look at the waves and the leeward hull in those conditions - and it absolutely impossible to feel whether the windward rudder is in the air of in the water. This was in fact a concern when we designed the boat and the T-rudders are installed with a kick-up system. The idea was to take the windward rudder up on longer runs. Now after first tests it seems that this was not necessary.

 

The concept of foils with T-rudders should work on any boat as long as it is quick enough. To stabalise the longitudinal trim of a boat is only necessary if the foils produce enough vertical force to carry a very significant portion of the total weight of the boat. Significant means in this context at least 80%. So if the speed potential and the foil size can provide this ratio it makes sens to think about T-rudders.

 

cheers

Martin

30HP??!! I reckon you could get her foiling with that

 

What sort of systems do you have for controlling the foils' AoA etc?

Maybe you are right, I have to check the power of the engine.

 

For the AOA of the foils we have a hydraulic system to change the rake of the foils. If you change the rake of the foil you implicitly change also the load distribution along the curved foil and thus the effective dihedral angle. Hence if you increase rake this has the same effect as if you increased the dihedral (more horizontal).

 

cheers

Yes please, +1, Have 2 see Jessicas RabbiTs, ASAP. I Think I love you!!!

[Trimariner 7]

6 bunks, small but functional nav and galley! Thanks Martin. Great pics, will post later. Expensive but top finish and materials. excellent syndicate potential ?

God I love this boat. I would love to see more photos. What is the interior like?

 

I have been steering a Carsair 37 RS for two seasons of racing which has given me enough experience to appreciate all that went to this very special boat.

[Trimariner 7]

[Trimariner 7]

Not sure how to shrink file size but here is 2 to go on with!

I have had the pleasure of seeing Jessica Rabbit under sail in 20K plus of wind I when I was sailing my cruising boat to Noumea from Vanuatu in October. She was moving and I am pretty sure she was flying the main hull. I took some shaky pics, I need to find them. Afterwards when we docked in Noumea I saw her tied up. One of the most awesome boats I have seen in the flesh.

[B30 0]

Thanks. Love the carbon/kevlar chart table and sink!

[SCANAS 527]

Is J-Rabbit still going to do the Coastal Classic?

[huey 2 670]

This Beauty needs an update , is

any one going to use the moulds?

I would love to hear how things have been progressing

any more pictures or video

Thanks

[Trimariner 7]

Yes, whats happening? Coastal coming up again? She would have loved Airlie beach Race Week, and Magnetic Is and Hammo etc. Love to see her over this side of the ditch, Philipe??

[SCANAS 527]

That was coastal last year I asked about. From memory, she did race. Surprised no one else built one seems a lot of the hard yards had be done for someone else. Might not be cruisey enough for most people's liking.
