pchanez 0 Posted April 29, 2008 Share Posted April 29, 2008 Here we are ... First pictures of Thomas new foiler ... nothing to do with an 18' anymore, except the rig ... A big structure in tube, and under a hull from a M2 catamaran... Note that on the pictures, this hull is not there. Due to a strict deadlines, Thomas used 2 types of temporary hull : Pipes and then polystyrene/foam like hull (the white one) I'm sure Thomas will add some comment here in a near future (ie after the press conference today) Link to post Share on other sites

dougculnane 0 Posted April 29, 2008 Share Posted April 29, 2008 I am guessing here but I suspect that they want to play around with hulls to see what works best. Then the next version will have a hull that is used as a structural beam as well as flotation tank. Then the amount of tubes can be reduced a bit. The tubing on the boom is maybe too much. I would wrap some sail cloth round it for end plate stuff but then it would not look so radical. Carbon tube manafacturers are going to like the boat (or machine) though.

Small things make small explosions. I suggest you all put him on your ignore list now to make the world a better place. I do not want to speack for the guys that did this because I am only guessing, but it looks like they made a foiling frame and tested it with a basic hull and added the bags for safety to stop it totally sinking. With the results of this test they have a design hull size to design. This then gets strapped on and tested, or refined. If the concept works then you can make a structural hull and save a bit of weight later. Seams clever to me if this is right? Therefore give her a chance to grow up before you say she is ugly.

Chris 249 0 Posted April 29, 2008 Share Posted April 29, 2008 Fascinating, and pretty logical (as far as I know). So, in 5-10 years time, will we still talk about foilers as another sort of dinghy, or as something as different from dinghies as windsurfers and cats?

These guys have done a great job at jumping ahead but they can because they to not have to race against other boats. So they can afford to get the experiment wrong. Most class development is done in small steps so you have an edge to compete with not some mad experimental prototype that half works.

dougculnane 0 Posted April 29, 2008 Share Posted April 29, 2008 Sorry to SPAM this thread. Maybe you should put me on your ignore list too. Looking at the rig it is very interesting. The jib is small and the main has a huge head. I guess again that this is so that the size of the sail is big when you need power to get up on the foils. Then when up you can twist it off and depower. The sail becomes more like a windsurfer sail and modern moth sail where the top is floppy. How well this works I suspect depends on how well refined it is. Also looking at the rig the spinaker is becomming more and more redundant. How close are they from getting rid of it and all the weight and crap in the boat. You could then have a larger flatter jib that is low drag upwind and a bit geniker like downwind. You could also loose a crew member in light winds. I know this is not 18 rule complient but then nor is this machine. However since this machine will not go dramatically faster than tranditional 18s (or will it) maybe the rig is one development jump too far to soon? Link to post Share on other sites

MT14er 1 Posted April 29, 2008 Share Posted April 29, 2008 Maybe its just me, but I have some real doubts that a frame hull like that would actually be more aerodynamic than a simple low profile hull. With the apparent wind angle as forward as it is on fast boats, it looks like a forest of individual drag on all the tube. I may be totally wrong though. Also, whats to prevent this thing from going end over end every time the nose hits the water? Link to post Share on other sites

TeamFugu 26 Posted April 29, 2008 Share Posted April 29, 2008 Sweet flying machine. I with Doug Culnane on this one. I think the tubing will be a bit of drag but then you have to think of it as the guts of the structure and it doesn't have a skin on it yet. As was initially stated, the pictured floation and hull were foam and strapped on. Once installed, the hull will be there only for a bit of initial floatation and to help cut drag down. It will be a skin only and the current tubing is what really makes the machine work. There may be more drag issues to work out later but it looks promising. As for the rig, It is an 18 rig to cut down on time spent development and testing. It has become the state of the art in the current 18's and is primarily to cut down on drag at the top of the main and automatically depower with little drag as some have guessed. If the gennaker stays, I think it will become smaller, flatter and be more of a staysail than a spinnaker. These guys deserver a lot of kudos for going way out on a limb to try this on their own. My hat is off to you guys. Link to post Share on other sites
bgulari 7 Posted April 29, 2008 Share Posted April 29, 2008 I would agree that the aero drag has to be higher than if it was a enclosed shape.. if you disagree i encourage you to put mesh on your moth.

Steve Clark 1,015 Posted April 29, 2008 Share Posted April 29, 2008 Very cool project. Isn't it wonderfull that you can lace together elaborate structures out of carbon tubing? Completely changed my fabrication life about 20 years ago. At the risk of baiting the bears; I might point out that if this boat fits within the 25' long 14' wide box and sets not more than 300 square feet of sail, it would qualify as the C Class foiler Doug Lord has been ranting about. This is because the "hull" such as it is is infact a catamaran, or at least it seems to be two small hulls set right next to each other. This was the Fredo's suggestion that Doug rejected. So Thomas, any thought of limiting the range of the experiment and sailing as a Class C Catamaran? SHC Link to post Share on other sites

Lunada9 0 Posted April 29, 2008 Share Posted April 29, 2008 I'm not so sure that simply skinning the space frame would make this boat more aerodynamic. It all depends on the shape being described by the frame, itself, as to what the skin will yield for a surface. That would not necessarily be aerodynamically efficient. Perhaps a better way to keep it light and simple would be to use some tubing that is being suggested on a post over at Boatdesign.net. http://www.boatdesign.net/forums/showthrea...3513&page=4 "A little research on available structural material for their project would have led them to a truly innovative carbon solution called ISO-Truss for their tubing. I suspect that they would have saved weight, enhanced the aero component and significantly reduced any drag associated with waves and spray. Check it out here: http://www.isotruss.org/ Below is a shot of the tubing being used for the frame of a mountain bike." The post included this shot of a mountain bike made from the tubing.

Doug Lord 1,219 Posted April 29, 2008 Share Posted April 29, 2008 Most impressive, Thomas! Steve was right: it is(or could be) legal in the C Class-how do you think the two "hulls" work in comparison to a small single hull in building takeoff speed?. I'm most impressed by the forward foil position-seems like that will vastly help the pitch response of the boat. Probably the most important monofoiler innovation since the wand-assuming the balance is still good. Saw a while ago that the Arc 21 catamaran used a concept they call"shared lift" where the daggerboard was made smaller and moved forward of the mast. They said it worked well.... Again, you guys have truly done a 'revolutionary' boat -what a great job! Congratulations!! Link to post Share on other sites
EthanB 0 Posted April 29, 2008 Share Posted April 29, 2008 I like it -- the video is jaw-dropping. I wonder, however, if the designed hull (which they don't have yet) isn't too vestigial-- Even the best Moth sailors touch down during a tack.. . I'm thinking that in the interest of wave piercing and water shedding, it might be wise to look at catamaran design -- Infusion, Capricorn, A2, etc. Maybe in a later evolution, the hull (or hulls..?) can be simply a large lower beam, and upper trusses can be added to provide stiffness, trapezing racks, etc as necessary. But for now, nevermind my speculation. Good on them for making a very cool toy! Link to post Share on other sites

Lummux the Great 0 Posted April 29, 2008 Share Posted April 29, 2008 Ahh the age old question... monoque or spaceframe and skins... which is stronger for it's weight? Crunch the numbers.. If doug had crunched the numbers he may have found a trimaran configuration can carry more sail area per unit weight and per unit of wetted surface (I think actually having a surface to wet is a pretty good idea) monofoilers are cool, but they will occupy a nitch shared by windsurfers, kiteboards and crackpipes. A "peoples foiler" "monofoiler" is about as likely as a sex tape of ellen degeneres doing richard simmons turning up on you tube. Take Doug Lord, the dude is a fit as professional bowler. Could he work one of these carbon fiber monsters? That poor boat would see more ups and downs than a porn stars buttcrack. A peoples foiler has to be abled to be sailed by a people.... by a fatass basically. A slow, mushy, 12 big mac eating, forum troll has to be able to sail it. It has to be a tri.

SimonN 720 Posted April 29, 2008 Share Posted April 29, 2008 As Ethan so correctly points out, the biggest issue will be to sort out "touch down"! Look at the end of the video! It is suprising how much of the time a foiler is in the water, even if it is only a touch down and immediate lift off. I also have concerns about the bouyancy bags! How much drag are they adding! However, without them the boat would be at the bottom of the lake by now. I think it is interesting that they were only able to save 20kgs compared with an 18' skiff. I wonder if that includes the "hull skins". I love the way that DL has to latch onto something as being "probably the most important innovation....". He is probably unaware that others have tried moving the foil forward, including one that went to the bow. However, those were on single sailed boats and maybe the jib will help. However, the really interesting thing about foil position is that I don't think it will be very hard to move the main foil and therefore Thomas will be able to find the idea position, something that a more conventional boat cannot do without major surgery. Overall, it's an interesting concept, but it has a lot of questions still to answer. Link to post Share on other sites
Liquid 646 Posted April 30, 2008 Share Posted April 30, 2008 Interesting yacht that's for sure. Not a people's foiler, but a foiler for sure. The real question has already been asked: Is it faster? Also, if you eject the 'hulls' and the wind dies, what then? Link to post Share on other sites
Amati 1,852 Posted April 30, 2008 Share Posted April 30, 2008 As I was watching the video, did I see the machine rise up just a little while they were pushing it out? One of the guys does crack a smile....... Does the French aerospace industry have it's own Boeing Surplus? Like a CRIT Surplus? I bought some spectra tubes at Boeing Surplus that apparently weren't supposed to be sold (I found out later) once upon a time. $.50 a pound. Prepreg Kevlar $.75 a pound. A roll of prepreg spectra for $1.00 a pound. Titanium tubes that were impossible to cut, etc. There were some guys with french accents prowling around...... 'Bye the way, one of the commercial foiler companies (Windrider) was selling it's aluminum foil stock by the foot about a year ago- verticals, and horizontals (and their flaps). Nice aluminum pieces, and they offered to anodize them. I think they are too heavy for an IC rudder or centerboard, although if the hull was light enough, one of them might make an IC self righting. The Dr. down in Florida designed the foils. Or so the guys at the warehouse said. You too can build a foiler! Paul Link to post Share on other sites
cdc 0 Posted April 30, 2008 Share Posted April 30, 2008 Maybe the tube look is trying to state that if you foil, you don't need to float. A little bit like the windsurfer sinker boards were saying, if you plane, you don't need to float. Windsurfers moved away from that though. Link to post Share on other sites

SoCalSlacker 8 Posted April 30, 2008 Share Posted April 30, 2008 Something interesting is the two wands at angles. It seams like this would fly the boat a little higher upwind when rocked up and lower when flat which would be good? also moves wand wake away from foils. I guess the added drag of two wands down wind would be bad, maybe some way to gybe the wands would solve that. Link to post Share on other sites
Sailingkid 3 Posted April 30, 2008 Share Posted April 30, 2008 Its a good idea bit it looks different. I think you should just build a moth style hull, then build the wings foils etc onto that. That way you save on the windage from the pipes and it looks cool as well. I like the rig though. Link to post Share on other sites

Doug Lord 1,219 Posted April 30, 2008 Share Posted April 30, 2008 From Scuttlebutt this morning: NOT THE FAMILY BUICK Geneva, April 29, 2008 - The brand new sailing boat Mirabaud LX was presented to the media this morning at Société Nautique de Genève, in Switzerland. Supported by the Banque Mirabaud & Cie banquiers privés, this project is the result of Thomas Jundt's creativity and experience with highly competitive sailing boats. Aimed at flying on its hydrofoils, this 33-foot prototype has a very special characteristic: it has no hulls, although a marginal floatability remains, aimed at preventing the boat from sinking until it reaches flying speeds (approx 8 knots). Conceived around a structure of carbon fiber tubes, weighing only 330 pound, this boat is a concentrate of high technology. Every single element has been optimized in order to reduce the overall weight and allow it to fly on its foils as quickly as possible. As of today, it is the only "hull less" boat on earth. -- Full story and photos: http://www.sailingscuttlebutt.com/news/08/0429 ================= Technical datas : LOA : 10m Width (structure, without the ladders) : 1,8m Weight : 150 kg ( 25 kg for the foils) Surface of sails (upwind) : 32m2 Surface of sails (downwind) : 62m2 Link to post Share on other sites
punter 1 Posted April 30, 2008 Share Posted April 30, 2008 Shouldn't there be some "floating" aspect to this boat. Foiling gybes and tacks I believe can be difficult in a 11ft moth. But this thing is 30ft long and has 3 guys and a greater width. It may be fast in a straight line. But how many courses are a straight line? Only one I can think of is the world speed record and that is 500m. On a sailing course they would have to bang the corner everytime as changing direction would be dead slow and carbon pipes dragging through the water is a lot slower than a standard hull. Need more force to re-foil again to overcome this drag. Interesting concept, but to me extreme left field. Link to post Share on other sites
MT14er 1 Posted April 30, 2008 Share Posted April 30, 2008 The more I'm thinking about this the more I'm having trouble figuring out what the purpose of this boat is. It is a really cool concept, but what is it going to do? There is no practical way that you could race boats like this. Foils stall and you will fall out of the sky or touch down in a tack. Racing would just turn into a game of who can stay on the foils the longest. Tacking duels would be decided by which boat didn't sink. The aerodynamic drag of the frame structure will limit the boats top speed, so it probably won't be exceptionally fast in a strait line and the zero recovery aspect will make it really hard to push the limits of speed. The boat will be light so it will fly really early, which is cool, but that seems more like a novelty than anything else. It would be good to find out what the ultimate goal and purpose of this boat is. Link to post Share on other sites

If you read the daily sail article, the plan is to be able to strap differnet hulls to the bottom to experiment so there will be a hull. They just dont have it built yet. (an 8m cat hull is the current plan by the sounds of it). I am not sure they are going to see any weight savings as apparently this frame only saved 20KG's but it does allow easy hull develpment.

dougculnane 0 Posted April 30, 2008 Share Posted April 30, 2008 The more I'm thinking about this the more I'm having trouble figuring out what the purpose of this boat is.... How about Fun. Sailing in light winded lakes is boring and these guys are making it interesting. Should they take up motor racing for kicks on light winded days? Give it time and I am sure this will evolve and there could be the option to set up racing if there is a will to race them and boats to do so. Moths are racing on foils and it evolved to be far more tactical than in Lowriders due to the angles downwind and speed enableing you tr travel around the ocean looking for pressure. It takes time for these things to develop from straight line machines into racing craft, for a wide race of conditions. The only thing Ugly about this are the strap on polystyrene hulls and flotation bags. These will evolve into a proper hull that is easier on the eye. You guys are supposed to be Sailing Anarcists "Where the Status Quo Blows" Does this refer to the rock band or pushing the development of sailing. Maybe I do not understand this right, but I am supprised about the resistance to this concept, coming form various different quarters. What are you afraid of? Should this forum be "Where the Status Quo Rocks and we are quite happy about it so please lets keep it to 70s rock technologhy". BTW there is a nice article on The Daily sail about this: http://www.thedailysail.com/ISM/articles.n...025743B00320B9E titled "Beauty or the beast?"

t_huebs 24 Posted April 30, 2008 Share Posted April 30, 2008 ...It would be good to find out what the ultimate goal and purpose of this boat is. longy said it earlier. It seems to be a really efficient and relatively easy way to test concepts in reality, figure out what works, and what doesn't. This is by no means a finished product. As they refine things it might be interesting to see how the weight v drag issues play out with regard to handling. It just might be that they'll touch down less than the moths, but I have no idea. Pretty soon I think they will though. Huge points for building it and going out and trying things. This is the epitome of form follows function and in her own way she's gorgeous.

jfunk 4 Posted May 1, 2008 Share Posted May 1, 2008 I think the point that a few of you are missing and the press release emphasises is that the boat requires 8kn of speed to start foiling. My question is how does it get up to that 8kn speed. Certainly it won't on that strap on foam. If you look at the video the boat is supported by a tender which tows it up to speed. It's a fun concept and certainly a good frame for developing idea's, but as a stand alone boat at the moment, it doesn't work. I will be interested to see how proper strap on hulls affect it.

A moth has plenty on in 20+ knots but an 18 foiling in a blow...good luck. you my friend are nuts. Sure it would be faster in flat water and about 5knots after that they would be upside down.

the_skiff_devil 0 Posted May 1, 2008 Share Posted May 1, 2008 I think it'd be a bit more than upside down... if you watch the end of the video, one of the floats broke and they both snapped their straps after a very low speed noseover. Now think what would happen if it nosed over in some decent breeze unless they make the floats a bit more integral to the structure? My guess is that this thing will eventually wind up as a big carbon deposit on the bottom of Lake Geneva at some stage. Link to post Share on other sites

the_skiff_devil 0 Posted May 1, 2008 Share Posted May 1, 2008 The only hole in here is you doug ... an ARSEHOLE for thinking that anyone who thinks contrary to you is completely ignorant. I have a foiler and it flys and I have photographic proof of it Doug. How about you? I'm interested in this thing as far as it's an interesting solution to a high speed sailing craft, but I think that it is seriously flawed in that the entire concept is based upon the idea that it'll be flying constantly, which we all know isn't going to happen. These things are inherantly instable regardless of how good the wave sensing gear gets (even with your beloved manual control and midship wand...) there will always be the chance of the boat flying out of a wave and nosediving, which puts the structure under some really serious stress. And if these guys attach a 22' long cat hull, how can this thing still be your beloved 18' skiff of the future? Link to post Share on other sites

If the “Knockers” of this concept would only review a little history, they might just think before they open their mouths and stick their feet in! There was a comparable “structure” made from pieces of wood, wire, and canvas that only “worked” in a very limited way (in actuality with much less success towards the ultimate goals that the concept eventually attained than this craft) and that “craft” was the product of the fertile imaginations of the Wright brothers on the sands of Kitty hawk. It was primarily a prototype that was probably (definitely) ridiculed by many of the time with similar utterings like, “just what good is this thing anyway”. Look where that small step of innovation has led us to today? I would think that it would be prudent to wait and watch to see where this and other experiments with foiling lead before digging a big verbal hole of denial only having to bury yourself in at a later date Link to post Share on other sites
jfunk 4 Posted May 1, 2008 Share Posted May 1, 2008 Dagbar Foiling is not new technology, it has been in use for a long time. People aren't critical of this project, more expressing frustration at "I am the Lord" shouting down everyone and preventing constructive debate. There is a lot of skill here and people can see the limitations and merely point them out to aid creating a solution. Foiling has it's limitations, it's not the revolution "his arseclowness" would have you believe. It's an aside, but certainly an interesting one. Apart from Moths, none of the foilers presented so far are going to be quick around a course and if they are only straight line vessels, then sailboards and kites are faster. If you want real speed, keep your eye on Wot Rocket, from the rumours I have heard from her trials, she is going to smash 50kn. I can't imagine anyone would want the foilers to fail, every advance in this sport is cool, lets just keep a sense of perspective Link to post Share on other sites
