==========================I think the complete quote was " Sail upwind better than an equivalent boat without foils" I may be proved wrong one day but based on Jundt's 18 and the big M, I do not think so yet.
Here are three of Phil S quotes on this subject:
1)That 49er is about to make a big splash, maybe damage something big and possibly hurt people in the process. It might be getting lift momentarilly but it is not flying even by the standards of the Wright brothers on their first flight. No wonder most of us had never heard of the experiment or seen the pictures. (Show me a video of it going upwind in 10kts at better VMG than another good 49er and I might change my opinion)
Why do people fantacize about foiling all these big boats? Is its because the moths do it so well at it? Maybe they should look at what makes foiling moths successful. The trend is smaller, simpler and lighter with easilly depowered rigs, not bigger, heavier, more complex and more cumbersome in the water, out of the water and most significanly launching and retrieving. These same things made moths very fast for their size long before foiling hit the scene.
No matter how much enthusiasm there is posted by one zealot and many more uninformed speculators, the evidence so far is that it will be a long time before another class will get the success from foiling now being exhibited by the Moths.
2) Weight is critical for foiling. The people who go well are all under 75kg, better if under 70kg. I am 85kg and need 15kts to go faster round the course on foils than I do wihout. In light winds with foils I am so slow when the light people with smaller foils are still staying up there with the non foiling boats.
Consequently I believe there is no benefit in fitting foils to any boat bigger and heavier than a moth. If the boat weighs 50kg instead of 30 it will just need more wind before there is adequate power to overcome the imersed foil+hull drag and be able to take off. It might foil nicely with 20 kt winds but will be extremely slow in lighter winds. Building bigger foils to carry the weight only increases the drag at low speeds and makes it all worse.
So I see the proposed 50kg narrow International Canoe without foils as the best option for those people who are too big to race a foiling moth. Foils would not work well enough in a wide range of winds.

3) BUT DOUG THERE ARE NO PHOTOS OF ANYTHING OTHER THAN MOTHS FOILING TO WINDWARD.(2006)

Deleting your post and reposting in an hour later doesn't suddenly make it right Dougie.
Doug, stop fishing for a patent idea.Nothing here. Its all been done, tested, and proven unworkable. It took 5 years of experimentation before foiling moths were really viable and in that time the Iletts and Burville in Perth plus Wardi and my household in Sydney at least but also lots of others around the world, tried an enormous range of ideas and it was only really when John and Garth tested the first bow wand system that it started to come together as a viable set up. Subsequent experiments have proven no better.Believe me as one who has tried manual control and several poor auto systems, what we are all using now is the best out of a big bag of tricks from some pretty cleaver and inovative experimenters, all of whom prefer to build, get wet and test, and not just brouse the WWW.
I'm definitely in the running on #1, with strong potential in group 2.There should be Moth Worlds awards:That should be worked into the regatta T-shirt for the worlds. Maybe even add a foil beanie.Is anybody making a "I foiled before DL" t-shirt? For those of us that foiled on a moth before DL has ever foiled?
- The aeroSKIFF Memorial - for the most unlikely boat that is witnessed attempting to foil during the event
- The Oh Lordy! Award - for the most complicated control system that fails to work as intended
- The "Duggie" - for the most gravity-challenged person who gets a Moth up on foils during the regatta
Just some random thoughts.

Canting keels will change the world of sailing as we know it!!!!!Paraphrased quote by Doug Lord three years ago. So far, the only impact that canting keels have had on the world of sailing is precisely the same as it was when he made the comment. Racing boats and what... two weasel attempts to put them on non-racers that have been virtually ignored by the buying public.
Yep, Doug, you certainly got that one right. Changing the world of sailing as we know it...
More than three years ago, by Doug Lord... Bi-foil technology will sweep the sailing world and establish new realms of sailing performance!!!
Well, Douglas, I think that any reasonable man would very clearly say that bi-foilers have not swept the sailing world. They are being sold to a collection of those interested in the potential, but the larger sailing world still views the whole thing as a novelty and very seriously not for their tastes. What do you want to bet that the lowly O'penBIC has sold four times as many boats into the market place than the total of foiling craft? Hell, the Laser is most likely still outselling foilers and how old is that design?
We're not exactly seeing the big broom, Douglas. Where is the power in your ability to predict?
There's more Dougie, there's lots more... shall I go on?
Geeeezus, DL, get your fat butt out to the garage and produce something that shows that you have even a tiny inkling of what you spew, day in and day out.
Who's got the photoshop skills to put a Moth Monkey® in one of Bora's pics?
Please dont quote doug, i'm ignoring him and this way he slips through the net. I just log in to read all the insults and see how long it takes me to work out what the theme of his latest rant is about.DougA manual system for a singlehander will require intelligent design but moreover tons of practice but sooner or later I bet it will prove itself in the Moth class.
Why dont you build a Moth and show all these people how it is done?
I have seen Moths and apart from the foils material cost and labour would be far lower than any other boat so its affordable and you could buy a rig off the shelf so with your "intelligent foil design" you should be way faster and probably dont need a Rohan for your boat to win.
A self proclaimed expert on foils would relish the challenge of beating all others in the premier foiling class and surely this would raise your profile on the WWW.
Douggie in life you are either pushing it or you are pulling it and we know what you are doing.
=============Doug
I have tried to keep out of your threads of late because you contribute nothing of value and repeat the same stuff, over and over. However, there are times that you are such an arse that comment is needed.
You don't seem to realise that most things come down to credibility. Somebody like Phil has it. You do not. Phil has it because he has built more foilers and foils than all but a few professionals. He has tried more ideas than probably anybody else and best of all, it is documented and there are photos. Many of us have seen him foiling. Yet you tell us that he has no credibility.
DougSimon, that is not true: it is precisely because he does have credibility that his comments about manual control are so shortsighted. That is backed up by HIS OWN WORDS regarding a foiler like Mirabaud doing what it does: he specifically said it was not possible!!! So when a Phil Stevenson says manual control has been tried and found impossible pardon me if I'm just a little skeptical. Phil has great credibility in sailing but his forecasts of what is possible with the new bi-foil technology have, unfortunately, been dead wrong. And it is a shame when someone with Phils credibility makes a statement like "no foiler bigger than a Moth will ever foil" or "manual control has been tried and found to be impossible". I mean it is damned unfortunate and it is hoped that the true innovators will pay no attention whatsoever. Which is just another reason why Mirabauds experiments with manual control are so significant.

Some people are willing to admit they were wrong. Until Phil stands by his older words,1) you have no business trying to discredit Phil with them
What is clear - and what you still don't get - 2)is that your hostiility in the online realm guarantees that any "success" you might have in building a People's Foiler or a "Trapwing skiff" will result in it being shunned by the very community you want to sell it into.
1) Discredit Phil?! I'm afraid you're incorrect: I am genuinely sad that a man of Phils capability would have made the comments he made in 2006 in response to an individual on the Moth forum asking about the potential of bi-foil technology on larger boats. Those comments were wrong and unfortunately,since they came from Phil, may have discouraged someone from experimenting in an area that Thomas Jundt has proven was worthwhile.
And now, here in 2009 on this forum, Phil repeats himself with comments about manual altitude control that are designed to squelch any interest whatsoever in the idea-in the same manner as the comments in 2006 were designed to squelch ANY INTEREST BY ANYBODY in larger foilers than a Moth.
There is no intention to discredit more like amazed shock, disbelief and profound sadness and disappointment.

2) Hostility!!?? Have you every believed in anything enough to study everything ever written about it from any source you could find? Have you ever done any development work that resulted in a new boat or new system being created from scratch? Well I have and I have developed opinions that I can usually backup and a huge database of foiling information from design, building to sailing. That doesn't mean I know everything but it does mean I'm constantly trying to learn and understand development potential in foiling as thoroughly as humanly possible. What it does mean is that when I hear(read) someone-anyone-making a comment that I know to be false or misleading I'm going to speakup -and I'll probably present information from my database to back up what I'm saying. What it does mean is that if God herself said:" manual altitude control of a foiler is impossible" I'd look up other comments she has made in the past to see what her history is on the subject of foiling innovation-and then ask:why? Thats not hostility- it is a desire to see a subject rigorously discussed by well informed people who can defend their position. Only by that kind of intelligent discussion can anything be learned. Calling that hostility is way off base.
It is not wired into my brain to accept ANYONE saying a thing can't be done when my study indicates that there is -at least- a chance can it be.
I'm telling you. DON'T TAKE MY WORD FOR IT.Doug Lord said:[2) Hostility!!?? Have you every believed in anything enough to study everything ever written about it from any source you could find?
