4 Meter mono foiler project

I meant the sweep and shape of the lifting foil. tips etc.

 

Italics & serif versus sans serif. I get it!

 

Don't worry, I won't (unless I do )

 

====================
Gosh, Bistros but " the largest collection of data and testing to date has been done by" Dr. Sam Bradfield and his team. Bradfield invented the modern wand ( which is a midship wand,by the way) and has almost 20 years of data on production and experimental boats. He is also a friend of mine and taught me a whole lot about foils, wands, foil placement, foil sections etc. A great foiler pioneer!

 

Thank you for the PR puff, Doug. I just love being inflated via my midship wand. ;-)

 

Serious props to Dr. Bradfield regarding his pioneering work. I'm glad you have a friend & mentor as well. I'm sure you learned a lot about the state of the art during the tenure of his research. It would be interesting to have Dr. Bradfield (himself, not through anyone else's words) discuss the CURRENT state of the art, after he became familiar with the foiling boats of today. Time passes, and cumulative experimentation & refinement over time changes the baseline state of the art.

Regarding data collected, more sail powered foiling has been done in the last two years than all time before. Hundreds of foilers, racking up thousands of hours time have been on the water. Dr. Bradfield would have to been sailing 24x7x365 continuously for years to come close. Bora Gulari and Andrew McDougall spent many days tuning wands and trying different wand mechanisms prior to the past Moth worlds.

 

-----------------------------
Bradfield has built countless boats over his time as a foiling pioneer in addition to holding two world foiling speed records. He and his team DID spend 24x7x365 for over 20 years prior to 1990! How you could possibly think anybody alive has more hours testing/sailing than Bradfield and his team is beyond me. You quite obviously don't know what you're talking about. Bradfield improved a nearly 20 year old system designed by Philip Hansford and developed it for more than 10 years.
Keep in mind that Ilett copied Bradfields system and moved it to the bow with very little testing before selling boats with it. John felt ,at the time, that he had made an improvement to Bradfields system but freely admitted he had copied it. Then AMAC copied Ilett !
Some important details John missed- like the rigid planing wand and the REASON for its position.

Doug, take a deep breath for a minute and look at some of the numbers with which you seem to disagree.

Let's just say that there are some 300 foiling Moth-like boats out there in boatdom and that they have been out there for something like two years now.

Next, let's just say that the owners of these 300 boats are putting in, conservatively, something like 3 hours a week on the water, sailing fiddling and otherwise accumulating a vast body of collective knowledge regarding that type of foiling machine.

So, it goes something like this:

300 boats
150 sailing hours per annum
45,000 testing hours per year times two years = 90,000 hours of accumulated testing/sailing

You have indicated in this most recent post that Dr. Sam was going at it 24/7 for 20 years. I’ll bet that the only thing that Dr. Sam was doing for 24/7 during that period was breathing and experiencing peristaltic movements. For one thing, that is impossible, both physically, as well as in any realistic scheduling manner.

I get that you are just bubbling on all this. I also get that you are somewhat prone to extreme levels of exaggeration in order to prove your point and to also protect the good Doc in any way you can, but Doug... seriously, it did not happen like that, and you know it.

Not even NASA, in their all-out binge to get a dude on the moon went at it 24/7 and that was entirely funded as a priority project from the guts of the US government.

You simply have to get a grip, my man.

Now, once the Dr. Sam thing is returned to something like a believable ratio of hours spent, compared to hours physically available for any given time period, we can get to something like a good idea as to how all this testing stuff pans out. You can do the numbers if you like, but absolutely nobody with anything like a savvy understanding of how research projects are funded, as well as manned-up, will ever agree with you.

And then there's this problem... In the past, you've gone out of your way to fizz about how the whole Moth sales thing was just going through the roof with geometric sales numbers and that it was a revolution that was only just beginning. Yet, now you wish to discount the numbers of Moth sailors, who are also inadvertent testing monkeys, simply because the boat type is so new, virtually.

So, my man.... which is it? Is the Moth foiling explosion just really so much more sedate than you have previously indicated, or is the expression about the good Doctor just a wee bit overly enthusiastic in its expression? Unfortunately, on this particular set of parameters, you just don't get it both ways.

If you wish to insist that the Dr. Sam bit is truthful, then it becomes incumbent upon you to produce an unequivocally documented statement from the Doc as to what really went down.

So, we are back to you producing a set of proofs for wildly extravagant claims, which you have made in support of your overly exuberant fizzing.

And while you are at it, could you also produce the proofs for your foiling claims, with regards to that last boat you built? A set of high res digital images would do nicely as would a really crisp video clip with absolutely bulletproof veracity.

We all look forward to your developing interest in the form of supporting your claims as stated.

Good to hear you are still claiming to know more than people like Illet and AMac. If there has ever been any doubt about your lack of sanity this removes it.

Here's a hint: You are not Bradfield. While he may have had some success you have not. Your miserable attempt at a foiler did not fly. You continue to glom on to other people's projects, even when they don't want you claiming association. You claim others work as your own. You are an embarassment.

I believe you will go to your grave still yapping about your pile-o'-parts that will never be assembled, let alone get up on foils, let alone jump/re-enter successfully.

The only thing you are going to be remembered for is being the biggest kook ever on sailing bulletin boards. I guess that is something.

 

Don't forget this little nugget. (the moto grip flap control, with instructions on how to build it, we should be seeing them on everything soon)

Totally Awesome, Can you guys imagine what it must be like to sit at the helm of the "non-foiling turd-scow", you know, cruzin along at a blistering 5 knots, pull on the turbo lever, and feel the boat shutter beneath you as it slowly, slowly, slowly, starts going even slower because the flap is causing a ton of drag but not enough lift for the 3500 pound "turd-scow" to get out of the water,
What a rush.

Wa is lucky that his boat project cool enough that even your participation doesn't seem to keep it from being one of the hottest topics on this forum.

 

I would have to give style points if he had used these:

 

if you used the lock on version it would be even sweeter (get the lizard skins, they are better than those ODI branded ones)

 

So, was very busy today, so busy I couldn't get any boat construction "stuff" done. That's not to say nothing "boat related" happened. While "hanging" with my coworkers I came to the realization that I work with all the people that I would need for the perfect build team. I know a form/press builder (Shop foreman Scott Murphy), A crack mathematics/computer/electronics wiz (James Lindblom), a PR guy (Jacob Duncan), topnotch craftsman/finisher/daredevil (Cliff "Big Daddy" Wege), and a mad Russian vacuum bag/lamination specialist (Dmitri Panfilov). After some persuasion, each agreed to join my hydrofoil build team, which is good, because there is a ton of work, and every job will be overseen by a specialist as apposed to hacked by me (and I was going to get them to help anyway). We'll see how it works out, I know the boat will be better for it. Now that we have a PR guy, we can even start looking for a project sponsor.

I did get the numbers from Mike over at Aardvark, unfortunately the foils aren't big enough to lift this boat at a reasonable wind speed, so I'm going to have to go the homebuild route after all, oh well, whats the fun in buying pre-built stuff anyway?

Maybe I'll get some work done tomorrow.

I'm too old school for lock ons.

I have been a Yeti guy for 20+ years, starting with an ex-race team CroMo PRO FRO in the '80s. I'm on my third frameset, a classic ARC LT (the last one made). Anything Yeti gets style points from me.

Being from Boulder you must feel the same, although in my mind Yeti is a SoCal brand from the original John Parker days.

Great bikes. If only Specialized hadn't had that freak Ned Overend riding for them Yeti (Tomac!) would have won quite a few more races.

Have you thought of contacting Phil at Phils foils? He may be perfectly setup to do a set of foils to your exact design w/o too much cost. Design them,send to him and thats it-while you build the hull.
