I'm just about to prepare the gravitational speed accelerometer for another dash into the year 2297, and I will be doing some sociological research into why the Mandurah Mob is now populated by gorgeous young women? What happened to the middle aged bra wearing man that dominated the 2017 GPSTC, were there no equivalent men in 2297, In fact I had seen no men in 2297? Had the emasculation of men become so prevalent that evolutionary mutations were causing the penis to invert itself into a vagina, meaning that men no longer existed, had we all become women, and now reproduction was achieved through cloning..................the story continues.........

Apparently in the 23rd century holland becomes the hotspot for automated dykes.

Sorry Hardie, I will get back to my demoing so I can give the manufacturer some constructive criticism or the thumbs up.

Way back sometime in the distant past, when the Yellow Pages/Macquarie Innovation crew were planning their challenge on the World Speedsailing Record, I watched Lindsay Cunningham walk down the Sandy Point spit with a very long pole with tubes hanging of it at various levels. I followed in facination as he proceeded to erect it vertically at the waters edge and take wind readings at various levels. When quizzed, he said he needed to know the variation (at that place and in the specific wind direction and strength they needed) at various heights so he could calculate the twist that he needed to design and build into their wing sails.

This is an asymmetric wing. One way only.

It is also interesting that Yellow Pages had a much higher aspect wing and the newer Macquarie Innovation has a lower aspect wing and wider beam. Lower heeling moment and leverage trumped HA efficiency, even in this high tech craft.

YP held the World record for over 10 years! 1993 - 2004 , 46.52Knots.
MI finally cracked the 50 knots 500 (50.43) and set a C class world record of 50.08 after tide deduction. They did a peak speed of 54 knots on that run.
The outright record was already 50.57 knots, in the hands of kite boarder Alexandre Caizergues.

Opps. Am I in the wrong thread.

Oh no! Please Sir Hardy. No strike 3. I didn't realise..........

Phew. He has probably just dashed of the the 23'rd century on a scientific mission to investigate 'Lovelys'. Have I got away with it

That's not evolution, its the cold water effect. Just ask Firie about it after a winter session in his little rubber. Many years of this will have irreversible effects.

Interesting rabbit hole:

"After the success of this concept on YPE, a solid asymmetric wing was also designed for Macquarie Innovation. It is here that the two speed yachts differ most significantly to the naked eye. In order to increase the maximum available speed of Macquarie Innovation, more force was required out of the wing. This was achieved by altering the standard section profile of YPE and drastically reducing the aspect ratio of the rig. MI's rig is approx 7.5 m high and 3.4m wide. While there would be a loss in efficiency due to the greater "end loss" from the low aspect rig, this loss was easily compensated for by the reduction in overturning moment. This meant that Macquarie Innovation, when compared to YPE could generate significantly more force before it tipped over. This force was then utilised to drive the boat significantly faster. As a comparison, computer generated velocity prediction simulations predicted that YPE had a maximum top speed of around 49 knots in 19 knots of wind. In the same conditions, Macquarie Innovation should be capable of 58 knots. "

Glad they weren't reading this thread via time machine. Had a very high aspect ratio 8.2 about 15 years ago. Rigged on a 520 with a ton of extension. Sailed like crap given that I'm about 170cm tall.

Wow hardie that raises all sorts of interesting questions! Will the lovelies be eager to try the joys of natural selection, after their years of rather clinical and sterile designer gene clones.
If so were they able to help with your little problem? -------------------

Does the current tattooing fad evolve into multi coloured intricately designed people at birth?

Can't wait for your next report!

Yes, but no one knows anything about aerodynamics about from MW, because he flies Cessnas.

Just got back from my second trip to the 23rd century, and there were still people that couldn't let it go 280 years later, "the site is up on wingsails" thread had now reached page 21,234,987, people were still talking past each other, and it was very clear the descendants of previous generations had been taught to hate their tribal adversaries, as had been the case in all human history with tribal rivalries..................I couldn't be bothered with it back then and wasn't going to waste my time now, and began to introduce myself to the lovelies of the 23rd century Mandurah Mob, and i can say they were much more interesting and enjoyable than these old tribal hatreds

Hardie you great big tease, I've been dying to hear how you got on with the lovelies, if they wanted your body, and if they fixed it.
And all you come back with is some drivel about MW sails!!!!! How can you?

I have done 60 knots already, I use the same sail size from 20kn to 50kn wind speed.

You all believe me because I say so, right...?

Chris, flying plane is more of navigation and communication with ATC, knowing your present location and planning ahead. In flight school they give very compressed knowledge of everything. But building planes , starting from early childhood greatly contribute not only to knowledge of aerodynamics but to know how. This why I don't need to quote other peoples lines here, unlike you, I have my own opinion. But listen, this week I posted new CFD blog , 40 degrees AOA . You can learn from it, Who knows one day you might be able to express your own touts here, I will not criticize, promise. Enjoy. www.mwsails.com/single-post/2018/01/12/40-degrees-AOA-Hi-Load

I quote lines from other people because they are world-leading wing designers who have a lot more experience with wing building and design than you have, and unlike you they have won world titles and broken world records. They are proven winners and proven experts and you are extremely arrogant to claim that you are wrong just because you've built and flown some planes and are, by your own admission, a mediocre sailor.

I have expressed many of my own thoughts here. I'm very happy to admit that I can learn from people who have proven their expertise, but I'm not interesting in learning from people who sling **** but have not proven anything.

Having the confidence to think that others have got it wrong is the only way to move forwards and every application is different. Of course the person who thought the others were wrong will probably be more wrong more often than not but eventually one is right and its the only way to make change :) . Every idea is a good idea even if its wrong.

The aeroplane failed heaps of times before it worked. Infact almost everything failed before it worked. I think the current sails will be faster than this but a definitely wouldn't say don't try.

Interesting rabbit hole:

"After the success of this concept on YPE, a solid asymmetric wing was also designed for Macquarie Innovation. It is here that the two speed yachts differ most significantly to the naked eye. In order to increase the maximum available speed of Macquarie Innovation, more force was required out of the wing. This was achieved by altering the standard section profile of YPE and drastically reducing the aspect ratio of the rig. MI's rig is approx 7.5 m high and 3.4m wide. While there would be a loss in efficiency due to the greater "end loss" from the low aspect rig, this loss was easily compensated for by the reduction in overturning moment. This meant that Macquarie Innovation, when compared to YPE could generate significantly more force before it tipped over. This force was then utilised to drive the boat significantly faster. As a comparison, computer generated velocity prediction simulations predicted that YPE had a maximum top speed of around 49 knots in 19 knots of wind. In the same conditions, Macquarie Innovation should be capable of 58 knots. "

Glad they weren't reading this thread via time machine. Had a very high aspect ratio 8.2 about 15 years ago. Rigged on a 520 with a ton of extension. Sailed like crap given that I'm about 170cm tall.







Yes, but no one knows anything about aerodynamics about from MW, because he flies Cessnas.






Chris, flying plane is more of navigation and communication with ATC, knowing your present location and planning ahead. In flight school they give very compressed knowledge of everything. But building planes , starting from early childhood greatly contribute not only to knowledge of aerodynamics but to know how. This why I don't need to quote other peoples lines here, unlike you, I have my own opinion. But listen, this week I posted new CFD blog , 40 degrees AOA . You can learn from it, Who knows one day you might be able to express your own touts here, I will not criticize, promise. Enjoy. www.mwsails.com/single-post/2018/01/12/40-degrees-AOA-Hi-Load





I quote lines from other people because they are world-leading wing designers who have a lot more experience with wing building and design than you have, and unlike you they have won world titles and broken world records. They are proven winners and proven experts and you are extremely arrogant to claim that you are wrong just because you've built and flown some planes and are, by your own admission, a mediocre sailor.

I have expressed many of my own thoughts here. I'm very happy to admit that I can learn from people who have proven their expertise, but I'm not interesting in learning from people who sling **** but have not proven anything.




Having the confidence to think that others have got it wrong is the only way to move forwards and every application is different. Of course the person who thought the others were wrong will probably be more wrong more often than not but eventually one is right and its the only way to make change :) . Every idea is a good idea even if its wrong.



As Newton and Einstein pointed out, you don't move forward by ignoring what we already know, by insulting those who learned it, and by repeating a failed idea yet again.

Ok, do you have your own thouts?

A "thout"is an opinion you have on a given subject that you have little knowledge of... just guessing

Well if that's the case I've probably got plenty of them.

Agree!!! We all do and most of us have enough common sense to keep it to ourselves.
