Can I watch for free?

No, but you can read about it on my blog.

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.........

In Aldi you can buy bottles of Port for $4, just saying.

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.

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

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.

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 think they already have automated dykes.

No you are thinking of the battery operated thing that looks like a finger, could be used to umm stop leaks.

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.

Another who "won't reply again." Just like big Arnie, you'll be back.

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.
