Mitch Booth's upwind gennaker...

Do you mean like the super-dooper swim suits that just had a dozen new World records seen or the guy who develops the bikes for the NZ team that saw Sarah Ulmer cut 3 seconds off her times and he says he has done it again?
Same bikes, boats, swimsuits for everyone please.....oh, that would mean we would all still be living in caves.

Rick I have taken photos off your sailing videos to get the ideas for my Tiger Shark and Taipan projects.

My reading of it is this. It is faster up wind in the light and the double slot keeps it almost as fast down wind...and as the wind comes up the boats start to get out of control down wind anyway so the speed will not be compromised after the wind gets high enough. So it is the intermediate wind and how big that window is that creates the end game.

Oh I don't know, I kind of want to find out who the best athlete is and I'm less interested in their equipment.

My cave has a flat screen and a beer fridge... cave living rules!

Equipment Rules:

The US trials were contentious because some swimmers could get the super suit while others could not... somewhat confounding the Who is the fastest swimmer competition.

I was hoping that they would just settle it like my mother would have back in the day.

All of this complaining... FINE! NOBODY wears a swim suit...

Would have made it a point to watch the trials then!

I wonder what the Tornado sailors are planing to demonstrate their feelings about ISAF's choice of equipment for the next games. Black sails?

How about a great big decal on the sail with ISAF inside of a red circle with the red stripe across it.
yanno, NO ISAF kinda like the big NO SMOKING signs.

Windy at Qingdao at the moment. Hope it lasts for the games and the gennaker stays in the bag.

(Again in my opinion it's one of those issues that ISAF just knows that members of the Tornado class will be pushing the rules and one of the reasons it does not like the Tornado class) ....
ISAF officials don't like those pushing the envelope? Like the world-class Olympic swimmers, track and field (etc.) competitors who continually discover fancy new drugs to be investigated and banned? Now superlight Yinglings? Who ever thought that light boats have an advantage? DUH!

If the multihulls in this week's light-air Chicago-Mac race had hooters they may have stayed much closer to the 90 footers. Yesterday I accidently met a slug racer who was returning home to Traverse City. They saw my 2003 Rick's Place/Hogsbreath T-shirt and asked what that and CABB was. I explained sadly about Rick's Place. 8^( Unprovoked, the fine gentleman then explained that catamarans aren't really sailboats, besides, they don't go upwind. And I had to reply

Yup- and they don't sink

.

I forgot I had this old pic of me learning how to sail screacher upwind back when I first got the Fboat, forgive the overtrimmed sail for I knew not what I did. Not that I know much more now, but then if it was easy, everyone would be sailing...

There is nothing new about this kind of sail, is there? It has been standard on big monohulls for many, many years. It's called a genoa jib. It is just relatively new on small multihulls. Right?

Its new on the Tornado and what it makes it interesting is that it shows up at the olympics I guess (and that not all teams have it).

Snuffing it seems to be a new twist.

Reg and Rob White had a bagable code zero on their Hurricane 6.5's about 15 years ago. This is nothing new.

Given certain hydrodynamic properties and analyzing the 'foil cross sctions'... Who'd you think would be faster men or women in the above scenario? <img src=

When do they have to decide which set of sails they will be used during the games?

Gill

Typically, measurement day is the day before a regatta begins...so all sails are declared and given an authorization stamp...but not sure how they run the Olympic event.

I would suppose one could see Captain James Cook as a sailor...just.
his observations of the Tahitian multis in his journals are interesting.

He saw them and very fast and maneuverable vessels. Strangely he did not get into any other ideas about

real

or not. Perhaps the chap meant that multis do not point....but we all know, it is not good enough to just point at something...at some stage one must get there, so who might be first?

I am often surprised by the inability of mono/multi to see the wood and take ideas from each other more quickly.
I notice the X40s furl and drop their reacher....why not do that as they will have already done the math?

I don't think they did any math. Over 400 square feet sail area one can't use a snuffer, so it is easier and faster to furl and drop.

I don't think they did any math. Over 400 square feet sail area one can't use a snuffer, so it is easier and faster to furl and drop.

400 square feet? that's tiny on a boat that big.... New boat design for a big sailing circus and nobody does any math....? Really, are you have a grumpy day?

Like I said, the Tornado might be a lot better off furling and dropping for windage alone....having said that, maybe the snuffer allows more variety in sail.

I think it's a matter of time. Snuffing a sail is pretty fast compared to furling, dropping, and getting it controlled somehow on the trampoline. When you have a huge sail, this is about your only option (and much easier on the sail) and most of these big boats have 6 or more people on board to handle it. On the Tornado, minimal fuss and speed are critical so they're probably better off snuffing it.

I would strongly disagree with this.

I raced the Mac on a boat with a Code Zero or basically a roller furling headsail that was designed for downind sailing, a hooter.

We were severely handicapped in dead down situations. We used every technique and angle that we could think of and were getting crushed by smaller boats (multis) that could sail lower angles and carry the apparent wind lower. We also gave up alot of distance and angle to leaners (monohulls) who would just put up a cloud of a spin pull the pole back and go nearly DFW.

The sail did have its window & conditions, but for pure downwind sailing I I would not want it as my ONLY option.

Re Korz comments: From the beach, website, and looking at weather reports it looked like light headwinds were present all of day 1, and it appeared that is when the big leaners got way ahead of the multi fleet. This suggested that proper Hooters (code 0) on a close reach would work to weather for multis.
On the water, the reality was?

That's banana boards vs hull lift... Tough call!

Extremely dependent on the water temperature.

Are we taking buoyancy into account?
