Fill them with Beer, Bourbon, Whisky Scotch, Pina Colada Mix, Marguerita Mix and Rum and Tequila and you will be the most popular girl on the race course. For a whole new reason besided your stunning good looks and your sterling personality. Heck, I'd probably follow you around, even if you Don't laugh at my jokes.

Speaking of Jokes......

An older man approached an attractive younger woman at a
shopping mall.

"Excuse me; I can't seem to find my wife. Can you talk to me for a couple of minutes?"

The woman, feeling a bit of compassion for the old fellow, said, "Of course, sir. Do you know where your wife might be?"

"I have no idea, but every time I talk to a woman with a chest like yours, she seems to appear out of nowhere."

I have devised a special diet to help with your goals… 1 pizza for breakfast, 1 pizza for lunch and an unsensible meal for dinner (like 12 bigmac’s, or 12 whoopers)

Thanks for the advice.
Breakfast and lunch sound okay, but I don't think I have ever been able to eat more than five Big Macs at one meal.

LOL!!!!

what's a "whooper" is that like a yooper from Michigan's Upper Peninsula?...or is it a whopper from BK? <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />

Wouter, this is VERY specially for you.

The boat is only sailing at about 12/15 knots in these images. So no, it is not throwing spray out the side. It did on occasion on that day but no photo. I include a photo of my Nacra sailing in less wind and going slower as you can see by my being inboard. Check the lee hulls of the two boats.
I have been checking my theories out with a proven boat designer and Olympic sailor. Oddly enough I take his opinion far more seriously than yours.

I make this pledge to you.

This boat will travel comfortably at 20 knots and will be tracked at 25knots over a measured distance or I will crash and burn trying.

I do not care what you think about what is erroneous and what is not.
There is a point at which all of your computer "virtual" world becomes nothing more than the twittering of a "knowitall".
I have made my own less than scientific observations and will put my actions where my mouth is.
You however will wait and watch for the opportunity to pull someone down.

This is one of those impossible to kill falsehoods that is debunked about once of twice a year. We've been over this topic about 10 times the last 7 years so do a search and learn what is really true.

Don't believe 80% of the sailing books out there. They all got it all wrong.

Wouter

You could be talking to Glenn Ashby for all I care. That boat is not planing in those pictures in the scientific sense and that is final.

And I don't care what you think of me.

And why does everybody convince himself that I'm a computer sailor ? Hell, I have 2 sailboats (1 homemade), 6 landyachts (partly homemade), 1 kite buggy, a quiver of stunt kites (home-made) and 1 surfboard. And I've been sailing since I'm 12 and have worked as a sailing instructor for 4 years. Even got a engineering grade in this field.

If you don't like me, then that is fine, but don't convinced yourself that I'm some knucklehead who doesn't know what he is talking about. You only make a fool of yourself.

Wouter

to delay pitchpoling at high speeds, (where the sail is trying to go faster than the hulls and the cat trips over the bows), you could add weight to the rear of the hulls

BUT, because of the problems mentioned already it would be better to simply cant the rig back as speeds increase, thereby increasing the distance between the bows and the sail's center of effort

which is exactly what windsurfers do already...

Ain't it the truth. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

THE ANSWER IS 42 (Not 42 knots or 42 MPH or 42 KMS just 42) everyone SHOULD know that!!! - it is the answer to everything - (watch out for the mice!)

Can't wait for your book, when do you plan to publish?

Can we have a catsailor poll/vote for the name?

We'll need potential titles for a poll/vote. I'll go first.

"Steve Fossett and Larry Ellison Can Eat My Shorts"

"The Wouter Identity"

"True Lies II"

"Born to be Riled"

"Wouter Wonka and the Reality Factory"

"Mien Truth"

I pick #1 <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

In my case, the answer is not very damn fast until it warms up.

Once you understand the principles, you can work it out for yourself.

Ah yes.... But the fun really starts once you MISunderstand the principles and work it out for everyone else <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

The head over heels moment is a product of the height of the center of effort(pushing point) above the drag (of the hulls) of the sails and the force of the sails. As such, the position of the sails fore and aft is irrelevant.
Windsurfers tilt the rig for various other reasons:
Their arms arn't long enough (the can only get their weight aft by pulling the sail with them)
They would rather have lift than de-power, so canting it over makes sense.
Canting it over lowers the center of effort

Wel let's see... Last year in the Hogs Breath over a measured 82 actual miles on long running tacks before jibeing to short running tacks we had a Marstrom 20 complete the course in 4 hrs 38 Mins and 6 seconds. Add 15%, my guess would be more, to the distance for the jibes and we see it traveled 94 miles in 278 minutes and 6 seonds. That means the average speed was over 20 miles per hour. This year if the forecast holds, we will see similar conditions with the winds at 13 - 14 mph out of the east. I will look for the first boat on Smathers Beach, Key West, around 3PM. If you do not like the 15% choose your own, In any way it is fast. Without the fudge factor, it means over 17 mph, average, for the same trip. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" /> Some say they saw over 25 at times on the GPS.
Have fun with this, The Nacras will be close by and maybe ahead.

The heavy-ish mast I have raked back sits back past the rear beam at the tip. This does provide a little lift and a lower centre of effort which is not so irrelevant but it pitches weight back meaning I have to get out less to provide righting moment and so makes the boat more stable at speed.
Cutting the rig down by 5 feet ( much lower center of effort) also means I have to drag far less useless metal and rag through the air as if you check the boats such as Tornadoes trying for these speeds it is clear they have far too much power and are too busy dumping in gusts to settle to boat properly.
