Posts: 26 Toronto | Yes all new boat Rolf, from top to bottom. New platform is a big difference on top of the new wing. The whole package is lighter, stiffer and more powerful than PL.
I cut it twice and its still too short

Posts: 6,049 Sebring, Florida. | About the wing...does the top half of the flap (rear)section operate independant of the bottom half? It looks exactly like an airplane wing, and of course an airplane wing has an aileron out there at the end, to control the roll axis. In this application it would help control the heal angle in a gust. Is that how you sheet it upwind in a gust?

There is the front #1,2 and the back or #3 as we call it.
The twist in #1 can be controled between the foot/bottom/boom, whatever you want to call it and the hounds 25' from the bottom. There is essentially a torsion rod inside the wing, the more we ease it out, the more the front twists. above the hounds, 25' plus, the wing does not twist in #1,2
As for #3, we can also control the twist between the base and the hounds and above. The control arm is integral to #3 at the 25 foot mark so it effects twist above and below that point.
Roll? Well we call it heel angle and yes we do use #3 twist to control the heeling force, or moment, on the boat. We don't adjust it by gust, we simply set it up right for the conditions on that leg of the course and forget about it. If there's a gust we simply ease the mainsheet (Angle of attack if you are stuck in aircraft mode of thinking).
The twist in #3 is opened up in big breeze as it reduces the load generated by the top part for the wing and in turn moves the heeling moment lower, closer to the axis of rotation for the boat, which allows us to carry more power for less heelinig moment, and in turn go faster.
Generally we set up twist for a leg and forget about it. After that everything is crew position and mainsheet, and of course good steering.

Posts: 26 Toronto | The event in Newport.
It's pretty casual. The boats leave this Sunday for Newport in the trailer and will start to be set up on Monday I would hope.
the rest of us arrive Monday eveninig and get to work on tuesday AM setting up the camp, wings and boats.
Venue is SAIL NEWPORT at Fort Adams State Park in Newport RI.
We will try to sail / race from Wednesday the 20th until Wednesday the 27th.
28th is tear down and pack day.
29th we travel back North.
As for the racing, I have no idea what the plan is so far. i would imagine we'll spend some time racing outside in the ocean and probably spend some time "indoors" in Naragansett bay where you ould see the action from the bridge I think.
Visitors are more than welcome on shore. On the water? Well we have a tender but it's full up already. So if you have a fast boat you could come watch the racing up close, or hang out near a mark and watch us go by every once in a while.
Sorry, that's all I know.
I would imagine we'll post updates at Sailing Anarchy as well as the week progresses.
go fast

Posts: 26 Toronto | Yes we had a fun time down there in Newport. too bad we could not sail over the weekend due to the Gale in progress.
We learned lots and steadily improved our speed over the course of the week.
In short, Cogito is beatable for sure. So now both teams will spend the winter making more mods to find more speed and power.
either way we were very happy with our new boat and PL VI for that matter, the young guns sailed the crap out of PL and even beat both new boats one day.
Fred will sell PL to someone who really wants to seriously race C-cats and can show thay have the will and budget to do so. He doesn't want to see a boat end up in a barn collecting dust at this point.
Home build plans? Well again think budget first. Cogito without paying for labour still had at least $ 50 K in materials in it. 4000 to 5000 hours of labour.
These days you could cut that down a bit if you know how to use CAD files and can order CNC or Water jet cut parts.
Yesterday I asked our designer how heavy Cedar strip and carbon hulls would be and he figured about 110 pounds a peice, which isn;t bad. Beams could be made from CST carbon tubes from Australia.
You could do a wing with 1/8 marine ply, a bunch of carbon, a whole herd of arrow shafts and you could make a half decent wing comparable to PL VI which is still not a bad boat.
If someone ponies up the dough, I will design you a good wing for a case of beer, OK 4 cases of beer and a bottle of scotch.
It can be done. you won;t beat us but you'll destroy a soft sail boat and never stop smiling.
Keep in mind, PL is 20 years old, and still is a competetive boat.
