Re: Form an orderly queue - behind me please (NM).
In order that I dont forget anyone, and whilst no promises are implied, would all those in possesion of good health and a fearless mind (or in the absence of the second, enough Vallium), send me PM - I'll keep them and send some 'real emails' nearer the time. Only days with adequate wind are likely to meet the criteria!

Re: Pinching
Interesting - how much/at what point does this theory apply to my First 31.7? Spent most of the Regatta of Wales week pinching a bit and seemed to make most gains on the upwind legs, but maybe I could have done better?

Re: Pinching
Knowing nothing about the boat it's difficult to say, but I suspect you have a keel with a decent chord depth and a sufficiently rounded entry that the risk of stalling is much less. We would have been dead at Cowes this year - just too little wind most of the time, and with the fwd canard/rudder I'd be awfully reticent about poking in amongst the shallows too much (I'm considering one of those fancy FLS sounders for just this eventuality, and retracting it except when needed). In general, it doesnt hurt to bear away a smidge, build speed and then squeeze back high - but the sails will need to be trimmed through it.
In very light weather in tidal waters, one of my pet hobby horses is that people dont adjust the twist in the main for the different tacks. Usually (unless wind and tide are perfectly aligned) there will be a difference in AWS between the two tacks, simply due to the tidal component and this means that the twist is likely to be different. Too many people dont take account of this and are either depowered on one tack, or stalled on the other. The main trimmer really does need to call for either or both of kicker and backstay to be adjusted from tack to tack.

Re: Pinching
Ah! Your questions about FLS in Mobo earlier in the year suddenly make sense. Still haven't deployed mine (if you want to borrow it for tests, you're welcome).
If you fancy converting a mobo (fearless) to sailing, I'd love to take a trip as ballast!

Truthfully I think this is one of the most exciting subjects I have read on this forum. The design incorporates proven technology well tested in the Open 60 fleet scaled down to 40ft and I am sure off the wind it will absolutely fly.
Are you looking at the 05 OSTAR? (no-one I know calls it anything else)
Good for you in having the bottle to invest and good luck on the course. I am sure to see you around on the circuit and will come and say 'Hello'.

Re: Adrenalin incarnate
I have a suspicion she may be difficult to get to cat 0 ORC (or even maybe Cat 1). She is really designed as an inshore raceboat, not a deep offshore (although one did this years Transpac which is a longer race, but in more benign confitions than STAR). It is likely we will use PBO rigging, and I'm just a bit nervous about it's longevity, but the weight saving (aloft as well) is irresistible - but I'm not sure I would trust it offshore for a little while.
I do hope to do some short handed races, but in amongst it I have to run a bisiness (and at the moment a home and family), as well as find time to sail - which I have spectacularly failed to do this season.

Re: Adrenalin incarnate
PBO seems well proven these days and I wouldn't hesitate to replace the rod on AOD with PBO providing it's cost effective. I remember replacing the runners with Kevlar and I went through a 'should I shouldn't I' process but I have no regrets and now wouldn't consider using anything else.
PBO is widely used on the 50s and 60s and although in the early days they had problems I think these days it's pretty bullt proof.
hmm I can understand where you are coming from with the regs because when I planned the last OSTAR I had to glass in a bulkhead and then after the event rip it out again.
Not that I know anywhere near as much as you about your new boat I can recognise that it's clearly using a deal of the Open rule innovations like the canting keel and I would have thought that it would excel in the offshore stuff where you have a little more latitude in routes.
Great boat though and I am typing this a slightly lighter but non the less very evident shade of green

Re: Adrenalin incarnate
Thats really useful feedback. As a class (in California) the boats arent allowed it, but as an IRC (or whatever rating system we get next), it really doesnt matter.
As for cost effective - who knows, but if you can save about 150Kg of weight high up, then it has to be an improvement - but at what cost to the rating? Who can tell until you try it. The designer reckons it should be worth at least 12 seconds a mile (thats easy to apply to PHRF or IMS which are time on distance, but trickier to apply to IRC as Time on Time). 12 seconds represents about 4 or 5 boatlengths per mile which can be most significant.
On Sturday we sailed the current boat from Jersey to Lymington (Corbiere to Needles Bridge in 11.75 hours). As we went past Sark with 34 knots AWS at about 110 degrees, we reached for the S40 polars, and noted that rather than the 9 knots we were wringing out of the Trintella, this would be a 12 knot sail, later as the wind came further aft we should have been at 15. Yesss!

Ah, there we are, the <A target="_blank" HREF=http://www.santanasailboats.com/boats/schock40/schock40.htm>builders site</A> is back in the land of the living (onlike number 2 sons cat which lost an argument with a hooligan in car).
ther is a lovely shot of 3 of the boats at North Sails Race Week earlier this year somewhere on the site, but not too many of the boats really scorching in a breeze.
The class site has been off iar for some weeks - they obviously take their role seriously.
