too much string dangling for you mr. fuller.

Frank is probably the best designer of skiff style boats there's ever been - ok so he's an aussie but he's been responsible for: -

49er - olympic class
29er - 'junior' skiff class - used at the last ISAF worlds
B14 - fastest hiking skiff out there
Tasar - a design years ahead of his time.

he also wrote "High Performance Sailing" which is the seminal book on apparent wind sailing - you should read it , you might learn something..or at least more theory to beat basher over the head with...

Who in hell is Frank Bethwaite?

And what do Aussies know about anything other than to *"visit the
doctor" in any tactical situation.

And being Australian anything he did know would be the reverse of our
experience here in the U.K. so i wouldn't take anything he claims to
seriously.

Whatever happened to British sailing Gurus, like Eric Twiname, at least he
knew what he was talking about.

Aussies! The sum of what they know about sailing tactics can be written
on the back of postage stamp.



"*visit the doctor" means a forlorn tack out to one wing hoping for a
beneficial shift in windsurfing parlance, not sure if it means the same to
sailors.

Hi GRF, I know the theory too and it sounds very likely but Frank Bethwaite was the weather guru for the Australian Olympic Team for some years and and an aerodynamisist for Boeing or some other big corporation.  He has data on dozens of international competition venues personally collected for weeks in advance of the teams turning up and he claims there is nothing to substantiate the theory.

get the kiker on more than youwould have it for a reach and a tiny bit less than for normal upwind trim, hardens up the leach and stops it pumping over waves might calm the boat down a bit.
600 732, will call it Sticks and Stones when i get round to it.
Also International 14, 1318

Well close, but we've sort of been progressing together and they have
certainly dialed strong winds better than we have certainly.

Another point of sailing we struggle with.

If say Close Hauled we're at 40 degrees for arguments sake, we can foot
off to 45 degrees happily to get a better turn of speed.

At 90 degrees we can happily beam reach, but there is this almost a "no
go comfortably" point of sailing at say 55-60 degrees that we
occasionally come up against in a tight fetch, a course laid scewed, a
knaff tide or we've simply over cooked a spinnaker reach.

Either way it is beyond me to know what to do. The crew is in and out on
the wire can't stay balanced, the boat just doesn't seem to settle and
pitches above or below the point we want to sail.

And stupid Lasers simply cream past.

Very very very annoying.

Cold air descending trends clockwise ffs check any low pressure system.

Then if its a passing front certainly here in the U.K. wind trends from SW
- W - NW. This isn't based on data collection, this is thirty odd years of
localised windsurf race sailing factual based experienced.

I'd like to know who or what told you that.

No doubt some latter day University Graduate studying a degree in "The
counter point to the bleeding obvious"

upwind in a force 4-5, given probably lighter crew weight on their part.

Other than that we've been enjoying some success in the RS500, but only
in winds up to the top of a Bft 3-4 threshold, we're going to try the
smaller main which arrived yesterday, thinking it would be breezy
tonight.

Possible reasons:

1.   They are very good.

2.   You are crap.

Only joking!

When the wind gets up it becomes less about power and more about control. A 470 with its relatively small sail plan and long waterline length will always be easier to control, therefore perform well upwind in a blow. Add waves to the equation and you will struggle to hold them off (if the 470 is sailed well). 

Once around the corner things should change, your larger sail area and more versatile kite (you have to fly it) should come into its own and leave the 470 for dead (if the 500 is sailed well!)

I couldn't get a crew, and I simply can't really sail it with anyone else,
certainly not to a standard to take on Northern Masterminds.

I really wanted to go, if only to do the training weekend, but a bit sad
turning up on your own.

But I am looking forward to someone posting what the official "settings"
now are, we haven't a clue what we're doing about that part of the sailing
experience.

That was quick! Thanks for link to results. A decent turnout of 30 boats I see.

Where were you GRF?

Sorry to spoil the run of holiday photos , but I hear the RS500 nationals were dominated by Northern crews 

 1st Mike Saul & Sophie Hartley - Yorkshire Dales SC

2nd Wayne & Debs Fletcher Scaling Dam SC

Not seen the official results yet, but congratulations to them both.

Matt - might explain why the RS 500 at your club seemed so fast - they're very good!
