2007 Update from Rick Perkins (1st Nats, 5th Worlds)

Note: If anyone else wishes to publish their 2007 settings please email me

Here are the settings for some of the faster sailors over 2006

Seems they are all pretty much the same ... looks like a bit of practice is the answer ...

Here are the figures for Rick Perkins new boat GBR225 >>>

Here are Stens figures/comments from March 2005

Rake is 7270mm - 7300mm I dont measure it very often too lazy. It is mainly based on the trim of the boat, too bow down I rake back ,if the transom drags I rake up.

Loose gauge readings Shrouds 28, Lowers 10 (Max 15 - Min 6) Forstay I never measured it.

Spreader sweepback 110mm to 120mm depending on rake

Mast heel is as far forward as it can be without touching the front pin.

My aim with all the settings to have a straight mast with the shrouds on 28 adjusting for any differnces with spreader angle and use the lowers to match the conditions that day

Here are the setting for the Top 5 at WYC - May 2004

Mast Rake was not measured but the current "standard" is 7280mm - 7310mm

Key

1) Measured from the side of the mast to the shroud
2) Stretch elastic between the shouds at the end of the spreaders and measure the distance to the mast track
3) Measured on a metric Loose gauge
4) The design of the mast foot has changed over the years but most people have it as far forward as possible (see pic, you can just see the bolt in hole 4))

* Note: Ian uses Ronstan rig adjusters

General Settings from Ovington Boats, this is a good starting point.

My rake is about 7410.  Most people were on 7470 in garda (or there abouts). 
Tensions seem similar - 28-30 on loos gauge on mains, 8-15 on lowers (condition dependent).

Update from Matt 12/1/2004
Rakes have settled at about 7300mm (from mast tip to lower skin of transom.
28-30 on loos gauge
Lowers between 8-15 depending on weights and wind

Simon Reynolds 24/6/2003 (5^th UK Nationals)
The present setting for GBR 113:
Shrouds, 5 holes down at the front, 28 tension on Supaspars gauge
Lowers, 5 holes down at front, 5 tension
Rake 7280mm to lower transom skin - thats No.8 hole on front chainplate with the mid length forestay for those who have them
Spreader deflection depth 85mm

Rick Perkins 6/8/2003 (8^th UK Nationals)
