15-20 knots cross-on, some head high sets, only me and a couple of kiters out... Where were you all?

That's the biggest surf I've been out in, good fun, although I did get rinsed a couple of times, and didn't manage even one gybe

Also that's the last time I listen to poledancer for rigging advice, he said to make it flatter, I was underpowered until I went in and let off the outhaul a bit. Perfectly powered then

hi nebbian,

i thought this excerpt from the neil pryde sail design page was very interesting...

In the same way that downhaul and luff curve will determine surface tension, outhaul is used to set the profile shape at the bottom and middle of the sail. Applying more outhaul will reduce (make flatter) the profile. A flatter profile has more control and less power, however it will also inhibit the release of the lower leach (which will make the sail less able to twist, and actually reduces the benefits of applying more outhaul!).
The amount of outhaul you apply needs to be a balance between a flat profile and allowing the lower leach to twist. As a guide, when you are using a sail with cambers, tube rod battens and higher surface tensions (such as a slalom sail), downhaul is the key to gaining control and wind range. Likewise, when using a sail with softer battens and less luff curve (a wave sail), use outhaul to enhance control and range.

do you mean the thing that holds the rig to the board?
