Not sure if this has been reviewed previously but as I've got more and more fired up about foiling I'm re- assessing what sail suits best. For the past two season of slalom sailing I've used NP hellcats - no cams simple to rig and easy to gybe sails that for the average pension are as fast as most things you can buy

However after really getting into the foiling am considering getting NP V8s for next summer as they have two cams and from what am reading/ talking with other the feel is cammed sails suit foiling better....?

Discussing this with a Reg at windsurfing Perth he offered a trial of a RSX Convertible sail ( the Cross over foil/ slalom sail that is paired with the new one design RSX foil ready board) - 3 cams and full luff pocket very much like the full evo race sail

So in terms of the RSX Convertible sail.. tried it twice both days fairly light wind 10-15 knots only with the odd gust above that

Negatives
- feels quite heavy compared to the hellcats
- cam rotation in the 10-15 knots I sailed in on two sails is hard work and a really violent snap is required to get the sail rotated. Tried more boom length and varying downhaul but this persisted. Might be some cam spacers? or batton tension adjustment to rectify but as was a loan sail I didn't do anything in this regard

Positives
- beautiful thing to look at when rigged & easy enough to rig...despite the cams !
- Stable so so stable in gusts/ wind fluctuations huge difference to the no cam hellcats in this regard
- nice low down power and great top end when the odd gust came along
- because the sail is so well balanced and stable you can focus more trimming the board ...a good thing!

So in summary fairly convinced that cam sails are the go for foiling!

Thanks to Reg at windsurfing Perth (WSP) for the trial !!
