Used a 6.7 NP RS Slalom MkII yesterday generously given by Sam at WSS.
Straight out of the box it was a great sail. easy to rig, light & soft feeling on the water.
Absolute perfection to rotate every time and just so easy to use. Great acceleration, great top end and easy to gybe.
Gotta be pleased with a PB on a AB+ 90 of 34.4. Never even looked like being over powered and it was as gusty as ever.
If you want a sail that is easy to use for GPS sailing and just keeps on going quicker & quicker give one a go, you will definitely be wrapped.

The Mk 11 was actually faster than the first lot of the new RS Racing sails.

Quote from Kevin Ozee NP Maui;

Aloha,

The racers are testing RSS MKII sails against RS Racing sails in slalom sizes - and, yes, the MKII sails are faster. But, not as fast as the new RS Racing slalom sizes...

The prototype sails I've used just feel lighter and more stable - easier to go fast, so you can push them harder for better top speed.

Pushed mine to over 36 knots on monday arvo, was so light in my hands i didn't believe my gps when i finished my run

Larko invented the dark side you fool, How long have you been around?!!! He can do things with nostrils and condoms that defy sanity...oops I mean sanitary....whatever. Mark Angulo can vouch for that!!!
