Ive been using the avanti machine 10.0 and 7.7 for formula and slalom racing in the SF Bay, the gorge and baja for the past 2 years and imho they are the best thing out there. The weight savings is huge with the membrane technology. The 10.0 feels like a 7.0 and the 7.7 feels like a 5.0. They've lasted way longer than normal monofilm sails and pull like a truck. The best part for me has been the transitions- its so light in the hands!
I really cant say enough about the sails.
Expensive but worth every penny

Think I was probaly the first in US to try one... Bought 1 set each year, 2012- 8.5m2 M1,2013-10m2 M1X, and just got today 6.9m2 (M2) ; all race sails... Hard to go back to regular sails after Avanti, so much lighter,
membrane after 3 years dosn't show much wear, and they just feel different, more natural. I do think they worth the extra $

Here's another way to look at the whole weight issue. My assumptions are that rig weight is more important that raw sail weight and that sail performance is optimized on the correct mast, so I've taken some manufacturer's "light" sails and paired them w/ the same brand's lightest mast and compared. Some interesting observations.
-The Hot Sails KS3 (3-battens) is heavier than their Firelight Pro (4-battens)
-The Maui Sails Mutant (4-battens) is heavier than their Ghost XT (5-battens)
-these heavier sail weights above are offset by lighter, shorter masts
-mast weight may be just as important as sail weight
I only did the comparison for wave and freestyle sails and some brands were omitted because their websites did not have sail weight data or I just forgot about them. Rig weight is just sail plus mast. I assumed booms and extensions were interchangeable.
Of course this is just raw weight. How light a sail feels, how durable it is (or isn't), do you actually enjoy using the sail, and whether or not the sail is available or affordable are factors that are just as important as raw weight.
Sorry in advance for any mistakes I may have made on the chart

Nice job Kevin, but this is really splitting hairs IMO, does 3 or 4 ounces really make a difference? Seems like it would be really hard to tell at that point.

But if you compare the top 4 in each column and throw out the heavier rigs the difference is just a few ounces.
Wouldn't it make a bigger difference to use the lightest and smallest possible boom for each sail? Harness lines? They've got to weigh a considerable amount when full of water and sand

For the weight weenies I wonder what the difference is between regular fixed harness lines filled with sand and water and those plastic clip harness lines that wear out your boom grip prematurely

I could buy the lightest and most expensive stuff but my concern is that someone on heavier cheaper gear could make me look foolish. I would have wasted my money. The Walk of Shame.
