If you are having problems and could not relaunch in what was obviously 5-6 knots (in which the kite would have 2-4 times the lift than 2-4 knots), what are we meant to make of your 2-4 knots claim? I mean seriously, you are not doing your brand any good with these over the top claims. I am sure the infinity is good in the right conditions (which I would say is freestyle in the top end of a force 3 and lower end force 4). Going head to head with these larger high aspect ratio kites in real light winds like the Core 19m and the 18m Switchblade is just making you look silly.
With all due respect Mr.UKSurf but I never said I could relaunch the INFINITY v3 in less then 4 knots or even less then 7 knots. If the kite goes down in less then 5 knots you are done. The only time I was able to relaunch the INFINITY V3 from the water in less then 5 knots was when I was knee deep of water and the INFINITY V3 was seating trailing edge first, perfect for a "hot launch". The INFINITY v3 or v2 can relaunch easy with its LE down in deep water but it needs to be blowing between 7 to 10 knots at least.
Also you heard all these Cabrinha guys on the beach, they were the ones claiming less then 5 knots not me.
Plus you saw how stable the INFINITY V3 was in the air. Again if you are looking for a high performance kite for racing then the RACER 17 will be the one not the INFINITY V3.
So do me a favor and get a chance to demo the INFINITY V3 or the RACER 17 or even the CABRINHA 18 and the CORE 19 kites so you get a better understanding. But try them in 7 to 10 knots because bellow that it's not fun and you will need a Racer or a big SUP board if you try them in less then 6 knots, but at least get in the water and do something fun.
Any way let me know how else I can help you.
