Foilai vs pūsles

Reikia prisipažinti kad vaizdelis kai plaukia su kaitu man gražesnis nei su burlente. O kur vaizdelis ten įsivaizduojamas rojus. Tad karts nuo karto vis užkliūna koks straipsnis. Šis man atrodo puikus foilų ir pūslelinių kaitų palyginimas.

Tikiuosi nepyksite kad neverčiau ;-)


Claim #1- "Foil kites are more powerful and efficient and fly better in lighter winds than inflatable kites."
Status = Partially true. If it is tuned correctly and flown skillfully, a foil kite will fly and stay aloft in wind slightly lighter than what it takes to keep a bladder-inflated kite in the air. And because it weighs less, it will rise faster and give more power on the "upstroke" when you are getting going. Once you're up to speed, the 3d airfoil shape of a foil kite pulls more for its size and goes upwind at a better angle than an inflatable kite. But foil kites have a tendency to "overfly" the wind window, "front-stall", and collapse, especially if the wind is gusty or shifting in direction, whereas bladder-inflated kites hold their shape much better and respond to wind changes better.

Claim #2- "Foil kites are more convenient and less of a hassle than inflatable kites."
Status = Partially true. It is definitely nice not having to pump up your kite and worry about bladders and valves leaking. Also, the foil kites pack up nice and small and you don't have to lug a pump around. However, it takes a longer for a foil kite to recover from a crash, because it gets really heavy with wetness and sand and there are complex bridles that take a long time to get untangled. Further, foil kites require "tuning" to keep them performing properly after their lines stretch with use. You need a PhD in aerodynamics and fluency in German to figure out how to tune them in a way that will make them fly better and not worse.

Claim #3- "Modern, closed-cell foil kites relaunch from the water as well, if not better, than inflatable kites."
Status = Total bullshit. IF you are standing in shallow water, and IF there is lots of good wind, and IF your foil kite just happened to crash in the perfect, untangled position at the center of the wind window, then it will relaunch about as easily as an inflatable kite... except that it will yank you downwind with crazy force because you're relaunching it in the "hot zone" instead of at the edge of the wind window. Of course, if your foil kite crashes anywhere other than at the center of the wind window, if it does any folds or inversions when it's falling out of the sky (which it will), if you're in water where you can't touch, if the wind is less than a steady 12 knots, if your feet are in a floaty directional board that doesn't provide much resistance against the kite, if the kite happens to get a little water in it when it crashes, or if a wave washes over the kite, it will be next to impossible to relaunch. I have only been able to do a deep water relaunch 1 out of the 5 times I have accidentally crashed my Flysurfer Speed 2 in deep water. And I ain't no kite kook, neither.

Claim #4- " Foil kites let you jump high and get major airtime in relatively light winds."
Status- True. I am not a very good jumper, but I have had some really nice, floaty airs while riding my foil kite. The only thing is that jumping makes you susceptible to getting in a position relative to the kite and the wind wherein the kite will collapse on itself and crash out of the sky. The difficulty and hassle of relaunching a crashed foil kite tends to make one more conservative about jumping.

Claim #5- "Foil kites turn fast."
Status- Not mine. My 12 meter Flysurfer Speed 2 foil kite turns at about the same speed as my 14 meter inflatable kite, if not slightly slower. When I have to turn the kite for jumps and transitions I need to plan ahead and get the timing right so I don't sink while waiting for the kite to turn. At least the bar pressure required to turn the kite is relatively light.

Claim #6- "Foil kites are safe and easy, especially for self-launching and landing"
Status- Mostly false. It's easy to self-launch a foil kite in most winds, and it's easy to self-land a foil kite in light wind, but it's extremely sketchy to self-land a foil kite in strong wind. Also, because of their powerful, lofty pull, their propensity to fold, tangle, and re-power in gusts and wind shifts, mediocre de-power systems, and their sometimes sluggish steering responses, they probably increase you're likelihood of having a serious accident. I chose not to fly my inflatable kite in wind over 20 mph, and I'll definitely excercise the same caution with my foil kite.

Conclusion- Foil kites may be better now than when they were first invented, and maybe even a little better than my 2-year old Flysurfer Speed 2, but they still have a long way to go before they are as safe, convenient, and dependable as inflatable kites for use on the water by average kiters. I would say that at this point in time, foil kites are most appropriate for good, technically-minded kiters who rarely crash the kite and who sail "door" style twintips close to shore in flat, shallow water and steady, light to moderate winds.
