I would think so, but dont know...
I've ridden the 18m North Dyno 2011 with 5 lines quite a bit on my raceboard in marginal winds, and I don't think the 5th line helped much in trailing edge down relaunches. If it was light enough for that kite to backstall and wind up trailing edge down, there was pretty much no chance of relaunching. Also, I didn't think pulling on the fifth line really made much of a difference compared to pulling the two front lines when trailing edge down.
With leading edge down though, the fifth line definitely helped with relaunch. The race kites being high aspect ratio and flat don't roll up on their wingtip in light wind, so the fifth line really helped. Not sure the fifth line would make much of a difference for the freeride style lightwind kites that have a more swept back wingtip and curved leading edge to make it roll up on a wingtip by just pulling a rear line.
Sorry if I was not clear, to both you and Laughingman
The only reason for having the 5th line should be in order to tilt it on its back, and then get it turned around TE down, as this is the only way you can get a kite up in really low wind IMO.
Amd WHEN it is on its TE, you pull the frontline(s) and a 5th would hardly make much difference here (but maybe just a little) - it is mostly in order to get it on its back when you are drifting in the water in marginal winds, where the LE tends to suck down to the water, and/or be filled with water.
Backwards relaunch is also an option, but launching TE down (which requires some struts so it stays up better) will always be more efficient because of the profile, so can be done in less wind.
Furthermore - the video shown earlier was in FLAT water, which most often is not the case around here and in many open sea spots.
LE down the waves/chop will splash water inside the LE, so it will be much heavier and very often impossible to relaunch backwards because of this.
Not sure about the Cloud video Ronnie - is it supposed to show how good the Cloud relaunches, or how difficult it is ???
Is he riding and going upwind on a TT ? Maybe mistaken, but even if it is a door, it requires a lot more wind than a hydrofoil.
Sorry, I am not convinced that these kites can relaunch in very marginal hydrofoil wind
But agree, the light ones are WAY better indeed
knot_moving, you are right, in 10 knots I often ride a 9m2 kite, so a 17 powerful kite would be WAAAAY too big.
Sorry, it could just be me - but all videos showing relaunch in almost no wind, seems (to me) to have no reality for most riders, when talking hydrofoils
Just like the Epic low end claims
