This season in hydrofoil land... things have got insane!!! We riding more powered up than you would have even dare to consider 12 months ago. We pushing our 15m R1 in upto 18knots, 11m to 24knots and well over 30knost for 8m. The new foils even when full depowered dont fall back into the wind window as much, yet still crank upwind even when full depowered. I had the 11m out today in 18-22 knots, just about full depowered at times and still hammering upwind. This is making launching and landing a bit nerve wrecking. do not hot launch.... and keep conmtrol of the kite. Sheet them in enough still they stall and start edging back and they seem to lose just about all their power. But let the rear lines go, and as soon as airflow restarts over the wing its game on... you going to get launched. Best bet is 45 degree launch in high wind, keep control at all times of the kites forward movcment by grabing the steering lines and holding tension on them. As for speed, let the kite breathe, dont over sheet and dont be scared to depower abit to get the kiet flying clean as possible. We now flying the kites super low to get maxium pull upwind , ride the gusts out, each gust is extra upwind surge. low kite also stops you keeting lift off foil and out of seat, use all that pull to get upwind. Strangley enough we stealing tips from the buggies... we going super short on our lines 18-20m for small kites and 21-25m for the larger sizes. If very very powered, start with kite high... find your upwing angle lock it in then bring the kite down.... you'll hold your line. and let the kite breathe. Even more so if flying the kite in the bottom of its wind range... over sheeting causes the airflow over the wing to stall and the power "turns off". Heading back down wind... doesnt matter how over powered you were up wind, once you gte to to the top mark, let all the depower out... maxium power, bring kite up high and send it down as you round the mark to launch you down wind. on the smaller sizes you could even back loop but its risky as the pull is instnat and EPIC... on water if it goes wrong you luanched down wind around 75m bouncing along the water... on land thats gonna hurt, alot! so maybe best just stick to up high then striaght down and you round and point down wind. Sign the kite 2 more times and let it breathe again with abit of bar pressure again nice and low. Slowing, full depower.... bring you kite up high, and depending how powered up tease the kite beyond 12 overhead to act as a slight air break as you turn back upwind slightly. Best tip for upwind line. gte some forward speed then lock in you line upwind with kite overhead , and then bring the kite down low... let kite breathe and work its way to the edge of the wind window and then dont be afraid to let more depower out to power the kite up even further. Let it all out and feel the pull build and build The power you can hold down in the situation is vastly more than if you reaching and then tried to carve up wind, if you try full power and then carve up wind you end up getting dragged off line and natural tendency is you bring kite up higher to spill off the power.
