www.seabreeze.com.au/forums/Kitesurfing/Foiling/Flysurfer-Peak5-#2755919Before the seabreeze completely finished for winter it had one last puff today, enough to try my new 4m Peak5. After a few trips to the beach where the wind did not blow as forecast, today it was gusting up to 11 knots on the beach with my wind meter, good enough for the 4m

I've previously used the 4m Peak4 and it was a fantastic kite, it was perfect for 10 to 16 knot seabreezes which are common in summer. So I wanted to see how the Peak5 version performed. Hotlaunching the kite on the beach it felt like there was plenty of power to get my 65kg up on my 990 sq cm foil. When I got to deep enough water a couple of figure eights across the window and I was up on the foil.
There were no other kiters about but there were two wingdingers on 4m and 5m wings from Sydney further out on the bay who were only intermittently foiling. I was able to easily foil upwind and ride some small wind chop downwind riding left and right as the chop appeared and subsided. The kite was as easy to fly as the previous model and only a few small differences. It felt a bit tighter and more responsive and there was virtually no flapping when fully depowered foiling on wave power. It pointed a little higher upwind and drifted possibly slightly better than the Peak4.
The wind did pick up a little and the wingdingers were able to get themselves foiling most of the time. Spent a little time foiling with them. I felt a bit sorry for them as it was harder work for them to stay foiling and I was able to easily outpace them and point higher.
Very happy with these new Peak5 kites. Virtually all kites nowadays are only incremental improvements on what has preceded them apart from material advances like Aluula. The Peak5 kites are made from a tougher fabric than the Peak4 kites and they are slightly lighter and definitely have improved on what was already a fantastic kite for foiling. Still the Peak4 kites I've sold which are over 2 years old are still going strong and in excellent condition. A kite designed for snowkiting up a mountain isn't going to be stressed pulling someone on a hydrofoil
