any views on 13m vs 15m size Capa...
im looking to go out in super light conditions (6-15knot) and also have enough power on both a twin tip as well as foil board so figure 15m May be best (I'm 80kg). Also hate that feeling of being underpowered! I note the Flysurfer soul goes up to a whopping 21m so relative to that 15m doesn't look excessively big. however some people said Youre generally overpowered on 15m (particularly on a foil board) and recommend the 13m?
I've never even seen a Capa, so this is going to be a relatively uninformed post from that perspective...
However, I'm the same weight as you, and I live for the days where I can foil before the wind kicks in, and then switch to the twintip if the wind comes up. I also live in Brisbane, so the wind 'coming up' means most likely under 15 knots - so I would say 60%+ of my riding is well under 15 knots. I just thought that matched up well enough to your target of 6-15knots split between Hydrofoil and Twintip that my input might be relevant.
I currently fly Flysurfer Sonic FRs (2015-2016), so a bit different to the Soul and the Capa (slightly higher AR), but I would guess close enough in performance that it's relevant.
For two reasons - I would go with the 15m.
- If your low end target is really 6 knots - I would want the bigger kite. If your target was ~7 knots - it wouldn't matter as much, but a true 6 knots is hard, and I find the bigger kites make it much easier both to get going and to keep momentum. The bigger the kite, the more the the turning sucks (extremely slow), but if you can keep momentum in the foil, the 15m has a lot of grunt to help you keep flying through the turns. I find the 15m to be an absolute blast in the 7-11knot range.
Above 11-12knots knots is where I start to feel overpowered on the 15m and foil, but I'm on a 1000cm2 surf wing. I could hold 13-15kn on the 15m and foil, but it would be really hard work, and I would most likely be looking to change down kites, or swap to the twintip. If it was 10kn when I got to the beach, I would most likely put up the 11m if I was going to foil.
- Second reason for the 15m - Twintip in < 15knots. 11+ knots, big board, and 15m kite = Awesome fun. 13 knots+ consistent - normal twin tip and having a blast. 11kn+ and I'll be unhooking and jumping. At 15knots, I would be pretty much fully lit - enough that if I turned up at the beach and it was already 15knots, I would really be tossing up whether to take the 15m or 11m (I could handle the 15m, but I would likely be too powered for comfortable unhooked tricks).
So... That's my experience based on the type of conditions here (because we do get a lot of true 6-15 knot days). You probably will start being overpowered on the 15m and a foil pretty early on in the double digits (which the 13m would help with), but the trade off is that the 6 knot end should be easier, and in anything over 12 knots you should have ample power on the 15m and twintip.
Your conditions in WA are going to be very different to Brisbane, but after a few drinks I just felt compelled to chip in...
