Hey cp,
We are not flaming "bow' kites, I ride them myself. I have flown "C" kites for more than 6 years now and I have been riding bows for a couple of months and have only just started to speak of my experiences after a minimum satisfactory time spent flying them.
They are a great fun kite and could possibly be a step into the future of kiting, but I ain't sayin' that for sure.
As I said previously, there is nothing wrong with them so long as they are fitted with a sliding leash system so you can throw the bar and completely disable them. Again, flown in their wind range they pose a smaller risk than when flown overpowered (which is easy to do).
The relaunchability is not as high as a "C" kite although if they do fall without tangling, they are much easier to relaunch than a "C". The problem exists when they either luff and go slack line, or when they are rolled in surf and bridles tangle around the wingtips. I have seen Crossbows invert and collapse, twist and bowtie and relaunch inside out, as I have also seen on the Halo although not to the same extent.
Once these kites tangle, they stay powered upside down on the water and will drag a rider quickly along, this is why they need a leash. Cabrinha and Naish have a ring for attaching such a leash but it is too far away for the rider to grab it in the event they need it.
I agree they can give newbies a false sense of security until something goes wrong. I still wont ride mine more than 400m off shore until I gain a bit more confidence in their stability and ability to relaunch.
To user, there will be plenty of accidents come from "bow" kites, they just haven't been around long enough yet. 6 months compared to 10 years of "C" kites and most of that being prior to safety systems.
"Bow" style kites are fun and easy to ride but I still recommend that they are for intermediate riders to experts. Get at least a season of experience under your belt before you buy a "bow" kite.
Just my opinions as a school owner, instructor and IKO Examiner,
Good winds
