Thanks for your post, Wouter. Rob has said most of it. OutLeader kites are different--they're nothing like kitesurfing kites--nor like foils, nor like Peter Lynn kites, etc, etc.
KiteShip has been designing, building and sailing kitesailing kites for 26 years. We've done the flexifoil thing, we've done the kitesurf kite thing. We've been to Weymouth half a dozen times; we've done 30+ under kites. We're kite buggiers, kitesurfers, kite sailors, kite designers. Yes thanks, we understand the SEVERE limitations and the dangers of putting large, powerful kites onto small sailboats.
This is why we invented the OutLeader. Kites aren't new--they've been used for centuries to pull sail boats. OutLeader spinnaker replacement kites are new. They AREN'T designed to replace your rig. They AREN'T designed to sail upwind--any more than any other spinnaker is designed to sail upwind.
What they are designed to do is to kick spinnakers' butts. On all boats, at all sizes. They aren't meant to compete against kitesurf kites on kitesurf boards. These devices are great--well designed and well built. If you wanna fly, put one on your catamaran. Lotsa guys are trying to do this--not us.
OutLeaders are designed for the Rest of Us. Those of us who like to sit down, right on the boat (or trapeze!). In this use, they've been built--and successfully sailed, and raced, in sizes an order of magnitude larger than any other kite--ever.
If you're looking for a kick-butt spinnaker; check them out. If you're looking to blame kitesurf kites for damages, injury and destruction; talk to those other guys. They ain't us. ;-)
