Loftywinds said.. unless the wind is light, doing what nobo said above by walking the lines is very risky and you have almost no control
of the kite should it suddenly catch wind and rip the lines out of your hands.
Most of us are taught the other way for a reason.... because it's safe(r) dugh!

In 8 years of kiting I have yet to see a single newbie who isn't going through a great deal of struggle attempting to wrap their lines when the wind is blowing around 25 knots. That's right! A lot will simply fail (especially in deep water) and give up (releasing the whole kite), drifting up to a few KM downwind getting other people worried.... and many will
forget to lock in the leash line, which results in the kite powering up while the lines are wrapped around the bar! And how about when two kites tangles and people start wrapping their lines...you get the picture. This is not speculation, but rather the conclusions I draw from many years of daily observations at my local spot.
Over the years we've only had thousands of students self-retrieving their kites without wrapping lines and without any assistance from the instructor in strong winds (we get winds up to 25 knots almost every day in season) without a single incident or injury. Prior to this we were teaching the ''official method'' and trying to get all students to wrap lines by themselves, in strong winds and deep water. The level of difficulty was too high, the success rate pretty low and too much time was spent assisting and rescuing the students. As a school who operates in 100% deep waters and 90% strong winds, this left us with 3 options:
1-Stick to simply demonstrating self-rescue with wrapping lines with hands-on assistance from the instructor and avoid the trouble of getting the student to practice it alone in actual deep waters or without touching the ground (what the
majority of schools do!), or simply don't teach it at all (what some schools do!). All this hoping the student doesn't get in trouble and has to self-rescue alone during the lessons, which typically results in a student rescue.
2-Have all students successfully attempt at least one deep water self-rescue by wrapping their lines without the instructors assistance, which demands: a lot of time (at least 1 hour) and an instructor in the rescue boat ready to help. Yes, this takes an hour to teach this correctly for most students in strong winds if everything goes reasonably well and quite frankly is when a lot of students think of just giving up the sport. It's just too difficult and stressful for the average student, which is exactly why most schools opt for option 1 and also why most newbies aren't actually competent with self-rescue!
3-Come up with an easier, quicker and more efficient method that is safe and doesn't involve wrapping lines and is most importantly easily achievable by any students, even in strong wind conditions.
By choosing option 3 and working on improving our teaching methods we managed to have zero student boat rescues in the last 3 years and more importantly building confidence in every student's ability to genuinely get themselves out of trouble without any help.
So yeah keep on wrapping in strong winds, I obviously have no idea what I'm talking about.
