Great question, and currently very close to my heart!
Hitting my mid 50's and surfing becoming a distant memory my wife saw a group of kitesurfers and thought it would be just up my alley. After checking it out I couldn't agree more. A new challenge for me, it looks to be a great sport.
I had the misfortune of using a "coupon" to get a discount on 5 hrs of lessons, split into 2 sessions - my first mistake.
With a group of 5 people we were all flying the kite on the beach fairly well after our first session, observing other peoples mistakes as well as my own enhanced my learning.
The second session was fairly gusty (April - Melbourne) which was good in a way to learn about reading the kite in the air.
However, no body dragging just straight into dragging a board out and back. Out was ok, but I crashed the kite on the way back, subsequently had to release the kite and board as I was nearly drowning. Instructor was not impressed with me or the other students who kept making "mistakes".
Got some basic gear and hit the beach, tried to self launch after watching utube and took the kite up through the power window - second mistake, I went flying with it. Back home I started to read as much as I could and look at the progression lessons. I realised the instructor hadn't really mentioned much or any theory at all - biggest mistake.
I have since had the kite up on the beach a couple of times but had more failures than successes and haven't been back in the water as my confidence has taken a battering (Would rather learn slow and safe at my age!)
After making a couple of inquiries I have decided to invest in private lessons, hopefully with a tuned in instructor / school.
Would I recommend the coupon, school or instructor I used? - NO WAY
If I were to do it again, I would take a 1 hour group lesson as a trial and then move into private lessons.
Based on the east side of Port Phillip bay, hopefully the hardest thing for me to accomplish over the summer will be to get a quality instructor.
I hope my 2 bits helps someone else
Cheers
