As I am obviously biased, I plan on just reading the post of contributing members. However, I would like to add a few points:
1. Kiteboarding is a fast moving sport. There is a lot going on many times, but we are not out-of-control- though it may appear so. Think about it, if it has the power to yield 20ft airs, not being in control could be lethal.
2. Kiteboarders have the incentive to ride safe as it is their body attached to the rig. Bottom line, accidents have occured. I am shooting from the hip, but I bet 99% have affected the rider only.
3. Concerning the use of markers. Regardless of kiteboarders in or around Atlantis, it is my opinion that all divers should use markers and safety sausages. Never trust your safety to someone else. As I am sure you all dive in Cozumel, I am sure you can relate to the boat traffic (which ironically occurs in blue water) which places divers at a much greater risk than kiters. I never saw our dive master surface without a sausage. I have a feeling divers accept this risk because it is a necessary evil (interestingly every boat I remember used a prop- second thread anyone?). Assuming that everything will be o.k. when you surface is contributory negligence on behalf of the diver- in my opinion. By using markers it reduces the odds of the "worst case scenario."
4. Kites travel perpendicular to the direction of wind and a little upwind. Assuming we can just ride in the blue water, assumes the wind direction never oscillates- but is directly offshore. Additionally it assumes we can just go up-wind like we have an outboard motor. Up-wind travel is difficult and one of the first learned skills that not every rider has. Furthermore, although they are tradewinds, minor fluctuations impact our direction of travel and may have us going diagonal to shore instead of parallel. Additionally, it is better kiting near shore as the water is flatter. Ever ride down a dirt road after a rainstorm? You know what it feels like to kite in the blue water. How about going to that perfect dive destination only to be allowed to snorkel? Also, sometimes kite lines and bars become twisted or fouled- not a safety concern, but you have to swim in. Rule 1 of kiting is to never go further out than you can swim. How many of you would be able to swim 1/4 to 1/2 mile with gear and no fins after exhaustion?
In summation, and I really do thank you for your opinions, safety is everyones responsibility- not just the guy in the Ferrarri. However, I will definitely have a new perspective kiting Atlantis than I did last year. I would also encourage anyone travelling to stop by and talk to the local kiters. They are a great group and many of them are dive masters/instructors. Maybe you'll be encouraged to take a lesson! See you on the water- from a long way off!
