Grief about unhooked launch is probably caused by tens of thousands of successful hooked-in launches every year by everyone and ability to see following issues with unhooked launch by experienced riders. Such as:
- launching in strong/gusty conditions takes a lot of control and attention, and few riders have exercised their single arm enough to compensate for 70-80 kg of their body weight while hooked-in. Being yanked by kite for 5-10 feet in overpowered but controlled manner is way safer than losing kite to a gust which you can't simply hold.
- unhooked launch gives rider false sense of safety and is not a replacement for pre-launch checks and launch safety otherwise (and some will consider it as such)
- unhooked launch is a thing of dual-line kites past when kites were lacking depower and were overly dangerous to riders to start with
- hundreds of less experienced riders can't be trusted to launch with one hand on a bar and they'd freak out and send kite flying away so much more often that it would be a major danger for others on the beach
- not only you'd endanger people around you by unnecessarily letting kite go (way more often than needed) but you will damage your kite a lot as well by crashing it on sticks, brush, sharp rocks and shells. Twintips are usually parked fins up and beautiful sharp hydrofoil blades are waiting for your released kite to land on them. Bring them babies on
- there's no safe carabiner (to replace quite silly chicken loop system) and rope spreader bars are incompatible with unhooked launch. You don't want to teach two separate systems, it's plain wrong.
- how do you reverse launch (flying kite backwards up first) in light wind unhooked? Using two different launch techniques is not safer.
- remember, in deathloop, a QR is not always a solution and with one hand not being able to hold the chicken loop you would end up being dragged by the leash while deathlooping with no chance to recover until you detach the leash. You need a third hand on the leash then by unhooked launch logic
- many riders attach leash to the back of the harness and it's not a pleasure of watching someone being dragged backwards
- Pilot's predictability is important for all. Everyone wants riders to succeed and everybody knows QRs are very rare, especially at launch (and if otherwise - guys should go back to training). A proper assistant will not launch you without looking if lines are not caught up, or pilot hooked/holding bar in reverse. There's a lot of safety in prevention and focusing on last resort is not right.
If you see a person launching unhooked, my advice - stay away or help them learn proper launch techniques and safety so they don't get your beach closed. While some experienced riders are ok doing questionable/risky thing - it doesn't mean it's advisable to follow the example
"You can" doesn't mean "you should"
Let's just give all airline pilots "Eject" levers so they can save their
lives and let others
deal with machine crashing. Nobody wants to deal with your kite falling out of skies uncontrollably - people shouldn't pay price for "your" decision to go kiting. Many launch spots are crowded and safety of pilot is less important than safety of others.
And when unhooked launch becomes pilot's vs mine
safety choice - yes, I will give grief and will help you to be safer to others and yourself
