If that thing pops out of water, it will be a missile on a leash.
not just that the spreader bar/ harness/kitelines are made to take that much stress. When we did a few pull ups many many moons ago.. we straighten a hook on a spreader bar in a day.. what is stopping the lofting and then falling 50+ feet?
people slam the guys that do the high jumps snowkiting ( the kite gliding down the side of the mountain ) for the same reasons
just a bad idea all the way around.
Stan if you want to fly buy a paraglider or a powered paraglider. it is made to fly
