The setup I am considering is this:
Kites: 12m mastair, 9m speedair (Moded to quad-line with additional fifth line FDS) (I was told these kites would work best as they are more traction based than newer kites and don't have the lift. (Which ofcourse I dont want.)
Kayaks: Necky Nootka Outfitter(22-ft, about 430lbs (USA) with both passengers), Seaward Passat(22-ft) (about 410lbs with both passengers)
When to fly: Calm days when the waves are not up. 5-15mph winds. (afernoon trips for now)
Set-up:
Both boats are very seaworthy. But if going off of down wind, I could add outriggers for a trimaran setup or connect the boats together (maybe 10 ft apart) to make a catamaran. (Could a keel be as simple as cutting two boards into fin shapes and connecting the tops of the boards with a perpendicular third board and fitting this over the center of the boat?).
As far as being able to let the kite drift down wind while letting out the lines: Do you think I am able? This would work well in mild conditions right?
I could also just launch from the shore then launch the boat with the kite in the air right?
I think I would have to modify my boats more for sailing. I would definitely have to add outriggers and a keel then. Also, I would have to cut a mast hole in the middle of my Kevlar boat (Need to buy special equipement for that). I would think that the tipping forces in sailing would be greater that kiting, all of the power from the kite goes to a point relatively low to the kayak, wheras mast and sail is like a giant lever.
I am considering either harnessing the kite to me or the boat deck. If I get into trouble I can just activate the FDS or a quick release system.
Thanks for your comments.
