In addition to the extensive coverage by Tord, - I think that kite will be
quite ineffective when wet, - and there is a good chance of this in a kayak.
If you are looking for some thrill, then may be a kite will make a paddling
day less boring.

But if you are looking for effective, hands-free and relatively trouble-free
way of augmenting your paddling power, - then V-sails or small batwing sails
are the way to go.  There are at least 3 commercial V-sails,- Spirit,
Quiver, and Pacific Action. Spirit and PA have been reviewed at the
Watertribe website:

There is at least one commercial design of high-aspect, scary-looking
battened sails in NZ (with the mast all the way down to the hull bottom):
http://www.vision.net.au/~jennings/sail/sail.html , and hinged designs of
low-aspect batwing sails in NSW (Australia) by Norm Sanders and others - not
commercial, but quite popular there:
http://www.nswseakayaker.asn.au/mag/36/osdgl.html .

The last one looks quite appealing, with a low center of effort, easily
raised, lowered and trimmed.  This particular one looks a little bit small -
I've calculated 0.6 sq.m (7 sq.ft) from the diagram. With a "normal" kayak
of 23"-25" beam anything over 1 sq.m (11 sq.ft) will be too much, anyway.
The most expensive and the only permamently attached part would be universal
tiller joint (about $30), with a total cost around $70.  On some photos at
NSW website I see that this joint remains on the deck with a short "female"
lower section of the mast, while "male" section with sail is bungeyed to the
deck when not needed.
