It is extremely important to know a few things going out on the water. The rules of navigation at sea. How to Self Rescue. The right winds / location.
Odds are you will need a 2 kite quiver. It sounds like you get some real strong winds. I would suggest something in the 7-9 m range depending on the
kite.
You can use an LEI on land so don't rule out inflatables. Usually you are extremely hard on your 1st water kite. It would be advisable to get a used
one .
Flysurfer, H.Q. SkyCountry and Peter Lynn all make Closed cell kites that can be used on land + water that stand up to a beating pretty well. Still a
used one is a good idea.
Folks are right about the lesson thing. Lessons will propell you in to the " self sufficient " stage. Trying to self teach can be a long hard road
that has made more than one person quit before actually getting started. It will be the BEST money you have spent.
