Hello Mark, You'll need a lot more than just a board and kite, think of a wetsuite, a trapeze, safetyaccessoire such as lifejacket (small one). At the beginning a 2mtr directional board would suite you. Kite depends on windconditions, take at least 7mtr2 for 3Bft. No, you should take a beginnerscourse with one of the kitesurfschools... Cheap rig? Peter Lynn Basic board and Waterfoil 5,7 (allthough Kitesurfers Aqua 6 or 9 will do a slightly better job
www.ks4u.com / A-qua ) If you can read the Dutch language, try vlieger.pagina.nl , 'course there are a lot of links on kitesurfing... Also look on the maps of the waterways.. you'll need shallow water, max hipdeep...
Wanna know more? Write me in personal... greetzzz ans succes... Martin
