It ain't a "cheap" kite, but a good one, especially for the ocean and when you are learning a 7m is cool....and dad will want to use it when it's really windy

If you have surfed before, then you will only need a 7m for a long time as you can get a sufboard and a twin tip. Once you get to 65 kgs. you may desire a 9m or a 12m. Get Dad in to it, and the world is your oyster.
Just be sure to have lessons from someone up there about safety proceedures and learn the rules (Darren Marshall can do this well)....because at beaches, you must yield to everyone....these kites can be leathal weapons....good luck.
