Hi Brett, I am Involved in the Surf Shop in Grenada, I own it. We sell Ocean Rodeo, Caution, and Liquid Force. I just became an IKO instructor, and have worked out an arrangement with Ruth and Andrew at the Scuba shop at the Rex to use their dingy for some training off shore.
I used to Teach diving at The Rex 4 years ago before opening the surf shop. The reason you haven't found anything about kiteboarding is that I STILL haven't gotten off my ass and gotten a website together... too much playing.
The wind at the Rex is usually cross off shore, and fluky and gusty due to the hotel, and hills near the beach, but it cleans up a bit off shore, and launching from a boat 500m off shore should be a possibility.
As for kite sizes. I'd say pretty much all you can afford. In summer the winds are 5-15 knots, and in winter, 12-25, but it is really all over the place all year. So what's that? 9-16, and 20m? I've got kites in stock at great prices if you are so inclined
It will be great to have another person to sail with!! anything else I can help with, please e-mail me at
