I have acouple of Searns inflatables but I don't use them anymore because the wind and wave effects them badly. My advice would be rent kayaks from any number of businesses. I do know that the business behind the Holiday Hotel has Hobie kayaks as well as Caribe Island Resort...to the south of town. Kayaking to the reef is doable...although past the reef would be abit ruff. Besides, most everything to see IS inside the reef. Good luck!! Also check around for kayak rentals for the lagoon behind San Pedro. I live back there, and the scenery and birdlife is great.

Gone fishing!!
