I can vow for that! Costa Rica has incredible surfing (look further than tourist traps Jaco and Tamarindo, so many much nicer places around), the VERY BEST wakeboarding (well OK that's a bit exagerated, but really, it's nice!
at Lake Arenal. Kiting is really good too, but the season ends in April somewhere, usually. For kiting go to Bahia Salinas or Lake Arenal. No cables in Latin America yet, though they're setting a Sesitec up in Panama now if I'm correct.
Contact me if you want more info about Costa Rica, I'd be glad to help out.
