Launch notes
The flat water bay offers ideal launch conditions with consistent trade winds from the E-SE. Sandy beach access provides easy launching, though shallow waters require careful edge control when starting.
Gear & clothing
Gear · A 17m kite works well for the consistent 14.5kt average winds, though pack a 13m for stronger days and a 19m for lighter conditions. A twin-tip or directional board suits the flat water perfectly.
Clothing · Light rash guards or thin wetsuits are sufficient year-round given the tropical Caribbean climate. Consider UV protection over thermal insulation.
Crowd & etiquette
Respect the heavy anchor field by staying clear of moored boats and maintaining awareness of other water users. Keep sessions shorter during peak tourism hours and yield to local fishermen.
Additional notes
Check tide times before sessions as shallow areas become more challenging at low tide. The spot's popularity means early morning sessions offer the best wind and fewer crowds.
