Gear & clothing

Gear · Bring 17-19m kites to maximize light wind potential on low-wind days. Use directional boards or small wave boards suited for flat-water progression and light winds.

Clothing · Wear a 3/2mm wetsuit during spring (March); water temps range 50-60°F. Consider a light rash guard for protection from sun exposure during longer sessions.

Crowd & etiquette
