Hydrate before boarding
Bring water and drink well before the briefing — dehydration magnifies seasickness and fatigue during surface swims.
Wear reef‑safe sunscreen
Apply mineral-based sunscreen before getting wet to protect coral and marine life.
Bring motion‑sickness medication if prone
If you’re sensitive to boat motion, take a preventative dose before departure; the ride can be choppy at times.
Communicate medical history
Complete the health questionnaire honestly — conditions like asthma or recent surgeries can disqualify you for safety reasons.
Swimwear and quick‑dry towel
Comfortable swimwear and a towel make surface intervals and reboarding easier.
Reef‑safe sunscreen
Protects skin and marine ecosystems from harmful chemicals.
Light windbreaker or fleece
Useful for early morning or cooler breezes while transiting by boat.
Sea‑sickness tablets or wrist bands
Helps prevent nausea on choppy crossings to the Catalinas.
