Wear closed water shoes

Time for tides
Meeting times move with tide and weather—arrive early and confirm timing the day before to avoid missed transfers.
Sun protection matters
Even in spring, reflected sun on water increases UV exposure—use a reef‑safe sunscreen and a brimmed hat before/after the activity.
