On the dive deck
Set up your gear in your assigned spot and don't sprawl into others' areas. Rinse cameras and computers in the dedicated camera tank — never the regulator tank. Hang wetsuits to dry, don't leave them on benches. If you borrow a tool, return it immediately.
Punctuality matters
Briefings and skiff departures run on tight schedules. Being five minutes late delays 15 other divers. Be geared up and ready before the briefing ends.
Respect the crew
Crews work 14-hour days with no shore leave. A genuine thank-you, learning their names, and tipping at the end (5–15% of trip cost is standard) goes further than most divers realize.
Photography and personal space
Always ask before photographing other guests. Don't crowd a marine life subject another diver is shooting — wait your turn. On the boat, common areas are fine for photos; cabins and bathroom areas are not.
Sound and quiet hours
Salons echo at night. Most boats have an unwritten 22:00 quiet rule — keep voices and music low after that. Use headphones. If you're an early riser, prepare your gear quietly.
