Frequently asked questions

Do I need to be certified to join this trip?

Yes—this is a certified divers-only two-tank boat dive; you must present proof of a valid scuba certification at check-in.

How long is the trip and how many dives?

The experience is typically around five hours and includes two guided dives: a wreck and a reef dive, with surface intervals aboard the boat.

Can I fly the same day as diving?

No—Hawaii operators advise a minimum 18-hour surface interval before flying to reduce the risk of decompression sickness.

Arrive at least 15 minutes early; bookings may be canceled without refund for arrivals more than 15 minutes late, per operator policy.
