Another point to consider when it comes to booking boat charters -- almost all the boats have a minimum number of paying customers require in order to go out. For some it's as high as 6-8, others as low as 2-3. If you wait until the last minute to book your charter, you may find they've already rescheduled the next day's charter due to insufficient bookings.
Good Point!! It's not easy running a dive op in Hawaii. I have many friends who own boats and the overhead is unbelievable! Advance booking is just a smart way to plan your trip. Diving is really cool and you wouldn't want to miss it if you were only going to be here for a short visit.
