Listed duration plus your own logistics
The product pages checked here list approximately seven hours for the certified Kerama boat dive, eight hours for the introductory dive-and-snorkel day, and nine hours for the full-day snorkeling outing. Those durations are the operator's estimates, not a guaranteed finish time or a door-to-door schedule.
The certified dive lists a 7:30 a.m. meeting at Miegusuku Port. The other two products meet at Marine Club Berry Naha; their final meeting time is sent the day before. Designated hotel pickup may be available, but it is not a universal Naha hotel transfer. Check your exact hotel against the operator's list and confirm the pickup request deadline.
Keep the day clear
Allow time to reach the correct port or shop, check in, change, return to your hotel and handle any delay. Do not put an airport departure or a tight reservation immediately after the listed finish. The official Okinawa safety guide advises against flying on the same day after diving; ask a qualified dive professional about the right surface interval for your schedule.
If you are prone to seasickness, ask the operator about the boat, route and suitable preparations before booking. The full-day products include time on the water, and one listing mentions motion-sickness medicine in its included details; that is not a substitute for your own medical advice.
See the port and pickup comparison and check what can change with sea conditions before arranging the rest of your day.

The official Okinawa safety guide advises against flying on the same day after diving. Ask a qualified dive professional how to plan the interval for your itinerary.
