Come on the boat
The full-day trip is explicitly open to non-divers. About eight hours on the water with lunch aboard, not a morning hop. You get the stops, the coastline and the lunch; you just do not put a tank on. With a maximum of six guests there is room to actually sit down. Whether someone can be dropped mid-trip depends on the day — ask before you book a full day for a person who does not want eight hours afloat.
