We have children who are over 10 and certified divers. Are they OK to dive on a liveaboard boat?
Yes, no problem. If they are between 10 and 12 years of age, they can go to a maximum of 12m. If they are between 12-15 they can go to maximum of 21m. That is a standard set by PADI and the Recreational Scuba Training Council (RSTC). Normally the supervising adult is required to dive with their children unless special arrangements are made in advance.
