Open Water Scuba Certification

Participants in the Open Water Scuba Certification cannot fly in an airplane within 24 hours of their dive.

The main concern with scuba diving and flying is decompression sickness (DCS). Your body needs adequate time during an ascent to off-gas excess nitrogen, or you can form bubbles in your bloodstream, possibly leading to DCS.

If you have any doubts about becoming seasick on the water, we recommend taking a Dramamine® Motion Sickness Relief tablet the night before your trip. Some people recommend taking it the night before your cruise and then again that morning so you will not feel so drowsy.

The minimum age to participate is 15. This activity requires at least one adult to accompany children..

If a date or time is not listed on the calendar, it’s sold out or unavailable for another reason. Support cannot assist further if a date or time is not on the calendar.

If you find a date and time that works for you, book it NOW because things always sell out at this time of year.
