I'm in a group going on the Grand Sea Explorer in the Red Sea in OCtober; it is part of the Explorer Ventures fleet (a franchise boat, not owned by EV). We have had to sign a liability waiver that includes initialing a statement that says:
4. I understand that EV complies with the recommendations of the Recreational Scuba Diver Training Council (RSTC) regarding physical and mental fitness for diving. I affirm that I have reviewed the RSTC Medical Statement and the guidelines, standards and recommendations contained therein
(http://www.explorerventures.com/pdf/medical_statement.pdf) and that either (1) I have no medical history or condition and am taking no medication contraindicated for diving, or (2) I will be in possession of a doctor’s statement less than one year old affirming my fitness to dive despite one or more contraindicated medical conditions or medications that I am taking.
I understand that, if I have a contraindicated medical history or condition or take contraindicated medication, and can not provide a current doctor’s recommendation of my fitness to dive, I will be unable to participate in diving activities from EV’s vessel, and that no refund or other consideration will be given.
It was recommended that we carry a signed medical with us, just in case. The embedded link is to the newest version of the form.
