Would be better if you are Nitrox certified as well. Dody there are concerns one should have with going on a liveabord during a pandemic.
So you think Quarantine in the Maldives is nice? Think again!
Also there are other ways to do an emergency ascent in an OOA situation that is not CESA. It was taught to me by my instructor who was also in charge of commercial diving on oil rigs. It's it something to understand and not taught. Then again I don't see many instructors teaching students how to deal with vomiting underwater which can happen.
Some of the people on this forum will know what I am talking about when it comes to using another option to survive an extreme emergency for OOA with no buddy nearby to assist or so you can get to that buddy. I keep my BCD bladder clean and would rather risk a lung infection which can be cured than drowning when I could self rescue.
