People picture the Divemaster internship as diving every day, which is true, and as a holiday, which it is emphatically not. Here is an ordinary week from the middle of one.
Before the guests arrive
Up at half five. Tanks checked and loaded, kit laid out by name, boat fuelled, and the day's site list confirmed with whoever is leading. This is an hour and a half of work before anybody says good morning to you.
On the boat
You are the person who notices. Who is quiet, who has put their BCD on backwards, who said they were certified in 2009 and has not dived since. Guiding is fifteen per cent navigation and eighty-five per cent watching people.
The afternoons
Skill circuits, mapping projects, rescue scenarios, and the endless business of rinsing and hanging forty pieces of kit that are not yours. The dive theory exams sit in the evenings, and they are harder than the Open Water ones by a wide margin.
What changes
Around dive thirty you stop thinking about your own diving entirely. That is the actual qualification - the card only records it.
Would I recommend it
Yes, with one caveat: do it because you want to work in diving, not because you want to dive a lot. The second is much cheaper to achieve.
