Re: Freediving in Mauritius
Local SCUBA Instructors don't have a interest in "Apnea Diving", the basic reaction is "why do you want to hold your breath when you can scuba", also, "free diving" no money in it, a SCUBA dive goes for 35-40 euros, they're in it for the money and "free diving" is well free, (pardon the pun). I was toying with the idea of setting up a apnea dive school affiliated to a SCUBA centre, not much interest expressed in that by the locals either. Some of the locals say that they have free dived to 30 odd meters but always decline my invitation to dive with me, do pool statics, basically not interested.
Prevailing winds are easterly, the eastern side of the island has rough seas. The north west and western side of the island has calmer seas more suitable to apnea. Flic en Flac is perfect for "free diving", open, deep, and calm seas, but...Not much fish life as the locals decimate the nurseries of anything that moves, occasionally some rays and scattered tiny shoals of fish.
There is a wreck called "Tug-II" that can be visited near the shore line at 21m but unfortunately it's right in the water lane of the speed boat operators, swimming out to it is doable but dangerous due to all the props in the water, hiring a boat or tagging along with a scuba session is the safest way of getting there, but you're on your own once in the water.
The amount of speed boat traffic is unnerving and they don't pay attention, as far as THEY are concerned THEY have right of way, and what do you think you're doing in the water...
I apnea dive off "Falaise Anna" at Flic en Flac, it's easier to access "Two Cannons" and "Tug-II", but do so on my own, basically just play as I can't push my limits due to no safety diver.
I would suggest you hire a boat, go to flat top island and do some snorkling/free diving there, there are fish to see and little boat traffic.
