Caribbean Reefies contribute 94% of total revenues - source.
Read this paper!
Shark Diving in the Bahamas is worth $ 109m per annum.
That is great - but it could be a lot better.
Turns out that owing to those foreign liveaboards, approx. 50% of potential domestic revenues are lost in Bimini, approx. 85% in Cat and a whopping 97% in Tiger Beach - and more money is being lost to those mooching film crews that barge in without the required shooting permits.
No wonder the BDA wants those foreign vessels gone.
Anyway, great paper.
