I've used Hustler several times for diving and would highly recommend them and I using them again in May.
What a lot of people don't realize is when they book a tour (note that I said tour, not diving) with a company it may not be the actual tour operator. Hustler may have booked the tour, but the boat and guides may have been part of another operation.
This is very common on AC for tours. I don't have all the facts on this particular trip but just wanted to let people know so generalizations and accusations are not loosely thrown around.
