How big of a boat would you have to have to start a business in diving and about how much would it cost?

Question

I am very passionate about diving and am on my way to becoming an instructor. Obviously it would help a great deal if I was to get a boat. I would probably have around 6 people on it. I would also need room for tanks, and gear. How much would that cost, it is also in Hawaii if you need to know that information. I know they make everything more expensive here then it is on the mainland. So thank you very much for your input, anything and everything will be appreciated.

Answer 1

over forty feet would be reccomendation and it would cost as much as a car.
