Most dive clubs that I’ve seen do not "officially" register as a company. They just agree to get together to form friendships, organize dive events, get group discounts, etc.
Unless you plan on paying your club officers or raising money, I don’t think it would benefit you to start-up a non-profit.
As far as liability, maybe you could require all new members to have dive insurance before they can attend dive events. OR have members sign an agreement stating that the dive club is not responsible for them.
