Boating
Owning a boat in Florida is almost as neccesary as owning a car.  To get to the best fishing and dive spots you must have one of these.  The boating industry is constantly increasing causing more boat traffic than ever in certain parts of Florida.
Boating allows you to explore  areas that are unaccesible by land and find some excellent reefs to dive.  This is a definate "must have" if you live in Florida.  "Let the Buyer Beware," boating can be very expensive, especially in repairs. Saltwater and engines don't mix very well.
