There's really not much different in the laws FL. USCG Rule 6 is a great place to start. From there, just know the local rules for PFD use, towing skiers and other devices, and the aforementioned 150' rule. The navigation is a little different on the lakes. Most of it can be found at this site,

Nothing real weird or mysterious. The USPS course is far more extensive, and one that I would recommend everyone take. For new boaters, Probably the very best training can come from a friend or boat dealer, ON THE LAKE.
