There are over 7000 named lakes in Florida, many of which are within an hour's drive of Orlando. A lot of them are quite shallow (e.g. Lake Apopka, the largest lake just NW of Orlando), and others are down because of our 3-year drought. But, some of the best sailing lakes in the state are also nearby. My two favorites are Lake Harris and Lake Eustis, both just to the NW of Lake Apopka. Lake Eustis has the Lake Eustis Sailing Club (http://hometown.aol.com/tomkidd/LESCindex.html), which hosts one of the nicest multihull regattas in the fall. Lake Harris has a park S of Tavares on Rt 19 with excellent launching and parking facilities. As CatsailorP19MX said, Tampa Bay including Gulfport at the southern tip of St. Petersburg and the Dunedin Causeway to the north is a bit longer drive but are both excellent sites. The Davis Island Yacht Club is a little closer (30-45 minutes) to Orlando, and is sited at the southern end of Davis Island in S. Tampa on Hillsborough Bay. There is very good beach and boat ramp just before the yacht club, and the yacht club ("The Sailingist Yacht Club in the South") has been the host of many good multihull regattas. It is definitely not a snooty YC. On the east coast, Cocoa Beach is close. Hobie Fleet 45 (http://www.members.tripod.com/~fleet45a/fleet45.htm) says that "Fleet 45 sails from Kelley Park on the Banana River just south of SR 520 and the Indian River (Intercoastal Waterway) from Pineda Causeway. Fleet sailing events are held on a regular basis from a beautifully protected wide body of water just a mile inland from the ocean." You might also check out the NAHCA Division 8 web site for other contacts (http://flsail.home.att.net/fleetinfo.htm).

Good luck and enjoy your vacation. Hope you have time to sail with the the family at Disney.
