There's no definitive answer to this question as it largely depends on what you're looking for in a boating destination. However, if we're talking about the overall boating scene and facilities available, then it's safe to say that Florida is the boating capital of the US.
With over 11,000 miles of coastline and countless inland waterways, Florida has something for every type of boater. From world-class marinas and dockside restaurants to secluded anchorages and pristine beaches, you can find it all here. And with year-round warm weather, it's no wonder why so many people flock to the Sunshine State when they're looking to get out on the water.
If you're more interested in competitive sailing or powerboating, then Rhode Island might be a better fit for you. The state is home to some of the most prestigious yacht clubs in the country, as well as a number of annual regattas and races. Newport is especially well-known in the sailing world and has hosted events like the America's Cup in recent years.
