Every town needs a hot dog boat captain

You’ve thought about it. What if you could combine an ice cream truck and a pontoon boat? The result might look something like Jim Napolitano’s “Crazy Cajun,” a faux steamship that sells ice cream and hot dogs on the Chain O’ Lakes in Illinois.

He’s run the floating restaurant for the past three years — and don’t scoff. Another small operation that started on a boat, delivering fresh juices for boaters off the coast of Nantucket, grew into Tom First and Tom Scott’s Nantucket Nectars. Just a little over a decade later, their beverage company was sold to Cadbury-Schweppes PLC for an estimated $100 million. Nantucket Nectars is currently owned by the Dr. Pepper Snapple Group.
