Thomas Benoist, an auto parts maker, decided to build such a flying boat, or seaplane, for a service across Tampa Bay called the St. Petersburg - Tampa Air Boat Line. His first passenger was ex-St. Petersburg Mayor A.C. Pheil, who made the 18-mile trip in 23 minutes, a considerable improvement over the two-hour trip by boat. The single-plane service accommodated one passenger at a time, and the company charged a one-way fare of $5.
After operating two flights a day for four months, the company folded with the end of the winter tourist season.
