Tampa Bay Crossing Cross the open waters of Tampa Bay east-northeast from the water near Spa Beach and St. Pete Pier in St. Petersburg towards the northern shore of Apollo Beach Nature Park. The straight line stays south of Pine Key and the larger spoil islands, with no intermediate stop shown. This approximate reconstruction retains the two endpoints visible in a map image, not an original GPS recording. It measures about 20.35 km, compared with 20.59 km in the image and the rounded 21 km listing. The start remains offshore rather than at a confirmed beach access, and the finish is an approximate water-edge point, not a verified landing. A long open-bay crossing can encounter commercial traffic, currents and rapidly changing weather; confirm navigation rules, permitted shore access and a suitable local passage plan independently.
