How To Read A Tide Chart (For Catching Fish AND Boating Safety)

Sail Rock is a notable navigational landmark located between St. Thomas and the Culebra Channel. This small, rugged islet juts out of the water and serves as a crucial point for mariners traversing this part of the Caribbean. Its rocky prominence and isolated location make it an important feature on nautical charts, helping sailors navigate the often tricky waters between the U.S. Virgin Islands and Puerto Rico. Sail Rock's visibility is essential for safe passage, especially in adverse weather
