We love the massive turn buoys used in Brazil.

They are big, they are easy to see, they promote the sponsors.

Because they are so big and easy to sight, when the currents are flowing especially laterally (either perpendicularly or diagonally to the turn buoys), swimmers can easily modify their course to take advantage of the currents AND hit the buoys right on.

Pedro Rego Monteiro and his colleagues at Effect Sport design some of the best-looking, largest and most visible turn buoys on the open water swimming seascape.
