The Golfo San Matías is nearly enclosed, which is why it heats up in summer and why Argentines drive a thousand kilometres to swim in it. The wrecks are mostly fishing vessels lost in the last fifty years, some deliberately placed. Anchorage: The Golfo San Matías is a huge sheltered gulf, and San Antonio Este is the working port. Hazards: One of the largest tidal ranges in South America, so everything is planned around the tide. Meer
