Sailing ships in 1609 do not have engines or motors, oars, or GPS. They are entirely at the mercy of the wind, waves, and tides. The ships sailing in the Atlantic are square rigged rather than triangular lateen rigged as is often the case in the Mediterranean Sea. Square rigged sails do very well when the wind is behind the ship. Because the Atlantic Ocean had steady wind patterns, this was an advantage. Triangular lateen rigged ships are more maneuverable but much slower when there is a steady wind behind the ship.
