The boats can typically travel at speeds over 80 knots (150 km/h) in calm waters, over 50 knots (90 km/h) in choppy waters, and maintain 25 knots (47 km/h) in the average five to seven foot (1.5 to 2 m) Caribbean seas. They are heavy enough to cut through higher waves, although at a slower pace.
Sharks typically swim with the even, liquid grace of a creature completely at home with its place in the Universe. Large sharks generally cruise at a leisurely 1.5 miles (2.4 kilometres) per hour. Because most species fare poorly in captivity, the maximum swimming speed of a shark has seldom been measured. The Blue Shark (Prionace glauca) is an open ocean glider, planing on wing-like pectoral fins and flattened belly.
