Forged by the sea: America's Navy.
Cruising Through Panama Canal at Night
2014 - HMS Protector took seven hours and 38 minutes to make the 77.1km (48 miles) passage from the Pacific to the Atlantic through the canal, which this year marks its centenary. The 18-metre wide vessel travelled at an average speed of 7 knots through the canal, which at its narrowest point, measures 30 metres. The canal, which is 26 metres (85ft) above sea level and has locks at each end to lift ships up to the artificial Gatun Lake, shortens journeys by thousands of miles.
