Photographer’s Note

Another photo from a journey through the Panama Canal in 1970 and my second posting of an unforgettable day.

This photo was taken as we approached the Miraflores Lock which is a two chamber lock and the first set of locks on the Pacific Side. The single chamber Pedro Miguel Lock follows and completes the process of lifting ships from the Pacific up to Lake Gatun. On the Atlantic side the three chamber Gatun Lock lowers ships to the Atlantic. All three sets of locks are paired - that is, there are two parallel sets of locks at each of the three lock sites. In principle this allows ships to pass in opposite directions simultaneously - however large ships cannot cross safely at speed through the narrow Calebra Cut, so in practice ships pass in one direction for a time, then in the other, using both lanes of the locks in one direction at a time. Water enters and leaves the locks by means of gravity only - there are no pumps or other man made devices that assist in this process. For large ships assistance is provided by electric cars (mules) which run alongside both sides of the Canal attached to the vessel by long cables. These mules help guide the vessel through the locks - but the ship at all times moves under it's own power.

This photo was taken from the 'Australis' of the Chandris Line which from 1964 to 1978 regularly carried British migrants from Southampton, UK to Australia - and on its return journey carried young Australians and New Zealanders who were eager to experience to Europe.
