PLIMSOLL is the name given in general terms to all footwear with rubber soleS and canvas upper. In the 1890's Dr.Samuel Plimsoll, a victorian engineer invented 'The Plimsoll Line'. This was a system devised to control and limit the volume of goods onto ships. Many unscrupulous ship owners at the time were overloading their vessels, resulting in numerous sinkings with the inevitable loss of cargo and lives. His system was a series of lines on the outside of the ship to indicate how loaded the ship was. It was extremely unpopular at the time as it meant ships were carrying less goods and therefore making less money. However the system still survives to date on many vessels and whilst Dr.Samuel Plimsoll's reforms lead many to view him in his lifetime with disdain he is now commemorated with a bronze statue on the embankment of the Thames for his services to furthering the safety of shipping across the globe.
