Electronic charts

Ever since man first went to sea there has been a requirement for some form of recognition of the seagoing environment to assist in the safe passage to the required destination. Knowledge of the coastline, safe channels for navigation which avoid wrecks, sandbanks etc., and tidal information all play their part in assisting the navigator. Paper charts giving information about particular areas have been around for centuries and hydrographers from various countries have explored the world’s oceans to produce up-to-date charts which are an invaluable aid to the seafarer whether they are aboard commercial vessels plying their trade around the world or leisure craft sailing for pleasure and recreation.
