On 29 October 1969, taking the chair at a Duke of Edinburgh Lecture, the great educator Lord Butler commented, ‘…in my view, it would do a great deal of good if navigation could be considered an educational subject’. Indeed, we know that by 1700 the discipline was being taught in ordinary schools in this country, and it is perhaps worth repeating Isaac Newton's remarks on the Christ's Hospital syllabus: ‘he that is able to argue nimbly and judiciously about figure, force and motion is never at rest until he gets over every rub’.

The inclusion of navigation in the curricula of schools during the 17th century was for financial rather than for educative reasons. In those days, the master of a ship was responsible for its navigation and invariably had a stake in the marine enterprise. Thus he might make a small fortune in a single voyage. By 1800, the introduction of the limited liability shipping company and the growth of marine insurance were beginning to relegate the captain to the status of a hired servant paid the minimum wage. Navigation rapidly disappeared from ordinary schools and was taught only in the specialized nautical establishments. Nevertheless, it is worth noting that today, the mariner, the submariner, the pilot and the astronaut have restored to the subject its original lustre and the yachting explosion has given the discipline a wide appeal.
