I believe that it is timely that Dr. B. D. Yallop, Head of HMNAO, has responded to criticisms and the discussions surrounding the inclusion of ‘Sight Reduction Procedures’ and ‘Sight Reduction Tables’ beginning with the 1989 edition of the Nautical Almanac. As my name was mentioned by Dr Yallop, I would like to set out my own views on some aspects of those discussions because I believe that both the ‘theoreticians” and the ‘practitioners” positions have become too polarized.

Electronic navigation systems are now well established on commercial vessels throughout the world. In a big ship it is entirely feasible (and probably necessary) to design the system to suit the ship. Budgets are large and there are few space constraints, so that many separate displays may be used on a bridge which would not look out of place on the USS Enterprise. This is definitely not so for a small sailing cruiser or powered leisure craft. Neither is it true for many fishing vessels. It is to those with an interest in these small boats that I address this paper.
