Will You are quite right: the extent of my fishing is trolling. As a naviagtion lecturer I was asked to give a navigation course to a Sub-Aqua Club. Whereas normal navigators prefer to avoid wrecks, divers like to find and revisit them. So their requirements are for accuracy and consistency. GPS is, basically, a fantastically accurate system. With technology you can have almost anything. It is splendid to have an accurate alarm so that you know whether your anchor is dragging. If you can link it to adjacent craft (in case they may be dragging their anchors) and thence by mobile phone to the owner dining ashore it would be even better. Racing folk may find the additional accuracy important though for me, as a cruising man, average speed is more useful than instant speed. I am quite content with GPS as it is! Philip Ouvry
