On a naval ship in similar circumstances (in piloting waters), the navigation team would indeed be plotting fixes (visual or radar) every 2 to 3 minutes. If you are running single-handed, you obviously can't manage a proper plot and mind your course too. A shortcut I use is to record my log by speaking into a small microcassette recorder. I transcribe it later. In open waters there is usually plenty of time to manage your DR and EP properly. Regards, Chuck Taylor Everett, WA, USA
