- Have you ever seen a *Pilot Handbook *or a *Light List*? ... The Light List gives you exact details of every navigational light in an area; height of light; on a pole or is it a buoy? Color? Markings? All the information you need to make a positive identification of a particular lighthouse; or harbor entrance navigation lights, and their exact location.
Some lights info is often on the charts - and includes angles of view of the light, when they have restricted angles of view. At night one can navigate by finding position and/or following a course based on the lights visible, and what to look for next. It's very cool actually. I have only experienced a whole passage like this once, very long ago, but it was darn exciting, sailing along in the starlit dark in between islands in the Stockholm archipelago, being shown on the chart where we were, what lights showed our position, and what light(s) to watch for next and where, so we'd we stay on course and in suitable water. It was also cool that the passage was on an old (1930's or thereabouts) wooden Scandinavian lake cruiser type boat, long and low and narrow, with full keel, wooden spars, etc. (one of my "Old Country" Swedish-Finn cousins was living in Stockholm at the time and her then-boyfriend, a British expat, was the boat owner/skipper). Not quite so long and thin, nor nearly as highly polished, as this example, but you get the general idea: https://c1.staticflickr.com/3/2438/3618674531_4c248b3df2_b.jpg cheers, John -- John Schinnerer - M.A., Whole Systems Design -------------------------------------------- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john@eco-living.net - 510.982.1334 http://eco-living.net http://sociocracyconsulting.com
