G'Day Mike and Paddlewise, Thanks for that it certainly got me thinking. But I have some questions on terminology applied to our "navigation exercise". We were using crude angular measurements (eg kamals and thumbs) to compare height and horizontal separation of land marks to estimate distance travelled, timepieces and an assumed speed to estimate distance travelled, compass bearings to landmarks to compare against precalculated chart measurements to estimate position and speed through the water. Was this pilotage, dead reckoning or coastal navigation, or all three? We used the GPS, i.e timepiece based distance and angular measurements to satellites to check our position against a chart. Would this be regarded as celestial navigation? Also I'm unclear about the differences between celestial navigation and navigation. Also to what extent is the word pilotage mainly used to describe guiding ships into harbour as opposed to coastal navigation which seems to be used to describe pilotage to find your way along the coast? All the best, Peter *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
