Automation & Technology: Dulling Mariner skills?

22.05.81

I recently attended a STCW-mandated BRM elegance on the East Coast. The instructor – a wisened, well respected gentleman Master Mariner – told us a risible story about how, back in his day (even before mine), when the new Third Mate went up for his first day watch on the bridge, the old man would take a black felt-tipped pen and liberally coat the hood of the Radar component before departing for his cabin. At lunch, everyone (except the Third Mate, of course) would know what the youngster had been doing for the better part of the last four hours. His wholly, of course, had been jammed in the Radar (instead of looking out the porthole in crystal clear weather) and his raccoon eyes gave him away directly. Now, in 1975, I’m sure, that got a good laugh in the officer’s saloon and the Third Mate was later meekly counseled about the need to spend more time keeping a traditional lookout, especially when the conditions so warranted. Today, I presume, that prank might invoke some

Explain how to use a sextant and a chronometer to determine your latitude and longitude?

Mar 14, 2010 by Jess | Posted in Geography

My lecturer wants to know how you can use a sextant and a chronometer to determine latitude and longitude during a cruise through the multitude of the South Pacific. She says that we can draw a sketch to help with our explination.

You can use a sextant to more the angle between a star and horizon. Imagine you are at the north pole. If you looked up, you would see the North Star.

About this book
Loran and GPS notwithstanding, there will always be a place for the sextant aboard any blue-water boat, if for no other reason than the thrill and mystery of finding one's position on earth by gazing at the heavens. Here is the indispensable reference that should accompany the instrument aboard. Cmdr. Bruce Bauer, a professional navigator and master mariner with the U.S. Merchant Marine, has distilled years of hands-on experience into an eminently readable guide to buying, adjusting, using, and repairing sextants.The Sextant Handbook is dedicated to the premise that electronic navigation devices, while too convenient to disregard, are too vulnerable to rely on exclusively. The book is designed to make beginner and expert alike conversant with this most beautiful and functional of the navigator's tools. Topics include:Assembly and DisassemblyVital AdjustmentsAvoiding ProblemsRough Weather SightingsOiling and CleaningImmersion BathsEmergency SilveringFinding and Buying Used SextantsAnd Much...
