Variation is either 10 or 11 degrees W on Lake Ontario...it's hard to screw up if you have even half a clue about reading a chart. I'd suggest logging what info you can .... true, mag, var, dev, compass, courses steered, courses made good, and any azimuths (land or celestial ) which you can or may be able to take. I do this when necessary on a scratch pad next to the compass or (when raining) on a "magic pad" from a dollar store (the grey plastic covered rewritable things from Way Back...perfect for wet weather!) I transfer any "summation" to the log, but in Lake Ontario, it's 95% coastal pilotage and there's only a few places with shoals, rocks and big chunks of iron under the boat...Deviation and variation are known and compensated for on the fly. In blue water or unfamilar waters, I would make further notes. This makes for good historical data, especially on repeat trips over the same ground. True. I have little pieces of tape at 45 degrees fore and aft to where I stand for the tiller. That and a stopwatch and the knotmeter give me a way to tell how far offshore I am. If I pass close by a buoy, using the same method, I can judge my speedo and current, if any. As I don't tend to sail more than five-10 miles offshore, I use the GPS primarily to confirm visual pilotage (is that the landmark on the beam that I think it is?) and to confirm COG readings for set and drift (not a big deal here, usually) and ETA to destination. My wife uses the ETA function to remind me when sailing is over and motoring must begin G. I log that in "Comments". R. |
