Hi John, happy new year! 🙂 Found this via your new “Navigation” book, thank you for sharing.
Would you mind elaborating on how you use the various columns in your log? Some of them are not clear to me, for example:
– What do you put in the “Log” column?
– What do you put in the “Distance” column? Is it distance covered since last log entry? Is “Water” value obtained by time elapsed * estimated average speed (via knotmeter)? Is “Ground” distance over ground? Are you using GPS for this, or computing via the delta latitude & longitude since last log entry, even in the case of an estimated fix (dead reckoning)?
– What is the “Bar” column, atmospheric pressure?
Thank you, I love to learn how other folks do things and get ideas.
Chuck
Hi Chuck,
Sure:
Log: Distance measured by the log rotor (through water).
Distance: Difference between two log readings (water). Distance on chart between two plots measured with dividers (ground). This is left over from when we plotted on paper. Difference tells us what current affect is.
Bar: Barometric pressure.
More here on plotting with updates on modifications we have made as we transitioned to electronic plotting: https://www.morganscloud.com/2010/03/23/old-and-new-styles-of-marine-navigation/
