    Re: NO 9xx plotting sheets

    Thanks, Greg!    Interestingly, what they are selling is a printout from Ocean Grafix, the company that pioneered print-on-demand charts (and I suspect is doing quite well now that NOAA is stopping printing paper charts).

    When I went to the Ocean Grafix web site and found the chart, I clicked on "buy"   It sent me to a franchisee that did NOT carry the chart.    Only when I clicked a second time did it send me to Nautical Charts On Line.

    Some who replied sent me to sites that carried basically a 8-1/2 x 11 plotting sheet that is intended to cover a single degree of latitude and longitude.   GREAT for plotting a reduced sight vs one's DR position.   But if one wants to do a multi-day track, one would have a hard time using these sheets as opposed to something that covered multiple degrees on a "chart-sized" chart.

    There are no large scale charts of the middle of the ocean, so if one is going to keep a reasonably detailed navigation plot (DR, GPS fixes, celestial shots) one needs some sort of plotting sheets.

    A long time ago the US Navy's Hydrographic Office produced a series of charts which were basically blank Mercator charts covering 3 degree intervals of latitude and 3 to 6 degrees of longitude depending on latitude.    For example, NO973 covers the band from 38 deg to 41 deg.   (I'm looking at a NO973 from a celestial course I took in the mid 1980s)

    What's happened to these plotting sheets?   I can't find a source for them despite some fairly extensive web searches.

    More important, what do people use today instead of these charts?
