Interesting and informative text, indeed. Thanks for posting
I like your idea of making a table with extracts from GRIB data at given points.
Actually, I use such a tool built in the framework of OpenCPN Route
Properties. It has some more capabilities, but this table is its only feature I ever use in real planning. It puts together the basic data for each waypoint: ETA, state of daylight, state of the tide, true wind
and point of sail. It also can handle the sea currents data, if included in the same GRIB, but these are not commonly available.
I also use a simple polar speed diagram, mostly to show when motoring is to be expected (in this example, speed 5.11 is motoring speed).
Simple but useful...
