Wet finger in the wind works well on wind direction ..

I really liked the qualities of the Ordinance survey maps of the British Isles , but not being my first roadeo,
as soon as I bought them , Id Lay down a strip of clear packing tape where they were folded ,

Seems people use a car GPS on their boat then run the keel into the bottom , and hole the hull
because unlike the NOAA Nav Charts there is no information of what is under the water.

Norway Krisiansand, to Hirtshals to Esbjerg is the 2 danish ferry ports you have in mind, or Sweden, via Goteborg to Fredrikhavn ?
