Hi,

Hi. Does someone know of a good website with weather forecast, tide
charts and other info relevant for sailboat trip planning in Europe?

For the english waters, check out:

http://www.metoffice.com/

For your way across the North Sea check out:

http://www.dwd.de/de/WundK/W_aktuell/Seewetter/NOsee/Seewetter.htm
(it's in german)

For the ground pressure maps, you may want to take a look at

http://www.mpa-garching.mpg.de/~reinhard/meteo/anakarte.html
http://www.wetterzentrale.de/pics/dwdanal.html

Another good source is

http://www.dmi.dk/dmi/index/
(but it's in danish)

For the rest of the areas you will sail I don't know.

Regards,
Joachim
