An interesting book, or better an interesting new edition of this Jimmy Cornell classic:
I bought it on the Paris boat show, or better my wife bought it to me and I could not see it properly because she declare that it was my Christmas gift and wrap it up away from me
But it is basically composed with big A3 pages like this one:
A collection for a given ocean or zone, one page to each month.
The data was collected during the last 20 years by NASA and includes winds and currents.
The boat was also some comments about each region, problems, best way and time to cross and so on.
It would be very useful to the ones that are out there or that plan to cross oceans or sail extensively and it would be very useful to improve the quality of dreaming of all armchair sailors
