I'm reading Herbert Werner's Iron Coffins (great read, btw) and he mentions that U-boats were given a grid-square to patrol (like BE 81), how big were they?

I tried searching on the net, but couldn't find any info...

Are there links/maps that show those grid squares around the world?

Thanks guys - sorry if this has been covered already.

Not sure if this will help but here is the ingame grid map. Each grid area is broken down into smaller partitions to be able to have a four digit reference, e.g AM3987

Also check out Kartengruppe's homepage http://www.kartengruppe.it/. He has a lot of interesting charts etc relating to the WW2 era.
