It is! Jochens blog gave me the idea to use sea information from another source (don't reinvent the wheel :-). I tried but didn't succeed to run Jochens new program. But it would be very good to use his new approach. The precompiled mapnik sea files have a big disadvantage: the land areas overlap and this has to be removed by the mkgmap precompiler. This is very expensive and requires a long time (maybe some optimizations are possible for that...)
