I have agreed to help produce a marine map of the Baltic so it would be really nice if the sea was filled in without any really major problems (flooded land, etc.)
I, unfortunately, can't help you specifically with the generate sea stuff. I can only comment that my previous tests with this option were not particularly satisfactory. Since distinguishing land from water seems to be an important feature of marine maps, I wonder if it makes sense to generate a one-off sea layer using cGPSmapper instead of mkgmap, until the generate sea problems are resolved? Or do most marine units have a sufficiently detailed base map? In that case a transparent OSM map (with POIs and other features) might be more appropriate, as this could be layered over the base sea map. Cheers.
