Dear Bart.

I suspect that your data, even if readable by Arc-Info, may not be in
Arc-info format. This is important because Grass has a couple of import
routines that might deal with that.

If your elevation data is a raster DEM or DTED, correct me if I am wrong,
there are chances that the programs m.dem.extract and m.dted.extract might
do the trick.

For the bathymetric data, i don't know, since there is no indication in your
message about in which format the data REALLY is.

But then, I may be way off line...
