After having some difficulty loading raster NOAA Nautical Charts into Grass Gis, I came across this page Converting NOAA raster charts to GeoTIFF for TileMill
I was not able to load the .KSP files for the NOAA rastermap (#12363- Long island Sound) into Grass GIS, with r.in.gldal despite its ability to handle .KSP files, but converting the files to GeoTIFFs first and then reprojecting worked perfectly. Determining the ESPG number was not readily apparent- as a workaround- I loaded the projection data (.prj) of an existing shapefile already existing in the Grass location into Prj2Epsg which returned a ESPG number of 4267.
1) Covert BSB to GeoTIFF
gdal_translate -of GTiff 12363.KAP 12363rectified.tif
2) Reproject GeoTIFF into final file (12363rectified-reprojected.tif) using gdalwarp and the EPSG number
gdalwarp -t_srs EPSG:4267 12363rectified.tif 12363rectified-reprojected.tif
3) Load final file via Grass GUI as you normally would.
The result is below- a NOAA rastermap overlain with vector bathymetric data (blue lines)

Its a evocative storyline with appealing maps and charts telling the story of Connecticut's changes in land use and how it affects natural areas and resources Some interesting tidbits from the presentation:
- Turf and grass now cover more of Connecticut than agricultural fields.
- Between 1985 and 2010, 29,661 acres in the riparian zone were converted to developed or turf & grass.
- In 2010, CT had 1716 watersheds with impervious cover levels indicative of poor watershed health, representing over 25% of the 6851 local basins in Connecticut.
