The raster nautical charts were first reprojected from their original projection/datum to UTM Zone 4, NAD 83 using NOAA's Nautical Chart Reprojector v1.8.3.

Subject areas were then digitized off the individual nautical charts and merged into a single dataset/shapefile which covers the entire state. Completed December, 2002.
