New NOAA Portal for Electronic Navigation Charts
NOAA now offers a portal to download GIS-ready charts. NOAA makes it very clear that for navigation, one should use the Уreal thingФ via this other portal. The data are available in a variety of formats through what looks like an ESRI-based interface with Safe Software conversion tools. After selecting layers, boundaries and format, (not projection) data is created and can be downloaded in a ZIP file.
