A terrific t-shirt is sold in tourist shops at some of our nation’s harbors. It has a “definition” of a nautical chart splayed across the front: “chärt, n: a nautical map that shows you what you just hit.” It’s funny… but unfortunately, too true too often.
Resolve to get your nautical chart this year and consult it before you hit something. Advancements in Coast Survey’s digital processes now allow us to review and update charts weekly, and get them to boaters’ fingertips faster − and with less expense − than was possible years ago.
So, what product is best for you? Check out the options…
Paper nautical charts, printed “on demand.” Coast Survey maintains 1,025 nautical charts and provides the digital chart images to NOAA-certified agents, who print the latest version (incorporating weekly updates) when you order it. Order from any of our print agents – several with distribution to local marine shops – that offer different papers and optional premium services.
Free PDF nautical charts. Almost all nautical charts are available for download from our map-based interactive chart catalog or the numbered list. Crop, re-size, print or display them. (Just don’t use them for navigation if you are a SOLAS vessel, since regulated vessels need charts from NOAA-certified printers.)
Free BookletCharts™. For easy printing at home, choose NOAA BookletCharts. These PDFs have the same information as the regular paper charts, but they are sliced and diced into 8 ½ x 11” pages, so you can keep them in a regular notebook. Some boaters like to slide the pages into sheet protectors to protect them from the spray.
Free raster navigational charts. The NOAA RNC® is a geo-referenced digital image of the paper chart, used in a variety of commercial electronic charting systems.
Free electronic navigational charts. The NOAA ENC® is produced from a vector database of features. It supports real-time navigation as well as collision and grounding avoidance. ENCs are used by many computer navigation programs and mobile apps, as well as ECDIS.
Free historical charts (in jpg). Reflecting Coast Survey’s beginnings as the first scientific agency in the U.S. government, the Historical Map & Chart Collection has nearly 35,000 images of nautical charts, topographical maps, sketches, and more.
Okay, you’ve decided which product you want. Now, what chart do you need?
Coast Survey’s map-based interactive chart catalog makes it easy to find and download the chart(s) you need.
Chart catalogs are handy to have around. (Note: Coast Survey is transitioning from the large format to an easier 8½ x 11″ PDF catalog that you can print at home. Some of the catalogs are beginning to appear on Coast Survey’s website now, with all five catalogs scheduled for completion by the end of June.)
More information is available to make your trip more enjoyable.
The United States Coast Pilot® is a nine-volume book series (geographically based) that contains a wealth of information: regulations, facilities, weather, prominent features, radio procedures, currents, small-craft facilities, and more. They are now available as free PDFs, or you can purchase hard copies from NOAA-certified print agents.
nowCoast is a map-based portal that provides one-stop access to coastal observations and forecasts.
Coast Survey’s wrecks and obstructions database provides latitude and longitude on thousands of wrecks along U.S. coasts and in the Great Lakes, along with some historic and descriptive details (where available).
Does a chart have wrong or outdated information? Report discrepancies.
Seafloors, channels, shorelines, and aids to navigation are constantly changing. Coast Survey applies corrections to charts and the Coast Pilot every week, but we need the public’s help pinpointing changes in the 3.5 million square nautical miles of U.S. charted waters. Report charting discrepancies.
Have a happy and SAFE boating season!
