Download chart files in MBTile format for
use with OpenCPN and other charting programs.
MBTile is a file format for storing tilesets. It's designed to allow many chart files to be packaged into a single tileset.
A tileset is a collection of raster or vector data broken up into a uniform grid of square graphic tiles at 22 preset zoom levels.
MBTiles have many advantages over the older KAP format. They support more colors, are smaller than KAP files, and many tiles can be contained in a single file.
Share these files with others but please only share the downloaded files (along with this readme file or a link to this page that you are now reading). That way others who want to download the files will do so knowing everything they need to know (and be able to read the warnings!). It will also give them a chance to donate to a great cause.
Thanks for helping out.
It’s up to you -- not these files or the people who made them -- to keep you, your crew, and your boat safe. We did our best with these files, but we make no promises.
Always use multiple sources when navigating -- including your eyes looking at the real world, not just a chartplotter.

Because social media is harming society and cruising. The incessant monetizing and merchandising of the cruising life detracts from its beauty and community. We appreciate the hundreds of people who helped us learn by simply giving freely of their time and experience.
Vloggers, stop trying to be famous and just sail already. And please stop cheapening this wonderful life with your false, reality-TV, over-the-top approach; it's cheesy and juvenile. And those who support them, there are so many more worthwhile causes. Really.
