Works with Trail Boss version 2.52 and above.

Warning, this is not an official map.The nautical information contained in this map is created and maintained by a user community, not official government sources. The charted objects may be inaccurate, outdated, or just plain wrong. Do not rely on this map for navigation.

This map does not have coastlines or land features. As such, it used as an overlay on top of one of Trail Boss's main maps. To use OpenSeaMap, first select the Trail Boss map you want to use as the base map (such as Streets or Satellite) then select this map.
