CAPN Marks

We plan all our trips using Star Technologies  "The CAPN" product in concert with various Cruising Guides.  Over the years, we have refined the process to include overhead satellite photos of all the waypoints in those Cruising Guides.  These are available here as free downloads, no strings attached,  for the personal use of fellow Cruisers.

What you get:


We have only produced files compatible with "The CAPN 8.3"; they may work with other CAPN versions, but this has not been tested.  CAPN allows users to store route waypoints and marks in a manner so that they superimpose on the charts being displayed.  Although the CAPN does not distinguish a difference, for clarity, we refer to Waypoints as being leg segment ends in a route, and Marks as simply points of interest.  The Marks that we allow you to download have been developed to exactly match the information in the Cruising Guides.  Very few discrepancies were found and those have been corrected and reported to the Author's.  We support Cruising Guide authors by purchasing their publications, which contain a wealth of information beyond simple waypoints.  You should use up-to-date Cruising Guides to get the best use of our CAPN data.

Each CAPN Mark is named, tied to an area code and linked to a Guide.  The exact Latitude and Longitude, as provided in the Guide, is used along with guide page numbers to quickly refer you to the author source.  Marks used bear different symbols to indicate marinas, buoys, etc.  By right clicking on any Mark, you can get detailed textual definitions and more importantly, you can request the "Photo."  The photo option brings up a box containing a Google Earth satellite overhead, where upon the Mark is shown at its actual geo-coordinate location.

In some instances, the Lat / Long and photo may not agree with the chart displayed location.  This is because some charts are not correctly aligned to WGS84 datum or the projection used to produce the base chart produced a distorted land approximation.  We have learned to trust the Author's input, especially since their stated locations correctly align with the satellite overheads.

Most of the Google Earth photos are fabulously detailed and bring the cartographic data to life.  Again, Google does not guarantee accuracy or quality of this public domain data.  In some instances, the photo may be blurred or the area is obscured by cloud.  We have used North Up orientation and tried to pick an appropriate viewing altitude.


Every Cruising Guide written states that the waypoints contained therein are not to be trusted blindly.  We repeat those warnings here, that the original source data may be wrong and our transcribing them into CAPN format may have introduced errors.  Having checked the Guide Author's waypoints against the Google Earth satellite data, there is a high degree of probability that they are good - but
YOU are completely responsible for insuring they are safe to use for navigation with any intended vessel.
