Updates


Updates are necessary either to note changes that have occurred since the time of publication or to correct a typographical error. We make our best effort to make our readers aware of any updates.

Note: With the exception of the error on page 75 (waypoint BC175), the errors noted below are typographical errors and do not affect the waypoints in "Proven Cruising Routes on Disk".
