Cruise from Placentia among the Cays merged,converted, sketched and published. Re-arranged Central Am box slightly. Now Samarang's tracks in the N are on both WI and box.
Cosiderable puzzling and discussion about CPN first track point....mileage,speed and deletion. Mileage and speed come from ship's present position either default or GPS. but deletion of this spurious mileage is puzzling - not helped by GPSU automatic re-numbering of track points.
