Thanks for that.
Just curious. In coming through the Bahamas
about five years ago, we used electronic charts
digitized by Maptech
(and, of course, paper chart backups).
They seemed pretty accurate much of the time. We used them in some tight places for our 6.5' draft
, too, like Mayaguana and Rum
And, as I recall
, when we negotiated the North Channel into Man-O-War Cay, the GPS
positions were spot on. Here they are:

This chart was by Maptech
from a chart by "White Sound Intnl, Ltd" in 1987.
I hesitate to admit it, but we'd gained so much confidence in these "not for navigation" charts
that we actually negotiated this channel through the reef in darkness -- on a very, very calm night and under power
-- with crew stationed forward and on both sides with searchlights into the water
to be sure we stayed in the channel. After a few days stay in Marsh Harbour, we reversed our course and again -- this time in daylight -- found the charts to be quite accurate.
Wonder what others have found in this regard?
