Back to our home port area, the charts still show a little island that washed away back in the mid 70's! We have a lot of chart "features" like that here in SW Florida. The approach to Marco Island is one example. Coconut Island has been completely gone for some time and a GPS track for the channel takes you right over the top of it. A GPS track coming out Red Fish Pass north of Captiva Island goes over dry land also. Fortunately the nav aids for both of those places are accurately set because anyone following the chart will get in trouble. I've got (if I haven't misplaced it) a chart of some of the islands in the S. Pacific with the notation "based on the survey by HMS Beagle, 1776", or some such wording. I wonder does the coordinates agree with GPS? Cheers, Bruce (bruceinbangkokatgmaildotcom) |
