Wow, this is a very old thread subject going all the way back to 2004 and seems to get a new entry once a year or so. Is there anybody out there that is still - today - looking for raster e-charts of the Bahamas, Caribbean
, etc.? Or is this just a perennial floating discussion?
I have a huge library of about 14,000 e-charts of basically the whole world which I won't mind getting rid of to somebody who can actually use them. They are in the ancient Maptech
, BSB, Softchart (geo) and other formats that I have been able to access and use with my ancient "Cap'n vers. 6" navigation program running on a Win7 lapbook computer just fine.
As to accuracy of these type charts - don't bet your boat on it. Most of the data is from WWII surveys and some all the way back to Capt Cook's data. Updating is a non-starter as the areas cruisers go is of no-commercial interest to major navigation providers. However, the Earth really doesn't change all the much in 50 to 100 years so the topographical outlines and hydrographical data shown is useful when compared to "no-data." As always, the old Mk-1 eyeballs are the best navigation tool available to a cruiser and having a basic outline or idea of the layout of your target destination
with these charts helps quite a bit.
