On my chart plotter the entry into Spanish Waters in Curacao put me in the Hyatt Hotel swimming pool and the Boca Grande entry into Cartagena placed me on the reef.
Where I am now moored, Puerto Morelos Mexico it is out by 800 yds.
I use my chart plotter as a general reference and guide to supplement paper charts and guide books.
However, the one thing I do not use it for is accurate navigation...The more I use it the less I do night entries.
Sailingdog has it right...If you can't eyeball it you should not be doing it. Unless your charts are good and up to date and your charting/piloting skills are exceptional.
And Oh yes, never, never cut corners on buoyed entries and channels.
