Rauscher's guide is very good. Be aware that chartplotters lie in Belize. Our
charter boat had a
raymarine plotter and I had my
Garmin handheld. Neither was entirely accurate though the
Garmin seemed a bit better. The problem is that the
charts they are based on havent been updated in many many years. I had the Admiralty paper charts also (the best for Belize) and some
parts of them dated from lead line surveys in the 1840's! But the waypoints in the Rauscher guide were spot on, at least all the ones I used.
