I have to respectfully disagree with colemj. The Zydler guide is far and away the best cruising guide I've ever used. All his hand-drawn charts
are completely accurate, and his soundings and directions as well. It is not for those who wish to simply plug
waypoints and routes and follow them, (which is what the Bauhaus guide is all about) but for those who rely on piloting and eyeball navigation
(which is safer, to me, than following a 50-waypoint route
through shoals). I guess it comes down to a matter of style, but the Rauscher guide to Belize
also requires eyeball skills, as do certain harbor entrances in Honduras
. Anyway, by all means lay hold of a Zydler guide. It's a great resource.
