Dreams of Sunsets, Rum & Island Life
Read "advice on books for the VI" on the learning to sail forum. My opinion of your plans is summed up in my response there.
The Belize bible is a book by Capt. Freya Rauscher. I plan on using mine again. Belize is very shallow and can be pretty tricky. Stay away from Belize city as I am told it is a crime pit. The Islands along the barrier reef are fabulous and the natives friendly. Don''t rely on GPS as the existing lat lon on available charts are not accurate.
