TexasBill, for information, there are some updates and some sailing guides.
His 017 Hispaniola Chart
And this is more or less the state of digitization of nautical charts for the area - with emphasis on the nearshore shallow regions. So, there is better and updated data available.

I'll stick to what I said .. talk to many sailors before you go sailing around Hispaniola. If we are dealing with an experienced sailor, they will know what to do. Also, a fairly good description of the conditions and how to tackle them in The Gentlemen's Guide - more North Coast focused. There are some new South Coast Maps and Sailing Guides.
