FoxGlove...read the book, did the trip and met the man in Luperon. Lots of good stuff, but lots of opinion also which you need not follow depending on your boat and sailing preferences and the weather forecast.
Example: The day we left Luperon bound for PR...we had Chris Parker's forecast and knew our boat and decided to go well offshore and cross the Mona passage in one shot. Result...easy passage and no problems. Four boats that left the harbor with us following VanSant's advice all had a rough voyage complete with equipment failures and a lightning strike.
Next time...the reverse might be true. The point is that VanSant is revered as "the expert" and indeed has a lot of experience BUT you are the captain of your vessel and should never make decisions based on one source. I would also warn that VanSant is a resident of the DR and
paints a much rosier picture of conditions there than we found.
