Did the trip two years ago. Van Sant was by far the best info of the ten or so books I bought. Chris Parker and Herb (Southbound Two) are great. For the Bahamas, the Explorer charts
were much more accurate and easy to use. Didn't stop in the Turks, but from Providenciales, went straight south, shallow (I draw 7 feet) but pretty easy to do, and straight to Luperon. No big weather problems once south of Rum Key. Lots of motoring whenever the window opened. Left Tampa 11 Feb, arrived Trinidad 1 month later.
