We chartered Wind Dancer two years ago. Took her down to PSV and back to SVG in 10 days, close hauled both ways.

Dawn - drop me your email in a PM and I'll send you the very lengthy trip report from the first half of the trip. I have not finished the full trip report, but you would learn a lot about Wind Dancer from it.
In 2010 Wind Dancer was a solid boat in good condition.
She'll sail much closer to the wind if you use the vang well and haul the traveler car to the windward side of the boat. She'll do about 100-degrees tack to tack like this, at a speed through the water of about 5.5 knots. Cracked slightly off the wind (from being closed hauled) she jumps up to 6.5 knots.
