How quickly did you escape the crazy weather up there?
We've had no experience with either of the two places, so can't help you there. The Jaxville yard is more out of the way than the ones in St. Augustine. Lots more room in Jaxville, though. It just looks a bit rougher. Pricewise, you might find Jax yards a bit less expensive. What kind of work do you need done on your props? If Propspeed, don't trust any of the yards to be knowledgeable without specific instructions downloaded from the Propspeed web site.
Sorry I couldn't be more helpful, but we always used Lamb's Yacht Center in Ortega, and sailboats can't get there.
Just wanted to say 'Hi'. Where are you headed this winter? Back to the Keys?
