What kind and size of boat? Mono or Cat? Draft? It makes a difference. I would be surprised if you couldn't get into AYH in Red Hook or Yacht Haven at almost any time. Crown Bay will usually have something. Compass and Independent are expanding right now so it's likely you could get in there as well. We don't have much space open in French Town, it would depend on the how many days and exact dates. What kind of work are you doing? That also would effect where you want to be. Proximity to parts and available trades if you need them.
