He may be talking about a program similar to the one they have at Virgin Gorda Yacht Harbour in the BVI. They store your boat in the yard, and put it in a slip for you when you tell them you're coming to sail. You get a fixed number of dry-to-wet and back cycles for a fixed price
, if I remember correctly. Cheaper than renting
a slip, and a discount on the haul/launch price
, and the boat is ready to sail when you get there.
