how to buy it now

From our fabulous forums…
Got a great price on a boat. I want a survey before I write a check. Seller wants me to have insurance before I move boat to get it hauled for a survey. So far no one will write policy without survey. Seller is very busy professional and we can’t get on boat at same time to get it moved.
Boat is at Grass Island which does not have hauling facility. Any ideas? Thanks in advance for the inevitable helpful and not so helpful responses.
