Avoid Boat-buying Scam--Escrow Service?

[Triton318]

I found what looks like might be a great deal on a sailboat, but am concerned it might be a scam. The owner purportedly lives in England, and the boat is located in the United States. Does anyone know if it's possible to use some type of escrow service for the purchase of a boat? I'm thinking in terms of--1. the seller sends the title to the boat to the service, 2. I send the money to the service, 3. the service verifies that the title is okay, 4. the service sends the money to the seller, and 5. the service sends me the title.
