The marina, and the slip Baraka goes into is an unbelievable tight spot, it so amazes me , how they have been going in and out of this spot for 7 years now!!!     Vaughan has to slowly come by the end of the slip , then the first mate ( or captain) has to step off, onto the dock, holding a line, as Vaughan slowly keeps on bringing the boat forwards, then the idea is to pull the stern slowly into the slip, remember , this is a very heavy boat!!!    The bow thruster should make this easier, much easier, it will still take a lot of practice, but we could already see that it will be a great help.You can see here ,the bow thruster working, pushing the boat over.
