We used to moor the boat at Newport Shores and we figured 3 hours from/to the Locks. Make sure you have the necessary equipment for the locks: fenders for both sides, 50' mooring lines (IIRC). I would strongly urge you to not try to go through the locks by yourself in a new (to you) boat unless you have a lot of experience locking through (doesn't sound like it). The bridges respond to horn signals or on Ch. 13 (low power). Good luck, have fun with the new boat.
