We once chartered a PC in the PNW from Anacortes Yacht Charters. One nice things they provided was the yacht owners comments. The owner had spent some time going over all of the little details of the yacht systems. I spent some time before our charter studying the information provided and felt very comfortable with the boat once we were aboard. Since the owner had taken the time to explain all of the systems aboard I felt obligated to read and learn the information. Any quirks and boat specific pieces were explained in detail. I think I was a more informed charterer and knew how to take better care of the boat because of this. I've never been so well informed about a boat before we boarded with any other charter outfit and I've wished all would provide owner specific knowledge; it helps!
