I had a monohull surveyed in San Diego 3 years ago by a man named "Bunker Hill" He did an excellent job and was very reasonable. He's located in Newport Beach. I think this number might still be valid.
Doug Wright was the surveyor we went with. He was very knowledgeable and down to earth. He will remove your rose colored glasses and shoot you straight on the condition of your prospective boatpurchase.
I highly recommend him and would hire again if I were to buy another boat!
