A quick google revealed a established marine surveyors firm out of northern California. Mr Wedlock's resume shows him being a member of the Society of naval Architects and Marine Engineers and a member of the National Association of Marine Surveyors plus being the holder of a 300 ton Masters License for power and sail. You provide no information about the scope and purpose of the survey nor about the condition of the boat. The fact that the boat may be 30 years old can be irrevelant. Don't know this firm nor their reputation but would recommend that if you have a question about the work performed that you contact them.
