In October last year I bought my first boat. I had a survey carried out with the boat removed from the water and according to the report all was well. The boat was removed from the water for winter storage 2 weeks after the survey. I am now renewing the anti fouling and have noticed a fairly large patch of blister in an area of about 2 sq ft.(osmosis ?) I contacted the surveyor to ask if ,as he had missed this problem ,he had any insurance to cover the cost of repair. He told me that marine surveyors do not offer this kind of cover (as building surveyors do). Is this true ?
