I am considering purchasing a 2002 Jeanneau 43 but the survey pointed out several areas in need of repair. There is a leak that has caused a fair amount of mold in the forward cabin and water under the mast that give me particular concern. The surveyor suggested not sailingh until the mast is checked out. My borker (a boat yard owner) has quoted repairs at $20,000 based on the survey - he has not seen the boat. This is my first boat. Is it normal to need so many repairs when you buy a boat and is it possible to quote repair work without seeing the boat?
