If you’ve owned a boat for any length of time, you probably know that insurance companies hire independent marine surveyors to conduct insurance surveys on the boats that they insure.

Joe is the guy who knows how to wire a house and thinks that boats are no different. The house business isn’t so good, so he switched to boats.
