Financing Surveys are done specifically for the purpose of financing a boat.   Financing a boat is just as involved as financing a house.  A boat will qualify for a interest tax deduction just as your home (see your accountant for details).  Finance companies are mostly concerned with the condition and the value of the boat that you are purchasing.  

Finance companies will require a survey report sometimes the day after the survey is performed.  Their needs vary with the institutions and banks each finance company deals with.  Often a finance company will have several banks that will make loans and each may require a copy of the survey report.

Finance surveys are very comprehensive and generally consist of about 15 or more typewritten pages.
