Pre-Purchase Survey
This is the most comprehensive type of survey and is strongly advised when purchasing either a new or used vessel.  Condition and overall operation of the vessel should be examined.  This covers structural integrity, electrical systems, the propulsion system, the fuel system, other machinery, navigation equipment, miscellaneous on-board systems, cosmetic appearance, electronics, and overall maintenance, as well as, an out of water inspection and a sea trial.

Insurance Survey
This inspection is performed so that the insurance company can determine whether or not the vessel is an acceptable risk.  They are interested in the structural integrity and safety for the vessels intended use.  Most insurance companies require a survey on older boats.  They will also want to know the vessel’s fair market value.

Appraisal Survey
This inspection is performed to gather enough information to justify or determine the fair market value of the vessel.  This is normally needed for financing, estate settlements, donations, and legal cases.

Damage Survey
This is performed to assess the extent of damage, recommend repairs, estimate repair cost, and if requested, possible cause.
