Most insurance companies require the owner to commission a survey prior to renewing a policy once a vessel is 20 years old, and then at five yearly intervals.
The purpose of the insurance survey is to identify any defects in the vessel that would represent an unacceptable risk to underwriters. Such defects could be found in the structure and structural attachments, ballast, steering system, gas system, electrical systems, sails and rig, deck fittings, ground tackle, windows and hatches, through hull fittings and their hose attachments, propulsion equipment and engines, safety equipment, tank and fuel installations, bilge systems and navigation equipment.
Most insurance companies will accept notification from the Owner when the required recommendations have been carried out, so a follow up inspection is rarely required.
