The requirements for a pre-registration survey are dependent on age and condition of the vessel and initial contact to discuss whether a survey is required should be made to the Principal Surveyor at marine.survey@gov.im.The technical information required for vessels registering can be found in the pre-registration letter.

When a pre-registration survey is required a Senior Surveyor from the IOM Ship Registry will conduct the survey & inspection on the ships proposed for registry. Surveyors regularly travel to all major ports and generally an inspection can be arranged to suit a ship's schedule at any time provided the Ship Registry has enough notice.
