How to Choose a Marine Surveyor?
Choose a marine surveyor by verifying credentials with recognized industry bodies (such as the International Institute of Marine Surveying (IIMS), ABYC, or SAMS/NAMS), confirming independent insurance/lender acceptance, reviewing sample reports, and selecting a professional with direct expertise in your vessel’s specific hull type and systems.

What is done in a marine survey?
A comprehensive marine survey involves a detailed inspection of a vessel’s hull integrity, structural condition, propulsion, electrical systems, safety gear, and underwater running gear during a haul-out. The surveyor conducts non-destructive testing—such as moisture metering and percussion sounding—to identify hidden defects, resulting in an objective valuation and safety report.
How to prepare your boat for a marine survey?
Properly preparing your boat ensures an efficient inspection and prevents uninspected areas in your final report. Essential steps include clearing access to lockers and bilges, organizing vessel documents and certificates, ensuring charged batteries and commissioned systems, and coordinating haul-out logistics and bottom pressure washing with the shipyard.
How much does a marine survey cost?
Marine survey fees are typically calculated on a per-foot or per-meter basis, varying according to the vessel’s size, age, hull complexity, and location. In addition to the surveyor’s professional fee, buyers and owners should budget for shipyard haul-out charges, pressure washing, and optional engine diagnostics.
What are the different types of marine surveys?
Marine surveys are tailored to specific objectives, including comprehensive pre-purchase inspections, risk-focused insurance condition assessments, financial market appraisals, and post-incident damage surveys. Choosing the right survey type ensures vessel owners, buyers, and underwriters receive the precise technical evaluation they need for their situation.
How often should a boat be surveyed?
Marine insurance companies typically require a comprehensive condition and valuation survey every 3 to 5 years, with stricter schedules for vessels over 10 to 15 years old. In addition to policy renewals, periodic surveys ensure ongoing seaworthiness and are required for commercial coding compliance.

What happens after a marine survey?
What happens after a marine survey?
Following the physical inspection and sea trial, a formal marine survey report is typically delivered within 2 to 5 business days, detailing full system evaluations and prioritized defect recommendations. Buyers use these findings and classified defect reports to negotiate necessary repairs, escrow allowances, or purchase price adjustments prior to closing.

How long does a marine survey take?
On-site marine surveys typically take 3 to 8 hours depending on vessel length, age, and system complexity. Haul-out hull inspections and underway sea trials generally add 1 to 2 hours each, with written reports delivered electronically within 2 to 5 business days following the physical inspection.

What are the limitations of a marine survey?
A marine survey is a visual, non-destructive inspection confined strictly to accessible areas. It does not involve dismantling cabinetry, unfastening structural components, or internal engine teardowns, and it defines clear operational boundaries where secondary specialist checks may be recommended.
What is included in a sea trial?
An underway sea trial evaluates engine performance under actual load, Wide Open Throttle (WOT) parameters, thermal limits, steering responsiveness, trim tab operations, shaft/hull vibrations, and navigation electronics under active sea conditions.

What documents are needed for a marine survey?
Key documents include vessel registration or title, HIN verification, Bill of Sale, engine service logs, prior survey reports, electrical schematics, and safety equipment inspection certificates.
