A Pre‑Purchase Marine Survey is a critical due diligence step designed to thoroughly assess a vessel’s condition before finalizing a purchase.
1. Comprehensive In‑Water Inspection
Everything visible—deck, cabin, electronics, plumbing, wiring, and mechanical systems—is examined. Report notes “serviceable” vs. faulty components, and highlights any immediate safety issues or deferred maintenance needed
2. Haul‑Out & Underbody Check
The boat is lifted for a close inspection of the hull’s outer surfaces, keel, propeller, shaft, rudder, cutlass bearing, and through-hull fittings for corrosion or damage .
3. Moisture & Structural Testing
Tools like moisture meters and phenolic hammers detect water intrusion or blistering in fiberglass, wood, or composite structures—key indicators of core or laminate issues .
4. Sea Trial Performance Check
During a sea trial, engine performance and handling systems—steering, controls, engine mounts, exhaust—are tested under load. Sailboats also undergo rigging inspection from deck level .
5. Mechanical & Specialist Recommendations
Surveyors perform visual checks on engines and systems. While not a deep mechanical overhaul, they may recommend a focused engine or rig survey for deeper technical issues .
6. Report & Valuation
You're presented with a detailed report that grades issues (Immediate, Near-Term, Recommended) and provides a fair‑market value estimate based on comparable vessels .
An Insurance Marine Survey is a specialized inspection typically required by insurers to assess the condition, value, and safety of a vessel before issuing or renewing coverage. Unlike a pre-purchase survey, which is buyer-focused, an insurance survey is tailored to underwriting risk and compliance.
1. Hull, fittings & equipment: Evaluation includes structural integrity, thru-hulls, deck hardware, rigging, and safety gear
2. Mechanical & propulsion systems:
Engines, fuel, exhaust, and drive systems are examined for wear, leaks, and compliance .
3. Electrical, navigation & safety systems:
Wiring, navigation electronics, bilge pumps, lightning protection, and firefighting equipment are evaluated to ensure functionality and ABYC or NFPA compliance
Note: Insurance surveys do not include sea-trials and will not provide information on cosmetic deficienies nor function of the vessel's electronics or water systems
An Appraisal Marine Survey is conducted specifically to determine a vessel’s fair market value, combining assessment of its condition and valuation. It differs from a general condition survey by focusing primarily on value estimation for legal, financial, or administrative purposes.
1. Condition Assessment:
A thorough—but often cursory—inspection of the hull, decks, superstructure, machinery, onboard systems (electrical, plumbing, safety equipment), and navigational gear. The goal isn’t in-depth troubleshooting, but sufficient review to support a credible valuation.
2. Valuation Analysis:
The fair market value is determined using factors such as the vessel’s age, make, model, condition, equipment, and current market demand. Comparisons with recent sales and replacement-cost estimates are typically used .
3. Report Preparation:
The result is a clear, concise document that outlines the vessel’s basic specifications, general condition, and established fair market value. It may include photos and commentary but does not delve into extensive structural or mechanical detail
