A vessel condition and valuation survey documents the structural integrity, system functionality, safety compliance, and market value of a yacht, powerboat, or sailboat. Below is the technical scope we follow, the standards that guide our findings, the tools we use, how valuation is determined in the Seattle–Tacoma market, and exactly what our final report contains.
Inspection Scope: Systems and Structures We Evaluate
Surveys are non-destructive, visual and functional inspections designed to reveal observable conditions at the time of inspection. When access permits, we inspect:
- Hull and deck: Laminates, cores where accessible, topsides, decks, transom, stringers, bulkheads, tabbing, through-hulls, seacocks, hull-to-deck joint, windows/ports, stanchion bases, deck hardware bedding.
- Propulsion and running gear: Engines (external inspection and running observations if operated), transmissions, shafting, stuffing boxes/shaft seals, struts, propellers, rudders, steering systems, trim tabs, thrusters, engine mounts and alignment indicators.
- Electrical systems: AC/DC distribution panels, overcurrent protection, wiring practices, batteries, chargers/inverters, bonding/grounding, shore power inlets, GFCI/AFCI devices, installation quality and labeling.
- Fuel and exhaust: Tanks, fills, vents, supply/return lines, filters, clamps, fire-resistance where applicable, exhaust risers, waterlocks, mufflers, and gas detection where fitted.
- Plumbing: Potable water tanks and pumps, hot water heaters, hoses and clamps, sanitation systems (toilets, holding tanks, venting, Y-valves), bilge pumps and alarms.
- Safety gear: Basic carriage and installation checks for PFDs, fire extinguishers, fixed fire systems (if present), visual distress signals, sound devices, carbon monoxide detection, navigation lights.
- Electronics and navigation: Installation quality, power and data cabling practices, sensor mounting, and basic power-on/function checks (e.g., GPS, depth, VHF, radar, autopilot) when systems are energized.
Additional sailboat items include visible standing/running rigging, chainplates, mast step/partners, and deck compression indicators from accessible locations.
Standards and Professional References
Findings and recommendations are referenced to widely recognized marine guidelines and good marine practice, including:
- ABYC (American Boat & Yacht Council) standards, such as E-11 for AC/DC electrical systems and applicable fuel and ventilation standards.
- NFPA 302 (Fire Protection Standard for Pleasure and Commercial Motor Craft).
- U.S. Coast Guard carriage and lighting requirements (as applicable for safety observations).
- SAMS (Society of Accredited Marine Surveyors) Recommended Survey Report Content and Code of Ethics, guiding impartiality, clarity, and disclosure of limitations.
Where a specific published standard does not directly apply, we reference accepted industry practice for comparable vessels and installations.
Tools and Methods Used
We use appropriate, non-destructive tools to assess condition:
- Moisture meter and percussion sounding on fiberglass/wood laminates to help identify elevated moisture or voids (interpretation considers temperature, coatings, and construction).
- Thermal imaging when conditions allow, to screen for moisture anomalies, overheating connections, or insulation voids.
- Digital multimeter for basic electrical diagnostics; clamp meter for current checks; IR thermometer for running temperature observations.
- Borescope for limited access spaces where openings exist.
- Thickness gauging (if suitable access and material) to screen metal plating where appropriate.
Sea trial observations, if performed, are used to verify operating parameters such as engine performance under load, steering, handling, vibration, and basic electronics operation. Out-of-water inspection enables a closer look at below-waterline structures and running gear.
What Is and Is Not Included
- Included: Visual and functional checks of accessible areas and systems; condition grading; safety and standards observations; non-destructive measurements; review of visible HIN/registration plates and nameboards; verification of installed equipment observed.
- Not included: Destructive testing; removal of permanently fastened panels or headliners; internal engine or generator teardown; software updates or full diagnostics of electronics; pressure testing of tanks; certified load testing of rigging or hardware.
- Cosmetic vs. structural: We note cosmetic issues when they hint at deeper problems (e.g., gelcoat cracking at hardware), but the report emphasizes structural integrity, safety, and function.
- Access limitations: Locked, stowed, or inaccessible spaces are excluded. Findings reflect conditions on the day of inspection and may be affected by cleanliness, temperature, recent rain, and power availability.
Valuation Methodology and Seattle–Tacoma Market Context
The report provides an opinion of Fair Market Value (FMV) and, when appropriate, Replacement Cost New Less Depreciation (RCNLD). Our valuation approach includes:
- Comparable sales: Analysis of recent sales and asking data of similar make, model, year, and configuration, with emphasis on Pacific Northwest results when available.
- Condition adjustments: Adjusting for hull/deck condition, machinery hours and maintenance, electronics suite, recent refits, canvas/rigging age, and documented upgrades.
- Market context: Local factors such as the region’s wet climate (moisture intrusion and corrosion risks), demand patterns in Seattle–Tacoma, seasonal listing activity, and moorage dynamics that can influence buyer behavior.
We explain valuation rationale in plain language and reference the key comparables and adjustment factors applied.
How Scope Varies by Vessel Type and Age
- Sailboats: Added attention to chainplates, mast step, keel-to-hull joint, deck compression, and standing/running rigging observed from the deck and accessible lockers. Aloft or dye penetrant testing of hardware is outside standard scope.
- Powerboats: Emphasis on propulsion, exhaust, cooling, fuel system installation, and vibration/handling under way. High-performance installations prompt closer review of mounts and ventilation.
- Yachts with complex systems: Broader review of generators, inverter/charger systems, hydraulic platforms, stabilization, and integrated electronics installation quality.
- Older vessels: Expanded attention to moisture in cored structures, corrosion, bonding, tank integrity, and legacy wiring. Wood construction may receive more percussion sounding and fastener sampling observations where visible.
Sample Report Deliverables
- Narrative findings: System-by-system observations, photos, and standards references where applicable.
- Recommendations with priority levels: Commonly organized as Safety/Standards (address promptly), Functional/Preventive (near-term), and Cosmetic/Deferred (owner preference).
- Valuation summary: FMV and, where relevant, RCNLD, with a brief explanation of comparables and adjustments.
- Photo documentation: Clear images of HIN, machinery plates, key findings, and representative system installations.
- Sea trial and haul-out notes: If these steps are completed during the survey, we include performance metrics and below-waterline observations.
- Scope and limitations statement: Defines methods used, access constraints, and any assumptions necessary to interpret results.
Risk Management and Next Steps
Survey results often identify items that merit further specialist evaluation (e.g., engine diagnostics by a mechanic, rigging inspection by a rigger, or corrosion analysis on metal hulls). We clearly flag those items so buyers and brokers can make informed decisions based on priority and cost-to-remedy considerations.
Frequently Asked Questions
Do you perform destructive testing if a hidden issue is suspected?
No. A vessel condition and valuation survey is non-destructive. If hidden damage is suspected, we recommend targeted follow-up by the appropriate specialist (e.g., core sampling by a boatyard or advanced engine diagnostics by a mechanic).
How are electronics evaluated during the survey?
We check installation quality, wiring practices, and basic power-on functionality when systems are energized. We do not perform software updates, network reconfiguration, or bench-level diagnostics of individual components.
Are below-waterline components fully inspected without a haul-out?
Inspection of running gear, through-hulls, and bottom condition is best accomplished out of the water. Without a haul-out, assessment is limited to what can be seen from the dock or during operation and may not reveal coating, fastener, or bearing issues.
Will you climb the mast on a sailboat?
Standard scope includes rigging observations from the deck and accessible areas. Aloft inspection is not part of a standard survey; if needed, a qualified rigger can perform it using appropriate equipment and procedures.
A buyer considering a fiberglass sailboat uses the survey to confirm hull dryness around the chainplates, verify sanitation system compliance, and understand the cost-to-correct for dated standing rigging. The valuation section references recent Pacific Northwest transactions, clarifying how condition and upgrades affect price expectations.
A broker listing a motoryacht requests a condition and valuation survey to document system functionality and create a prioritized list of recommendations. The report’s photo set and standards-cited notes help the seller address safety items before showings and support realistic pricing aligned with Seattle–Tacoma market trends.
