Use this Seattle-focused checklist to prepare your yacht, paperwork, and logistics for a smooth, accurate yacht condition and value survey. These steps help buyers, sellers, and brokers avoid delays, ensure full system access, and reflect the realities of Puget Sound marinas, yards, and weather.
Document Readiness: What to Provide Up Front
Having clear documentation lets the surveyor verify details and evaluate condition and value accurately.
- Registration and title (or documented vessel paperwork) and any tender titles.
- Maintenance records: engine services, oil analyses, rig inspections, battery replacements, and any warranty work.
- Upgrades and modifications: dates, installer information, manuals, and part/model numbers (electronics, chargers, inverters, heaters, windlasses, thrusters, rigging, sails).
- Recent yard invoices: bottom paint, blister repair, shaft/prop work, through-hull replacements, zincs, anodes, cutless bearings, keel or rudder work.
- Equipment list: include safety gear (PFDs, flares with expiry dates, extinguishers with service tags), electronics, ground tackle, canvas, spares, and loose gear that conveys.
- Logbook notes on incidents (groundings, lightning, collisions) and remedial repairs.
Vessel Access and Utilities: No Surprises on Arrival
Ensure the yacht is accessible and energized so systems can be tested efficiently.
- Keys and codes: dock gate, dock box, cabin, engine room, and any lockouts for batteries or fuel.
- Batteries: fully charged; leave chargers/inverters on and accessible. Label battery switches.
- Fuel levels: maintain a safe, operational level for starting and sea trialing; avoid running near empty.
- Shore power: confirm cord compatibility and pedestal availability; test GFCI/ELCI breakers beforehand.
- Water systems: if winterized, notify the surveyor in advance. Be prepared to de-winterize potable water and raw-water systems (or note what cannot be commissioned).
- LPG/CNG and diesel heaters: provide access to tanks/lockers and ensure ventilation.
Systems Readiness and Safety Compliance
Functional checks depend on access and baseline serviceability. Align safety gear with ABYC and USCG norms.
- Engines and generator: cold-start ready with accessible dipsticks, strainers, seacocks, and exhaust risers. Have keys, start sequences, and any special procedures available.
- Electronics: power up MFDs, radar, AIS, VHF (verify MMSI), depth/speed, autopilot. Provide passwords if applicable.
- Electrical: label main breakers; expose service panels if safe. Note any known inoperable circuits.
- Fuel and lube: make engine room clean, with absorbent pads in place; remove excess rags or hazards.
- Safety gear: verify extinguisher service dates, visual distress signals’ expiry, sound signaling device, navigation lights, horn, placards, and appropriate PFD count and types.
- Rigging/sails (sailboats): have winch handles aboard, halyards led, sails accessible for inspection if agreed.
Decluttering and Safe Access Throughout
Clear access speeds the inspection and reduces missed items.
- Bilges and sumps: remove stored items; ensure limber holes and pumps are visible and testable.
- Lockers and lazarettes: move personal items so tanks, bonding wires, steering gear, and through-hulls are accessible.
- Engine space: remove non-essential stowage; allow 360° access where possible.
- Cabin spaces: stow loose gear; secure breakables ahead of sea trial.
Sea Trial Preparation for Puget Sound Conditions
Coordinate a safe, efficient underway session that reflects normal operations while respecting local traffic and weather.
- Crew availability: ensure a qualified operator is present to run the vessel; align on roles for docking, fendering, and lookout.
- Fuel planning: carry sufficient fuel for warm-up, varied RPM runs, and return with reserve; confirm tank selection procedures.
- Lines and fenders: have extras ready for transits and busy marina approaches.
- Weather and tides: check local forecasts, currents, and ferry routes; adjust timing for safe testing and visibility.
- Test plan: discuss ahead—steering, throttle response, RPM sweep, autopilot, trim tabs, windlass, and emergency stops where safe.
Haul-Out Prep at Seattle-Area Yards
Coordinate with a local yard in advance; many require reservations and proof of authorization.
- Booking: confirm date/time, LOA/beam/draft, and special handling notes with the yard.
- Sling marks: identify or estimate lift points; clear bottom growth near marks if possible.
- Lockable storage: secure valuables; some yards have open staging areas.
- Environmental rules: expect restrictions on scraping, sanding, and washdowns; follow yard policies for bilge water and paint dust containment.
- Running gear access: remove shaft locks or line cutters’ covers if present and safe; bring any proprietary prop puller info if relevant.
Moisture and Corrosion Considerations in Puget Sound
Local waters and climate can mask or exaggerate readings; simple steps can improve clarity.
- Drying time: if possible, ventilate cabins and lockers 24–48 hours before the survey to reduce interior humidity that can affect moisture meter readings.
- Dehumidifiers and heat: running a small dehumidifier or cabin heat (safely) can stabilize conditions and improve inspection visibility.
- Zincs and bonding: visually check anodes for depletion; confirm bonding wire terminations are clean and accessible for inspection.
- Shore power corrosion paths: ensure galvanic isolator or isolation transformer information is available; note any stray-current issues you’ve observed.
Buyer and Seller Roles, Presence, and Next Steps
Clear expectations help the day go smoothly and keep findings in context.
- Presence: it’s helpful for buyers and sellers (or representatives) to be available in person or by phone for access questions and operational nuances.
- Boundaries: avoid crowding the surveyor during tests; save non-urgent questions for natural breaks.
- Decisions on the day: plan who authorizes sea trial departure, yard charges, or minor commissioning steps (e.g., opening a winterized system) if needed.
- After the survey: expect a written report with observations and recommendations; coordinate with your broker on follow-ups, specialist evaluations, or re-inspection if requested.
Frequently Asked Questions
Do we need shore power connected for the survey?
Yes, if available. Shore power lets the surveyor verify charging systems, AC circuits, and onboard equipment under normal conditions. If shore power is not available, advise in advance so battery capacity and test scope can be planned accordingly.
What if parts of the boat are winterized?
Tell the surveyor ahead of time. Some systems can remain winterized, but it limits functional testing. If you want a full evaluation, plan to safely de-winterize potable water, raw-water intakes for generators or air conditioning, and any heaters you want tested.
How much fuel should we carry for the sea trial?
Carry enough to run normal warm-up and RPM tests with a safe reserve for return, considering currents. Avoid near-empty tanks, which can stir sediment and interrupt testing. If multiple tanks exist, know the selection procedures.
What documents help most if I don’t have a complete service history?
Provide what you can: recent yard invoices, parts receipts, survey reports from prior years, and manuals for installed equipment. A current equipment list and any notes on upgrades or known issues are especially helpful for context.
A Seattle buyer schedules a Saturday survey with haul-out in Tacoma. The seller shares maintenance logs, an equipment list, and confirms shore power the night before. On the day, the batteries are topped up, lockers are cleared, and the yard has sling points noted. The sea trial proceeds efficiently, including an RPM sweep and autopilot check, and the report arrives with clear recommendations.
A seller preparing a sailboat in winter runs a dehumidifier for two days, de-winterizes the freshwater system, lays out rig inspection records, and verifies safety gear dates. With bilges and chain locker cleared, the surveyor gains easy access, moisture readings are more meaningful, and the afternoon sea trial avoids ferry traffic windows.
