• Wet or compressed balsa core around deck fittings and hatches

  $3k–$25k

  35% likelyexpected $3kinferred

  Reasoning, not a source: The deck is balsa-cored and 28 years old, while no moisture survey or rebedding history is supplied.

  Practical Sailor Construction Review“End-grain balsa forms the core”

• Grounding damage or loss of structural-grid bond near the keel

  $3k–$40k

  15% likelyexpected $2kinferred

  Reasoning, not a source: The hull relies on a bonded full-length structural grid and external iron keel; grounding history and prior surveys are omitted.

  Practical Sailor Grid Description“full-length fiberglass grid structure”

• Claimed engine hours are incomplete or long idle periods caused internal deterioration

  $5k–$22k

  20% likelyexpected $2kinferred

  Reasoning, not a source: Seven hundred sixty hours over roughly 28 years is only about 27 hours annually; meter replacement and storage history are not addressed.

• Original chainplates or molded-in tie-downs remain uninspected despite new wire

  $2k–$15k

  20% likelyexpected $1kinferred

  Reasoning, not a source: The listing describes new standing-rigging elements but no chainplate or internal tie-down removal and inspection.

  Beneteau Equipment List“chromium-plated bronze shroud chainplates”

• Aged portlight and hatch seals leak into the interior or deck core

  $2k–$15k

  50% likelyexpected $3kinferred

  Reasoning, not a source: The model has numerous Lewmar hatches and opening ports; a 1998 owner report describes window and port seals as worn after 28 years.

  Oceanis 36 CC Owner Report“seals on the windows...were worn”

• Steering play from upper bearing plate, rudder bearing or linkage wear

  $1k–$10k

  35% likelyexpected $2kinferred

  Reasoning, not a source: Practical Sailor reports owner complaints about steering play and a bearing-plate remedy on this model.

  Practical Sailor Rudder Review“owners complain about play”

• Large freshwater tanks or inaccessible fittings leak

  $2k–$15k

  20% likelyexpected $1kinferred

  Reasoning, not a source: The model carries roughly 420L in two tanks and no tank, hose or pressure-test history is supplied.

  Manufacturer Brochure“Capacité eau 420 l. env.”

• The advertised new main furler does not include the aging mast extrusion or all internal wear components

  $2k–$9k

  20% likelyexpected $900inferred

  Reasoning, not a source: The phrase 'new main furler' is ambiguous and could mean anything from line/drum components to a complete replacement system.

• Iron-keel corrosion returns beneath the 2023 epoxy treatment

  $800–$7k

  40% likelyexpected $1kinferred

  Reasoning, not a source: The seller already found rust requiring removal and epoxy treatment; iron keels commonly need recurring coating maintenance.

  Practical Sailor Keel Review“iron...requires an epoxy treatment”

Systems to check (24)

• Standing rigginglisting only

  Seller states Hansen Rigging replaced shrouds, backstays, headstay and spreader bushings in June 2025. Chainplates, tie-downs, mast step and terminal specifications are not described.

• Mast, boom and fittingslisting only

  Deck-stepped aluminum mast by model specification; seller states a new main furler in 2025. Scope, mast corrosion and boom/gooseneck condition are unknown. inferred

• Running rigginglisting only

  New halyards, topping lift and boom-vang line are listed, but the replacement was explicitly partial and remaining line ages are omitted.

• Sailslisting only

  In-mast main, furling genoa and spare jib are included. No sail ages, construction, UV-cover age or condition grades are supplied.

• Enginelisting only

  Yanmar 3GM30F with approximately 760 hours. The 27hp engine was a documented factory option, but service, mixing-elbow, injector, cooling and meter history are omitted.

• Shaft, coupling, prop, stern glandnot looked at

  Manufacturer equipment list specifies shaft drive and a fixed three-blade propeller. Shaft seal, cutless bearing, propeller, alignment and engine-mount condition on SEQUOIA are unknown. inferred

• Fuel tanks and systemnot looked at

  Model documents conflict between approximately 130L and 150L. SEQUOIA's tank material, actual capacity, inspection access, hose age and cleaning history are omitted. inferred

• Electrical, AC and DClisting only

  NOCO Genius 10x3 charger installed April 2025 and Garmin NMEA 2000 electronics in June 2024. Alternator output, shore-power protection, galvanic isolation, conductor condition and battery monitoring are omitted.

• Battery banklisting only

  One 125Ah Lifeline AGM start battery and two 198Ah West Marine AGM dual-purpose house batteries were installed July 2023. They do not satisfy the catalogue's 600Ah LiFePO4 requirement.

• Steering gearnot looked at

  Push-pull pedestal steering and emergency tiller were model equipment. SEQUOIA's wheel play, linkage, quadrant/bearing plate and actual emergency-tiller inventory are not documented. inferred

• Autopilot and self-steeringnot looked at

  No autopilot is mentioned. Treat the catalogue autopilot requirement as fully outstanding unless the seller supplies evidence. inferred

• Hull and laminatelisting only

  Solid fiberglass hull with bonded structural grid by manufacturer documentation. Seller states a July 2023 haul, sanding and two coats of Micron 66; no survey or grounding history is supplied. inferred

• Keel and keel boltslisting only

  Five-foot iron wing keel. Seller states rust was removed and the keel epoxy-treated in July 2023; keel bolts and seam condition are not described.

• Rudder and bearingsnot looked at

  Deep spade rudder with composite stock by model documentation. No bearing, steering-play, moisture or repair history is supplied. inferred

• Safety equipmentnot looked at

  No offshore safety inventory, liferaft, EPIRB, MOB electronics, jacklines or storm-management gear is mentioned. inferred

• Electronics and navigationlisting only

  Modern Garmin NMEA 2000 instruments are a positive, but the DST810 installation is incomplete. The 6-inch ECHOMAP is below the planned 9-inch offshore MFD, and radar, AIS and exact VHF model are not listed.

• Canvas, dodger and coversnot looked at

  No dodger, bimini, enclosure or awning age and condition is supplied despite the center-cockpit design's reliance on weather protection.
