2020 Jeanneau Sun Odyssey 389, Alameda, CA 94501

Identified risks (7)

Discrete events, kept out of the cost ranges so they stay visible and can be retired once you have looked.

• Original SD25 rubber diaphragm reaches scheduled replacement age before departure

  $4k–$8k

  50% likelyexpected $3kinferred

  Reasoning, not a source: Conditional, not a finding: the listed 2020 SD25 would reach seven years in 2027 if its diaphragm is original; no invoice is supplied, and manual revisions conflict on the exact interval, so the serial-specific schedule must be confirmed.

• Fitted passage sails fail sailmaker cloth, seam or shape assessment

  $7k–$16k

  25% likelyexpected $3kinferred

  Reasoning, not a source: Conditional, not a defect finding: sail dates and maker are not supplied; the boat carries an in-mast main, furling jib, storm jib, trysail and working jib, but listing appearance cannot establish remaining offshore life.

  Current listing“in mast furling”

• Rig, terminals or uninvoiced load-path structure fail specialist inspection

  $9k–$18k

  15% likelyexpected $2kinferred

  Reasoning, not a source: Conditional, not a finding: model-year wire is 1x19 stainless, but the listing supplies no rig invoice or inspection; the boat is only six years old, which keeps probability below older fleet candidates.

• Autopilot drive, bracket, wiring or commissioning needs localized remediation

  $500–$6k

  15% likelyexpected $375inferred

  Reasoning, not a source: The listing identifies p70s and ACU-400 but not the drive, EV-1 sensor, rudder reference or mounting; an installed system is positive evidence, while exact adequacy remains unresolved.

  Current listing“ACU400”

  Raymarine EV-400 Sail Pilot“Type 2 or Type 3”

• Localized moisture or delamination around fittings, hatches or long acrylic windows

  $2k–$18k

  10% likelyexpected $600inferred

  Reasoning, not a source: Model-level survey target only: the 2020 inventory specifies discontinuous balsa-cored injected deck construction and multiple flush hatches/windows; there is no hull-specific leak or moisture finding.

• Antifouling requires renewal before March 2028

  $3k–$5k

  75% likelyexpected $3kinferred

  Reasoning, not a source: Conditional planning risk: the seller reports bottom paint in 2024, which will be about four years old at departure; coating brand, application system, diver history and present condition are not supplied.

  Current listing“2024”

• Eight-person liferaft needs economic recertification before departure

  $800–$2k

  70% likelyexpected $980inferred

  Reasoning, not a source: The listing proves an eight-person valise raft exists but gives no make, offshore standard, manufacture date or certificate; service may restore it, while an uneconomic raft would leave the generic replacement line standing.

Systems to check (24)

• Standing rigginglisting only

  The 2020 factory inventory specifies discontinuous 1x19 stainless standing rigging and a deck-stepped double-spreader furling mast option. No hull-specific rigging invoice, inspection, damage history or present-condition evidence is supplied; age alone does not establish replacement need.

• Mast, boom and fittingslisting only

  This hull is listed with an aluminium in-mast-furling mast, rigid vang, bowsprit and spinnaker fittings. Mast, boom, gooseneck, spreaders, mast step, sheaves and furler internals have no documented inspection or service history.

• Running rigginglisting only

  Factory sail controls are led aft with cockpit-adjustable genoa cars and an additional roof winch; the current listing does not state line ages, chafe, spare halyards or preventers. Silence is uncertainty, not a replacement finding.

• Sailslisting only

  The listing states an in-mast furling main, furling jib, storm jib, trysail and working jib, with Code 0 readiness. Sailmaker, build dates, dimensions, cloth, seam condition and offshore remaining life are unverified.

  Current listing“storm jib”

• Enginelisting only

  Seller reports a 2020 Yanmar 3YM30AE, 29hp, with 835 hours. Yanmar specifies a naturally aspirated three-cylinder 1.266L engine and 125A alternator; service log, current plate, cold start, loaded RPM, fluids, exhaust elbow, cooling and blow-by are not documented.

  Current listing“835”

  Yanmar 3YM30AE“12V - 125A”

• Shaft, coupling, prop, stern glandlisting only

  The exact listed drive is a Yanmar SD25 saildrive, and the seller says the propeller is new without identifying make, type, pitch, invoice date or whether shaft seals/anodes were serviced. Diaphragm age, oil condition, corrosion, fishing-line damage and leak-alarm operation remain unknown.

  Current listing“SD25”

  Current listing“new propellor”

• Fuel tanks and systemlisting only

  Model and listing capacity is 34gal. The factory inventory specifies a fuel/water separator, but tank material, contamination, polishing history, hoses, shutoff access and sender accuracy are not documented on this hull.

• Electrical, AC and DClisting only

  The boat has factory 12V/110V distribution, shore charging, a 125A alternator, battery shunt and Bluetooth voltage/current display. No solar, inverter, MPPT, DC-DC charger, conductor/fuse topology or high-current inspection is evidenced. The shunt alone does not satisfy the bundled monitor/busbar/Class-T catalogue line.

  Sun Odyssey 389 2020 inventory“125 A”

• Battery banklisting only

  Seller reports three brand-new AGM house batteries plus a start battery; brand, Ah rating, invoice date, chemistry-specific charger settings and test results are absent. AGM is not treated as equivalent capacity credit against the central 600Ah LiFePO4 target.

  Current listing“AGM”

• Steering gearlisting only

  Deep-keel version is seller-described as single-rudder with twin wheels. The factory inventory says an emergency tiller was delivered, but its continued presence, steering cable/chain condition, quadrant attachment and autopilot tiller-arm arrangement are not evidenced on this hull.

  Sun Odyssey 389 2020 inventory“Emergency tiller”

• Autopilot and self-steeringlisting only

  Listing identifies Raymarine p70s, ACU-400 and a gyrocompass, establishing a substantial installed system. Raymarine's EV-400 architecture normally includes EV-1, rudder reference and a Type 2/3 drive, but the fitted drive and sensors are not named; serial check is required because only defined 2022 ACU-400 ranges are recalled.

• Hull and laminatelisting only

  Model-year construction is a solid hand-laid fibreglass hull with barrier coat. Seller calls the boat exceptional and reports 2024 bottom paint, but no survey, grounding/collision/claim history, moisture readings, laminate inspection or bottom invoice is supplied.

• Keel and keel boltslisting only

  Listing twice identifies the deep/standard L-shaped cast-iron keel at 6ft 5in, and official 2020 inventory gives 1.98m. This is exactly the 6.5ft gate after conversion/rounding, so keel identity, attachment, grounding evidence and actual loaded draft require physical confirmation before commitment.

  Current listing“deep (6'5") keel”

• Rudder and bearingslisting only

  Seller identifies the single-rudder deep-keel version; official model inventory specifies a GRP balanced rudder with stainless shaft. Bearings, stock, quadrant, moisture, impact history and emergency-steering demonstration are unverified.

• Deck, hardware and hull–deck jointlisting only

  Factory deck is injected GRP with discontinuous balsa core. Listing identifies midship cleats, teak trim, bowsprit, anchor roller and lifeline gates; present backing, sealant, moisture and stanchion/cleat loading are unknown.

  Sun Odyssey 389 2020 inventory“double level”

• Through-hulls and seacocksnot looked at

  No through-hull inventory, material, service record or exercise test is supplied. Silence does not establish a defect; surveyor must map and operate every seacock and inspect hoses, clamps and bonding as applicable.

• Plumbing, water tanks and headslisting only

  Listing gives the standard 53gal fresh-water tank plus a 34gal optional tank, for 87gal total if both are connected and sound; it also lists one head and cockpit shower. Factory system includes a 21gal holding tank, manual cockpit bilge pump and electric pump, but catalogue-required second manual pump below is not evidenced.

  Current listing“Additional water tank: 34 gal”

  Sun Odyssey 389 2020 inventory“Manual bilge pump”

• Ground tackle and windlasslisting only

  Installed equipment is a 44lb Delta primary, an unidentified spare anchor, 150ft of 3/8in chain plus rope, and electric windlass. Chain is only partial capacity credit; the Delta is not assumed equivalent to the central 55lb Rocna target, and gypsy/chain compatibility and loaded operation remain unverified.

  Current listing“150'”

  Current listing“windlass”

• Safety equipmentlisting only

  An eight-person valise liferaft and EPIRB are listed, and the factory stern-pulpit emergency ladder plus swim-platform ladder may aid recovery. Certification, registration, expiry, self-deployability and the rest of the offshore safety inventory are unknown; generic catalogue lines remain unless specifically credited.

  Current listing“EPRB”

• Electronics and navigationlisting only

  Strong installed Raymarine package: i70s wind/depth/speed, Ray53 fixed VHF, AIS700 5W SOTDMA transceiver, p70s/ACU-400 pilot, Axiom Pro 9, Navionics and mast-mounted radar. Exact radar model, handheld VHF, software levels, network topology and loaded operation are unresolved; AIS, plotter and instruments receive full functional credit.

  Current listing“radar”

  Raymarine AIS700“5 W SOTDMA”

• Canvas, dodger and coverslisting only

  Dodger/sprayhood, wheel/table covers and cockpit cushions are listed. No bimini or foredeck awning is evidenced, and canvas age, stitching, window clarity and waterproofing are not documented.

• Windows, hatches and portslisting only

  Factory arrangement includes four opening deck hatches, long acrylic deck windows and multiple ports; listing includes shades and screens. No leaks are disclosed, but seal, crazing and adjacent core condition require hose and moisture testing.

• Dinghy and outboardnot looked at

  No dinghy, outboard or foredeck stowage arrangement is evidenced in the listing. This is not a hull-specific cost because the central catalogue already carries those functions; ask whether any unlisted equipment is included before leaving the lines standing.

• Interior and sea berthslisting only

  Three-cabin/one-head layout has deluxe mattresses, white leatherette saloon cushions, convertible table, diesel heat, 12V refrigerator, two-burner stove and microwave. It provides excellent harbour comfort but pushes double berths into the ends and no dedicated offshore lee-clothed sea berth is evidenced. inferred
