2004 Beneteau Oceanis 423 "XALI", Brisbane Marina, Brisbane, California / San Francisco Bay

Identified risks (11)

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

• Hidden keel-sump or bonded-grid damage from a prior grounding

  $3k–$60k

  3% likelyexpected $540inferred

  Reasoning, not a source: The current owner reports no structural damage or hard grounding during eight years, and says the prior ten-year owner reported the same. The 2018 in-water survey found no apparent structural delamination, but it did not inspect underwater gear or perform destructive testing.

  Beneteau General Specifications“structural inner moulding is bonded”

• Wet or delaminated balsa deck around fittings, hatches or chainplates

  $2k–$40k

  18% likelyexpected $3kinferred

  Reasoning, not a source: The model uses a balsa-sandwich deck. The 2018 insurance survey reported no apparent delamination, and lenses were replaced that year, but it did not provide a moisture map; current minor portlight drips justify targeted testing without proving wet deck core.

  Beneteau General Specifications“deck is sandwich construction”

• Material engine or transmission work despite favorable recent cooling-system service

  $3k–$35k

  10% likelyexpected $1kinferred

  Reasoning, not a source: The D2-55 has 1,609 owner-confirmed hours and is reported operational with recent cooling/exhaust service. The 2018 survey described mounts and hoses favorably but had no engine specialist or sea trial; current loaded data and fluid analysis remain absent.

• Original chainplates, tie rods or mast-support structure were not included in the 2020 rerig

  $2k–$30k

  6% likelyexpected $600inferred

  Reasoning, not a source: The 2020 SF Boatworks invoice confirms complete standing-rigging removal/replacement, new headstay wire, mast unstep/restep and tuning. The owner reports the chainplates were verbally judged good, and the 2018 survey found them secure at eye level, but no written load-path inspection exists.

  Beneteau General Specifications“stainless steel tie rods”

• Working sails lack sufficient cloth strength or shape for the 2028 crossing

  $3k–$22k

  78% likelyexpected $11kinferred

  Reasoning, not a source: The owner confirms all three working sails are original to the 2004 boat. They have no reported tears, holes or patches, but the genoa UV canvas required resewing; 22-year-old appearance is not evidence of cloth strength, seam life or retained shape for a 2028 Pacific crossing.

• Composite rudder stock, blade or bearing structure has moisture, play or damage not cured by the 2024 bushing work

  $2k–$25k

  8% likelyexpected $800inferred

  Reasoning, not a source: Invoice 2020-11891 documents removal of the rudder and replacement of its sleeve bearing. The 2024 invoice documents another cutless bearing, not another rudder bushing. Neither job proves current blade moisture, composite-stock or tube condition.

• Leak or inaccessible damage in the large forward integrated freshwater tank

  $1k–$20k

  12% likelyexpected $840inferred

  Reasoning, not a source: The 2004 manual documents a 90gal forward tank integrated with the structure. The listing gives no pressure-test or repair history.

  Beneteau 423 Owner's Manual“bow tank 340L”

• Known portlight drips have caused hidden joinery or adjacent core damage

  $500–$15k

  10% likelyexpected $400inferred

  Reasoning, not a source: The owner reports minor drips at several Lewmar portlights and has replacement gaskets; all portlight and hatch lenses were replaced in 2018. The known gasket work is separately costed, while concealed damage remains only a conditional risk.

• The 2024 lithium installation requires localized correction

  $500–$12k

  9% likelyexpected $315inferred

  Reasoning, not a source: The installed architecture remains coherent and operational according to the owner, who will supply an updated electrical diagram. Battery brand, BMS, fusing, conductor sizing, busbars, monitoring and charge profiles still require document and visual review.

• Seller-reported autopilot component combination is misidentified or requires localized correction

  $3k–$8k

  50% likelyexpected $2kinferred

  Reasoning, not a source: The owner reports normal operation and identifies a Type 2 linear drive, ACU-200, EV-2 sensor and rudder sensor. Raymarine specifies ACU-200 with Type 1 drives and EV-1 for traditional steering, while Type 2 drives use ACU-400. The most likely explanations are mistaken component names or an incompatible installation requiring ACU/sensor correction.

• The 9.9hp outboard exceeds the exact tender capacity plate or the 2018 RIB needs tube repair

  $300–$5k

  12% likelyexpected $216inferred

  Reasoning, not a source: Current Inmar 9ft 2in Aluma-Lite specifications list a lower maximum horsepower, while XALI carries 9.9hp. Model-year plate and tube condition must be checked.

Systems to check (24)

• Standing riggingasked owner

  Paid 2020 SF Boatworks invoice documents mast unstep/restep, removal and replacement of standing rigging, replacement of headstay wire in the roller furler and final tuning. Parts list includes multiple wire sizes and new terminals. Owner reports chainplates were inspected and verbally judged good; no written chainplate/tie-rod/mast-support report exists.

  SF Boatworks invoice 2020-11891“INSTALL NEW STANDING RIGGING”

• Mast, boom and fittingslisting only

  Conventional fully battened mainsail and mast system are evidenced. Mast, boom, gooseneck, sheaves and corrosion condition are not described.

• Running rigginglisting only

  Seller states the running rigging was replaced in 2020. It will be eight years old at departure but is not assumed to require wholesale replacement without chafe and load inspection.

• Sailsasked owner

  Owner confirms the main, genoa and asymmetric are original 2004 sails with no tears, holes or patches reported. The genoa green UV canvas has been resewn after separating. The green stack pack was replaced in 2018 by NeilPryde. Replacement is not a baseline cost, but sailmaker testing is high priority because all working sails will be about 24 years old at departure.

• Engineasked owner

  Owner confirms 1,609 hours. Data plate reads Volvo Penta D2-55, product 868952, serial 5102972931; it does not display the A/B/F suffix. Reverse gear is MS25L, serial 3581834, product 50250324727. Owner reports all systems operational and accepts an independent Volvo inspection.

• Shaft, coupling, prop, stern glandasked owner

  SF Boatworks 2020 invoice documents a new cutless bearing, packing gland and engine realignment. The 2024 paid invoice documents another Johnson 30x45x120mm cutless bearing and required rudder/prop removal. Owner says mounts are sound but suggests replacement for peace of mind; inspection, not automatic replacement, is appropriate.

• Fuel tanks and systemnot looked at

  Model documentation specifies about 53gal in a rotomolded tank. XALI's cleaning history, inspection access, pickup, vent, hoses and shutoff condition are not stated. inferred

• Electrical, AC and DCasked owner

  Owner will provide an updated diagram for the lithium/solar/DC-to-DC upgrades and says the stock wiring is documented in the printed Beneteau manual. The coherent installed 400Ah lithium, 600W solar, dual Victron MPPT, Mastervolt inverter/charger and 40A DC-to-DC architecture remains credited; verify the diagram, protection and workmanship before pricing localized corrections.

• Battery banklisting only

  400Ah lithium house bank and AGM engine start battery were installed in 2024. Brand, BMS, capacity result and cold-temperature protections are omitted.

• Steering gearasked owner

  Invoice 2020-11891 documents rudder removal and replacement of the rudder sleeve bearing, followed by steering reassembly. The 2024 invoice documents rudder removal for a cutless-bearing job, not a second rudder bushing. Current cable, chain, sheaves, quadrant, stock and emergency-tiller operation remain survey items. inferred

  SF Boatworks invoice 2020-11891“REPLACE RUDDER SLEEVE BEARING”

• Autopilot and self-steeringasked owner

  Owner reports the autopilot operates normally and identifies a Type 2 linear drive, ACU-200, EV-2 sensor core, rudder-position sensor and S100 remote. Raymarine documents ACU-200/EV-1 for Type 1 traditional steering and ACU-400/EV-1 for Type 2 drives. Obtain component-plate photos: this may be simple misidentification or require localized control-unit/sensor correction, but it does not justify a complete new autopilot.

• Hull and laminateasked owner

  Current eight-year owner reports no structural damage or hard grounding; the prior approximately ten-year owner reportedly said the same. The 2018 in-water insurance survey reported no apparent structural delamination but did not inspect underwater gear. Paid 2024 invoice documents two coats of Micron CSC bottom paint.

  2018 Atlas insurance survey“no apparent structural de-lamination”

  SF Boatworks project invoice 1492“Apply two coats of bottom paint”

• Keel and keel boltsasked owner

  Owner confirms XALI has the standard/medium keel at approximately 5ft 7in, passing the 6.5ft hard gate. The 2018 insurance survey says 6ft 4in but also lists plainly erroneous displacement and fuel figures, so its specification block is unreliable; confirm during the purchase haul without treating the deep keel as the current best estimate.

• Rudder and bearingsasked owner

  Paid 2020 invoice documents rudder removal and replacement of the rudder sleeve bearing. Paid 2024 invoice documents rudder removal only as part of replacing the shaft cutless bearing. These are favorable records, but current blade moisture, composite stock, tube and quadrant condition still require inspection. inferred

  SF Boatworks invoice 2020-11891“REPLACE RUDDER SLEEVE BEARING”

• Deck, hardware and hull–deck jointlisting only

  Seller reports annual teak maintenance and good condition. The balsa-cored deck, lifelines, stanchion bases, cleats, chainplates and deck moisture are not independently assessed.

• Through-hulls and seacocksasked owner

  Baja Naval 2018 statement documents replacement of seacocks and through-hulls; owner states the parts were ordered directly from Beneteau. This eliminates any assumed replacement cost. Current survey should operate every valve and inspect backing, hoses, double clamps and material compatibility.

• Plumbing, water tanks and headslisting only

  Approximately 150gal fresh water, dual electric heads and 5gal water heater are listed. Tank integrity, holding tanks, hoses, pumps and valves are not documented.

• Ground tackle and windlasslisting only

  25kg Rocna, 150ft 3/8in BBB chain, 150ft rope, Mantus bridle, Delta secondary and electric windlass are installed. Credit these items; inspect chain, gypsy, windlass and secondary rode.

• Safety equipmentasked owner

  Data plate identifies a six-person Revere Offshore Commander 2.0 with standard emergency pack and 36-month servicing interval. Owner says it was purchased new in 2018 and is due for service. Certified inspection/service or economic replacement is now a known required item. EPIRB model and current battery expiry remain unresolved.

• Electronics and navigationlisting only

  Modern integrated Raymarine suite includes Axiom Pro, nav repeater, Quantum radar, i70 instruments, Class A AIS, fixed VHF and Evolution pilot. Do not budget duplicate plotter, radar, AIS, instruments or network installation.

• Canvas, dodger and coverslisting only

  Sunbrella dodger with Strataglass installed in 2020, plus stack pack and lazy jacks. Bimini, enclosure and foredeck-awning details are omitted.

• Windows, hatches and portsasked owner

  Owner reports minor drips from several Lewmar portlights and has new replacement gaskets aboard. All portlight and hatch lenses were replaced in 2018. Gasket replacement and hose testing are known localized work; hidden moisture or frame-bedding damage remains conditional.

• Dinghy and outboardlisting only

  2018 Inmar 9ft 2in aluminum Hypalon RIB and 2018 Tohatsu 9.9hp four-stroke are included. Credit both subject to tube, seam, capacity-plate and outboard testing.

• Interior and sea berthslisting only

  Two-cabin owner's layout, large forward suite, separate shower, two refrigeration systems, HVAC, diesel heat and electric heads are listed. The forward-cabin headroom is only slightly over 6ft in the published review, a meaningful ergonomic drawback for a 6ft 3in owner. inferred
