1998 Beneteau Oceanis 36 CC "SEQUOIA", Jack London Square Marina, Oakland, CA

Has SEQUOIA ever grounded, struck a submerged object or received repairs to the keel seam, sump, grid or mast-step area?

Damage to the bonded structural grid can be difficult to detect and can exceed the boat's price advantage.

Will the owner permit a complete capacitance moisture map and percussion test of the deck and cabin top?

Wet balsa around fittings, hatches or the mast step could require $9,000-$25,000 of work.

Can the owner supply the most recent survey, insurance-claim history, HIN/title and invoices for the 2023 haul and all major upgrades?

Records can reveal prior findings and substantiate the approximately $7,500 premium over current 1998 comparisons.

Is the 760-hour figure supported by continuous logs, invoices and the original hour meter?

Unverified hours or prolonged inactivity materially changes overhaul and replacement risk.

When were the mixing elbow, injectors, valve clearance, coolant, heat exchanger, raw-water pump and hoses last serviced?

A failed Yanmar mixing elbow can cause water ingestion and major engine damage.

Does the Hansen Rigging invoice include removal or inspection of the shroud chainplates, backstay plates, forestay fitting, internal tie-downs and mast step?

New wire does not retire corrosion or bond problems in the original load path.

Have both freshwater tanks been filled, isolated and pressure-tested, and have any tank fittings leaked?

Large, difficult-to-access tank repairs could cost several thousand dollars.

Which windows, ports and hatches have been resealed or replaced, and will the owner permit a controlled hose test?

Aged seals can damage the interior and adjacent deck core.

What are the manufacture dates, cloth specifications, invoices and latest sailmaker findings for the main, genoa and spare jib?

The answer determines whether roughly $5,500-$12,500 of replacement sails is required.

Has the upper bearing plate or any rudder bearing been replaced, and is there measurable play at the wheel or rudder?

Steering play is a published model-level concern and is passage-critical.

Is any autopilot installed but omitted from the listing; if so, what course computer and mechanical drive are fitted?

Only a properly sized below-deck drive would reduce the catalogue autopilot requirement.

What exact components were included in the advertised 2025 'new main furler,' and can the invoice be provided?

A new line or drum is not equivalent to a renewed mast-furling mechanism.

Are radar or AIS installed but omitted, and what exact model is the VHF with DSC and GPS integration?

Serviceable existing units could reduce major generic equipment lines; otherwise the entire package remains outstanding.

When were the engine mounts, shaft seal, cutless bearing, alignment and propeller last serviced?

Deferred shaft-system work can cause vibration, leakage and expensive haul-out repairs.

Can the July 2023 invoice confirm material, make, backing and hose replacement for all six through-hulls and valves?

The date alone does not establish correct below-waterline installation.

Are a dodger and bimini included, and what are their ages, frame condition and fabric/window condition?

Center-cockpit weather protection is important in the North Pacific and tropics and can cost several thousand dollars to replace.

What is the actual fuel capacity, tank material and date of last internal inspection or cleaning?

Published capacities conflict, and contamination is a passage-critical engine-stoppage risk.

What epoxy system and preparation were used on the iron keel in 2023, and has rust returned at the seam or coating defects?

Poor adhesion can require stripping, fairing and recoating during the next bottom job.

What are the windlass make/model, motor wattage and gypsy size, and what are the chain diameter and grade?

The existing windlass may not accept the planned 5/16in G4 chain and could require replacement.

Who installed the NOCO charger, and are shore-power ELCI/RCD protection, galvanic isolation and charger bank settings documented?

A charger upgrade does not establish that the original AC system is safe or properly protected.

Which running-rigging items were not replaced in 2025, and what are their ages and diameters?

The answer collapses a $900-$3,500 uncertainty and identifies passage-critical old lines.

Why does the DST810 require a new housing, and is the current opening blanked with a manufacturer-approved plug?

The repair involves a below-waterline fitting and may reveal an incompatible or damaged installation.
