Pre-Purchase Yacht Survey Checklist Spain

A pre-purchase yacht survey checklist helps buyers understand what to inspect before buying a yacht in Spain.

Pre-Purchase Yacht Survey Checklist

This checklist is not a substitute for an independent yacht survey report, but it helps the buyer prepare for the inspection, ask better questions and understand the technical areas that may affect the purchase decision.

A professional pre-purchase yacht survey in Spain should review the yacht’s structure, hull, deck, machinery, systems, documentation, safety equipment and underwater areas when haul-out is available.

Why a Pre-Purchase Yacht Survey Checklist Matters

Buying a yacht without a proper inspection can expose the buyer to hidden defects, previous repairs, osmosis, machinery issues, electrical problems, rigging concerns, safety deficiencies and unexpected repair costs.

A structured yacht survey checklist helps make the inspection process more complete, consistent, and useful for purchase negotiations, insurance acceptance, and repair planning.

Hull & Structure

The hull and structure are among the most important parts of a pre-purchase yacht survey. The surveyor may inspect the general hull condition, deck condition, bulkheads, internal structure, keel attachment, rudder area and visible signs of impact, grounding or previous repairs.

Important checks may include:

  • Hull condition.

  • Deck condition.

  • Bulkheads and internal structure.

  • Keel attachment.

  • Rudder and steering system.

  • Visible signs of impact or grounding.

  • Previous repairs or structural modifications.

Moisture and Osmosis Indicators

For GRP and fibreglass yachts, moisture and osmosis indicators should be reviewed carefully. Moisture readings may be taken where appropriate, but they must be interpreted in light of haul-out time, hull condition, coatings, weather, and drying period.

The surveyor may check:

  • Moisture readings were appropriate.

  • Visible osmosis indicators.

  • Blisters or laminate defects.

  • Coating failure.

  • Previous osmosis treatment.

  • Antifouling and hull coating condition.

Underwater Hull and Fittings

When haul-out is available, the underwater section should be inspected. This is essential because many expensive defects cannot be properly assessed while the yacht is afloat.

The surveyor may inspect:

  • Keel and keel joint.

  • Rudder and steering appendages.

  • Propeller.

  • Shaft or saildrive.

  • Anodes.

  • Through-hull fittings.

  • Seacocks.

  • Bow thruster area.

  • Visible grounding damage.

Machinery & Propulsion

A pre-purchase yacht survey normally includes a visual assessment of the machinery and propulsion systems. This is not the same as a full mechanical engine survey, but it can identify visible defects, maintenance issues and risk indicators.

Checks may include:

  • Engine visual condition.

  • Generator visual condition.

  • Engine mounts.

  • Cooling system.

  • Fuel system.

  • Exhaust system.

  • Leaks or corrosion.

  • Signs of poor maintenance.

Electrical and Navigation Systems

Electrical systems are important for safety, reliability and insurance acceptance. The surveyor may review visible electrical installations, batteries, panels and navigation equipment.

The inspection may include:

  • Batteries.

  • AC/DC panels.

  • Wiring condition.

  • Shore power.

  • Charging systems.

  • Navigation electronics.

  • Communication equipment.

  • Visible installation defects.

Safety Equipment

Safety equipment should be checked according to the yacht type, intended use and available documentation.

The surveyor may inspect:

  • Lifejackets.

  • Fire extinguishers.

  • Bilge pumps.

  • Navigation lights.

  • Emergency equipment.

  • Gas installation where applicable.

  • Liferaft documentation was available.

Rigging and Deck Equipment

For sailing yachts, the rigging and deck equipment should be reviewed from deck level unless a specialist rigging inspection is arranged.

The surveyor may check:

  • Standing rigging from deck level.

  • Running rigging.

  • Winches.

  • Deck hardware.

  • Mast fittings visible from deck.

  • Sails where available.

  • Signs of corrosion, wear or damage.

The inspection may include:

  • Leaks.

  • Corrosion.

  • Bilge condition.

  • Joinery condition.

  • Plumbing systems.

  • Tank areas where accessible.

  • General maintenance.

Documents may include:

  • Registration documents. Builder information.

  • CE documentation where applicable.

  • Maintenance records.

  • Engine service records.

  • Previous survey reports.

  • Invoices for major repairs or refits.
