What is checked in a pre-purchase inspection?
The scope may include hull and structure, deck, engines, propulsion, electrical systems, electronics, installations, safety equipment, documentation, sea trial and haul-out.
BOAT INSPECTION
Boat inspection and survey.
Before deciding, it helps to know what is in front of you.
Boat surveys and inspections to understand a vessel’s actual condition and identify defects, errors, issues and risks before making a decision.

WHAT IT SOLVES
A boat inspection or survey assesses the actual condition of a boat to identify defects, issues, repairs, outstanding maintenance and risks within the agreed scope.
WHO IT IS FOR
Buyers who need to know a boat’s condition and owners who want to understand its condition before selling or repairing it.
KEY CONCEPTS
boat inspection · boat survey · pre-purchase survey · pre-purchase inspection · hull · engines · sea trial · haul-out · boat condition · technical report
Does a survey guarantee there will be no future failures?
No. Its purpose is to reduce uncertainty about the observed condition and provide technical information for the decision; it cannot eliminate all future risk.
BOAT CONDITION REVIEW
A good photograph does not show how an engine room has been maintained.
An inspection turns a first impression into specific questions, observations and priorities.
On a used boat, many things do not appear in the advert: corrosion, damp, modified installations, leaks, exhausted batteries, overdue maintenance, incomplete documentation or repairs that deserve closer understanding.
Fontnautic coordinates surveys and inspections adapted to the client’s objective. The scope may be a full pre-purchase inspection, a condition review before selling, a post-purchase check or a reinspection after a repair.
A survey is not a promise that no defect exists. It is a methodical review designed to find errors and issues, check systems within the agreed scope and make clear the boat’s condition and the points requiring attention.
WHEN IT MAKES SENSE
Not every inspection has the same purpose.
Before inspecting a boat, we need to know what decision the inspection should help you make. That defines the depth, specialists, sea trial, haul-out and documentation required.
Before buying
To understand the boat’s condition, identify defects or issues and decide whether to proceed, negotiate, request a specialist review or walk away from the transaction.
After buying
To create a baseline of condition and organise maintenance, urgent actions, upgrades and work that can be scheduled calmly.
Before selling
To identify issues that could arise during a viewing or survey and decide which are worth resolving before putting the boat on the market.
After repairs
To visually check the result of work carried out, verify operation where appropriate and confirm whether any issues remain outstanding.
WHAT WE CAN INSPECT
A boat is a system of systems.
The exact scope is agreed before the inspection. Some components require specialists, diagnostics or specific equipment, which are coordinated when they genuinely add value.
Hull & structure
Visible condition of the hull, gelcoat or paint, joints, accessible bulkheads, reinforcements, signs of repair, impacts, moisture or deformation deserving further investigation.
Deck & superstructure
Fittings, windows, hatches, seals, teak, guardrails, anchor fittings, windlass, passerelle and components exposed to water, sun and loads.
Engines and engine room
General condition, leaks, corrosion, mounts, hoses, cooling, fuel, exhaust, filters, levels, visible maintenance and consistency with the information provided.
Propulsion and steering
Shafts, sterndrives, IPS/pods, propellers, rudders, power steering, transmissions and signs of vibration, play or overdue maintenance.
Electrical systems
Batteries, chargers, inverters, panels, visible wiring, protection devices, connections, corrosion and operation of accessible circuits.
Electronics
Chartplotter, radar, sounder, AIS, VHF, autopilot, instrumentation and other equipment that can be checked during the viewing or underway.
Water, fuel and hydraulics
Pumps, tanks, bilges, sanitation, fresh water, water heater, hydraulic circuits and signs of leaks or irregular operation.
Comfort & auxiliary systems
Generator, climate control, refrigeration, galley, appliances, passerelle, platform, windlasses and other systems relevant to the boat’s actual use.
Safety
Presence and apparent condition of safety equipment, signage and installed items, without replacing any statutory inspections or certifications that may apply.
Documentation and history
Consistency between available documents, engines, modifications, invoices, inspections and the information provided by the owner or seller about the boat.
SEA TRIAL AND HAUL-OUT
Some things only appear when the boat moves. Others only when it comes out of the water.
A sea trial can reveal starting behaviour, temperatures, smoke, acceleration, cruising rpm, vibration, steering, trim, alarms and the operation of certain systems under load.
A haul-out provides access to the underwater hull, propellers, shafts, sterndrives, rudders, seacocks, anodes and areas that cannot be properly assessed with the boat afloat.
Not every inspection includes a sea trial or haul-out. The decision depends on the objective, value of the transaction and the depth the client requires.
SURVEY, VALUATION & ITB
They are different services because they answer different questions.
The survey mainly answers “what condition is the boat in?”. The valuation mainly answers “what is it worth?”. The statutory inspection answers a regulatory requirement.
Understand the actual condition
A technical review aimed at identifying defects, errors, issues, repairs, overdue maintenance and risks. It may include hull, engines, systems, sea trial and haul-out depending on scope.
Assess the boat’s economic value
When you need to know or substantiate a vessel’s value, we coordinate a valuation or appraisal aimed at determining and documenting its technical and economic value.
View surveys and valuations →Statutory inspection
The statutory inspection required by regulation must be carried out by an authorised body. Our private inspection does not replace that obligation.
Documentation and registration →HOW WE APPROACH IT
The inspection begins before we step aboard.
The more information we have beforehand, the more time during the visit can be devoted to checking what matters rather than discovering basic facts as we go.
- 01
Objective
Purchase, sale, condition review, post-purchase, repair or a specific concern. We define which decision the inspection needs to support.
- 02
Preliminary information
Model, year, engines, hours, history, documentation, adverts, photographs, known issues and recent work.
- 03
Scope
What will be checked, whether a sea trial is advisable, whether a haul-out is needed and which additional specialists may be required.
- 04
Inspection
A methodical walk-through of the boat, functional checks within scope and recording of issues or questions.
- 05
Next steps
We organise what has been observed: defects, issues, overdue maintenance, recommended specialist checks and points relevant to negotiation or the decision on the boat.
A SNAPSHOT IN TIME
Inspection reduces uncertainty. It cannot eliminate every possibility of a future failure.
Internal components, intermittent faults and hidden defects may not be revealed by a visual or functional inspection. When a specific sign appears, we therefore recommend going deeper with the appropriate specialist or test.
An engine may require official diagnostics, a hull moisture readings, an electrical installation specific tests or a structure assessment by a qualified technician.
Good judgement also means knowing when to stop looking and start measuring.
BEFORE BUYING A BOAT
An inspection also helps you know which questions to ask the seller.
A clear history, invoices, consistent explanations and a boat that responds well to checks build confidence. Inconsistencies do not always indicate a serious problem, but they do show where further investigation is needed.
How to buy with FontnauticBOAT INSPECTION IN SPAIN
We can assess an inspection wherever the boat is located.
Coverage depends on location, type of boat, depth of inspection and availability of the right professionals. We can assess work across mainland Spain, the Balearic Islands and the Canary Islands.
Where a physical inspection is required, we first check access, haul-out options and the appropriate surveyor or specialist available near the boat.
MARINE SURVEY COST
How much does a pre-purchase boat survey cost in Spain?
The cost of a pre-purchase boat survey depends on length, complexity, location and scope. A visual inspection afloat is not equivalent to a survey covering documentation, engines, onboard systems, sea trial, haul-out and a written report.
Haul-out, travel lift or time ashore are usually marina or boatyard services and may be charged separately. Additional specialists may also be appropriate for engine diagnostics, oil analysis, electronics, moisture readings, rigging or another specific test.
A boat inspection should define in advance what is being checked and what remains outside scope. The aim is not to collect as many tests as possible, but to obtain useful evidence for deciding, negotiating or requesting a specialist review.
Scope matters more than a generic checklist. It should reflect the boat's age, construction, propulsion, systems and specific risk profile.
PRE-PURCHASE SCOPE
What may form part of a survey before buying.
Accessible hull, deck, interior, machinery spaces, installations and system operation within the agreed scope.
Engines under load, temperatures, vibration, steering, alarms, behaviour and systems that can only be assessed underway.
Underwater hull, propellers, shafts, sterndrives, rudders, anodes, seacocks and other submerged components.
Engine diagnostics, oil analysis, rigging, moisture or other tests when there is a technical reason to extend the survey.
BEFORE THE SURVEY
What information should you ask the seller for before the inspection?
Ownership, vessel identification, available certificates and the administrative status of the boat.
Invoices, engine hours, engine services, haul-outs, repairs and significant work.
Recent faults, water ingress, impacts, replacements or systems that are not operational.
Availability of skipper, fuel, boatyard and enough time to complete the agreed survey scope.
FREQUENTLY ASKED QUESTIONS
Frequently asked questions about boat inspection
The scope is defined for each boat and objective. These answers explain how we approach the service.
01What does a boat inspection include?+
The scope is adapted to the boat and the objective. It may include hull and accessible structure, deck, engines, propulsion, electrical systems, electronics, water and fuel systems, safety, documentation and functional checks.
02What is the difference between an inspection or survey and an appraisal?+
An inspection or survey is intended to establish the boat’s actual condition and identify defects, errors, issues, overdue maintenance or risks. An appraisal or valuation has a different objective: to determine and document the boat’s technical and economic value.
03Does the inspection replace the statutory ITB inspection?+
No. Fontnautic’s private inspection does not replace statutory inspections applicable to the vessel or its navigation certificate. Any required ITB inspections must be carried out by authorised bodies under the applicable rules.
04Is it advisable to inspect a boat before buying it?+
For a used-boat purchase, an inspection can provide substantial information before committing to the transaction. Depending on the boat’s value, age, condition and complexity, it may then be reasonable to extend the review with a sea trial, haul-out, specialist mechanic or independent surveyor.
05Does the inspection include a sea trial?+
Not necessarily. It can be included when it adds value and can be arranged. A sea trial allows engines, temperatures, vibration, steering, alarms and certain systems to be observed under load.
06Does the boat need to come out of the water?+
It depends on the objective. A haul-out allows the underwater hull, propellers, shafts, sterndrives, rudders, anodes and seacocks to be reviewed. It may not be necessary for an initial check; for a deeper pre-purchase survey it is often worth considering.
07Do you inspect the engines?+
We can carry out visual and functional checks within the agreed scope. Where there are symptoms, high-value engines or the buyer needs greater depth, it may be advisable to coordinate diagnostics, analysis or inspection with a mechanic or authorised service centre.
08Can you detect osmosis or moisture?+
We can identify signs that justify deeper investigation. Moisture readings, thermography or other specific tests depend on the material, boat condition and equipment required, and may need a specialist technician or surveyor.
09How long does an inspection take?+
There is no single duration. It depends on length, complexity, accessibility, scope, sea trial, haul-out and the number of systems to be checked. The time is defined when the service is planned.
10Do you provide a report?+
The form of delivery depends on the contracted scope. A survey can document observations and defects identified. If what you need is an appraisal or economic valuation of the boat, that is treated as a separate valuation instruction.
11Can you inspect a boat after a repair?+
Yes. We can plan a reinspection or check of the completed work within the possible scope and, where the repair requires it, coordinate the appropriate technician or specialist.
12Do you work throughout Spain?+
We can assess inspections across mainland Spain, the Balearic Islands and the Canary Islands. Specific availability depends on the boat, location, scope and professionals required.
