What access a yacht surveyor should have and what a refusal tells you

Access is settled before the survey, not during it

This is the part buyers leave until it is too late. Almost nothing on that list can be arranged on the morning of the inspection. Clearing a tank takes planning and costs money. Booking a lift takes a yard slot. A sea trial needs the vessel crewed and fuelled and taken to sea. Making crew available means telling them a week beforehand.

A seller who has not agreed to those things in advance has every practical reason to decline once the surveyor is standing on the deck. The surveyor has no leverage at that point. The buyer ends up paying for a narrower examination than the one they thought they had commissioned.

Agreeing access in writing beforehand does something else useful. It removes the later argument about what the survey was supposed to cover. That argument surfaces at exactly the wrong moment, when findings are being discussed and a notice period is running.

Which panels come off

The requirement is not that every panel in the vessel comes off. It is that the panels come off which expose the structure behind the linings and the deckheads.

A yacht interior is built to conceal the vessel. Joinery, headlinings, wall panels and soles exist to make machinery, structure and services invisible. They do that job extremely well. What sits behind them is the part that matters. Frames and stringers. Bulkhead connections. The inside face of the shell, the welds or laminate, the insulation and the cable and pipe runs that thread through all of it.

Two of those deserve particular mention.

• Corrosion beneath insulation. On a steel vessel, insulation that has taken up moisture holds it against the plate. The deterioration is progressive and entirely hidden. It gives no external sign until it is advanced. Nobody finds it from the accommodation side of a lining.
• Connections and penetrations. Problems concentrate where structure meets structure and where services pass through structure. Those points are almost always behind something.

This is also why an immaculate interior is not the reassurance it appears to be. A beautifully finished vessel is a vessel whose condition is comprehensively covered up. The finish tells you about the last refit rather than about the hull.

Tanks, opened and cleared

The inside of a tank cannot be assessed from the outside. Coating breakdown. Corrosion and pitting. The condition of baffles and internal structure. Accumulated sludge. Water lying at the interface with fuel. These are internal conditions with no external symptom until they produce a failure or a contamination problem.

Clearing a tank means emptying it and making it safe. Entry into an enclosed space is a serious procedure with its own safety requirements rather than a matter of lifting a lid. It is a real imposition on a seller in time and in cost. That is precisely why it belongs in the agreement rather than in a request on the day.

It is also why a refusal here is worth understanding rather than assuming. A seller may have sound reasons. The point is that the buyer should know which tanks were examined and which were not. That should reach them as a stated limitation rather than as a silence.

Every space aboard

The general principle is admission to the whole vessel. The spaces most often quietly omitted are the ones worth seeing.

• Crew accommodation. Frequently excluded for privacy. It contains structure and systems like anywhere else.
• Voids, cofferdams and bilges. Where water collects and where corrosion shows itself first.
• Steering gear compartments, thruster spaces and chain lockers. Wet, hard-working and rarely visited between surveys.
• Machinery spaces in full. Behind and beneath the machinery rather than the walkway view of it.

What a stuck hatch tells you

One of the more useful things a surveyor meets is an access hatch that will not open. Painted over. Fastenings seized in place.

That is a finding rather than an obstacle. If the hatch cannot be opened without breaking the paint then nothing behind it has been inspected either, for however long it has been in that state. The space should be treated as unexamined. The report should say so plainly.

It also raises a fair question about the maintenance record. A record showing work in a space nobody can enter does not reconcile. We have written separately about what the maintenance record shows that the vessel cannot. This is one of the places the two lines of enquiry meet.

The separate exercises

Two things buyers commonly assume are included are usually not. Both need arranging well ahead.

Underwater inspection. Assessing the hull below the waterline, the running gear, rudders, stabiliser fins, anodes and sea inlets requires the vessel lifted or a diver in the water. It is commissioned in addition to the inspection aboard.

Sea trial. Machinery reveals itself under load in ways it will not alongside. Temperatures. Pressures. Vibration. Alignment behaviour. Steering and stabiliser performance. The behaviour of systems when they are actually working. Those are trial observations rather than dockside ones. A sea trial needs the vessel crewed and fuelled and taken to sea. That is why it sits outside a standard scope and is arranged separately.

Neither of these is exotic. They are simply not automatic. The time to establish whether they are wanted is when the survey is being planned rather than when the report arrives.

Reasons a seller may say no

It is worth being fair about this. Treating every refusal as evasion is both wrong and counterproductive.

A vessel in active charter has commitments. Clearing tanks costs money and takes the vessel out of service. Yard slots for a lift are not always available at short notice. Crew may be on leave. An owner may reasonably hesitate before allowing sealed or warranted equipment to be opened. Several of those are entirely legitimate and can be worked around by scheduling rather than by argument.

What matters is that the reason is asked for and recorded. The resulting limitation should appear in the report rather than being smoothed over. A stated limitation is honest and lets the buyer decide. An unstated one becomes a claim about condition that nobody actually verified.

Why the limitation matters later

This becomes concrete at the point the findings are used. A surveyor cannot certify the condition of something they were prevented from examining. A report that quietly implies otherwise is worse than one that states the gap. It will not survive a second professional reading.

The practical consequence for a buyer is straightforward. Every area excluded from the examination is an area where they carry risk they have not priced. They should know which areas those are before deciding what to do next. That decision and the routes available once findings are on the table are covered in what happens after a survey finds defects.

What to settle in writing, before anyone boards

• Panels to be opened where they expose structure behind linings and deckheads.
• Which tanks are to be opened and cleared. Who arranges and pays for it.
• Admission to every space aboard, crew areas and machinery spaces included.
• Whether the vessel is to be presented dry and powered, with machinery available to be run.
• Whether an underwater inspection is wanted. Who arranges the lift or the diver.
• Whether a sea trial is wanted. Who crews and fuels it.
• Which records are to be produced before boarding.
• The reporting turnaround, in writing.

Some of these may already be dealt with by the sale agreement. The standard industry forms address parts of the survey arrangement including who bears certain costs. Read your own executed agreement and take advice on it. Do not assume either that it covers these points or that it does not.
