A yacht refit in Turkey is signed off in the wrong season

The trial sheet says the generator carried its load for an hour without a fault, and it did. The load came off a bank on the quay, the hall was cold, and nobody was living aboard her. Every figure on the sheet is true, and none of it is the figure she will be judged on in August.

A yacht refit in Turkey is winter work. Winter is the only block of calendar long enough to take steel, fairing and a coating programme in one pass. So she is commissioned, trialled and accepted in the season least able to produce the faults she will actually have.

A yacht refit in Turkey inherits its acceptance season

That the work is winter work is settled elsewhere, in the working year this district keeps. What follows from it, and is never written into a scope, is that the acceptance date inherits the season. Nobody chooses to accept her in February. The booking does it.

Steel closes, the topcoat goes on, systems are commissioned, and she goes out for her trial. A Tuzla shipyard can prove in those months that a system runs. It cannot put that system under the condition it was specified for, because that condition does not exist yet.

A topcoat signed off under roof lights at a refit yard in Tuzla was signed off on film thickness and appearance, not on a season of sun.

Cold water flatters every cooling circuit

Most of what rejects heat aboard rejects it into seawater, and the condition that circuit was sized against is a design seawater temperature on the maker's data sheet rather than the reading on the day of the trial. Which figure applies to her is the maker's. Run the same cooler in colder water and it passes more easily: a fouled tube stack or a throttled branch has margin to hide behind in winter and much less of it in high summer.

A coil dries air only while it runs wet, a separate argument set out in why a cabin can be cold and still damp. What matters here is narrower: the sheet records a cabin temperature and does not say whether the coil it came off was ever asked to run wet.

The hotel load a Turkish shipyard cannot switch on

The hotel load is everything she consumes because people are living on her: galley, laundry, chillers, water maker, hot water, every cabin's air conditioning at once. Almost none of it runs in a winter yard period, because nobody is aboard to run it.

A generator that has never carried her real evening load has not been shown to carry it. A water heater that satisfied its thermostat with one tap open has not been asked what happens when every cabin wants a shower at once. They are the ordinary faults of a season's first weeks.

Flat water is not the sea she will work in

What a trial inside the Marmara cannot buy is a seaway. Deep water is a short run from the yard; weather on order is not. The mechanics of the readings and who signs for them are set out in how a sea trial day is actually run. A trial run exactly as it should be, in deep water, with the owner aboard, still asks nothing of the systems that answer only to a seaway or to a loaded trim.

That some items are proved afloat and nowhere else is understood, and a trials programme is built around it. Being afloat is not the same as being warm: an item can be witnessed and signed and still never have met the temperature it was sized against.

The honest wording on a winter trial sheet is not passed. It is passed under the conditions available.

Witnessed, recorded, or merely energised

Every commissioned item leaves the gate in one of three states, and an acceptance document that does not separate them reads as though all were the first.

• Witnessed. The reading carries its instrument, its location and its date, which is the standard every record here is held to anyway. What makes it witnessed is the condition it was taken at: the one the item was specified for.
• Recorded. It ran correctly and the readings were taken, but not at the condition that matters, because that condition was not available. A cooler proved in cold water sits here, and so does a generator that ran against a load bank and never against her own evening.
• Merely energised. It was switched on and found not to be dead. It is wired and it ran. Nothing about its performance, or its tightness under working pressure, is known.

All three are honest outcomes of winter work. Only the first is what an owner reads into a clean certificate.

A second period in warm weather, or a written proving list

One answer is to bring her back to Turkey for a second refitting period in warm weather, systems loaded and the trial repeated. It costs a second mobilisation and a second delivery passage, neither of which is in the refit price.

The other is to write the gap down before she leaves, and not as a new document. The register a yard already keeps carries a route, a date and a name against each deferred item. What no row carries is the condition: the load, the water temperature or the seaway it still has to be exercised under, and the month that becomes possible in. That column is the change argued for here.

Where a superyacht refit in Istanbul can be witnessed in August

A superyacht refit in Istanbul hands her back a long way from the water the season is spent in, and a warm-weather condition can only be witnessed where she is in August. So a proving list names a place as well as a condition.

A finding that needs no lift, no tenting and no opened structure closes out at Bodrum between charter weeks. One that needs any of the three is a passage north. The people whose word settles some of these tests travel to their own timetable, and a yard cannot requisition one of them.

What the yard answers for in August, and what belongs to the maker

What Reviva answers for after redelivery does not change because the trial was run in February: twelve months on its own workmanship, maker warranties administered alongside it, and a named contact who ran the job. What changes is the evidence that contact has to argue from.

If an item left the gate recorded rather than witnessed, and then fails under load in the heat, what evidence decides whose item it is: the maker's, the installing trade's, or the specification's. That is the question to put to any yard before signing. The conversation about a fault found after she has gone home is shorter when the sheet already said which condition had not been reached.

The winter calendar is what makes a Turkish shipyard refit worth the passage, and the same calendar narrows the evidence it can hand over.

Written at the yard in Tuzla. What we record is what we measure on the job and hand over with the vessel. Rated capacities, design seawater and air conditions, and running limits belong to the maker's data; any contractual test condition to the specialist who wrote it and the surveyor witnessing it; and the dates that govern her to her class society and flag.
