Almost no yard does everything itself. Electrical work, refrigeration, upholstery, rigging, machining, metalwork, glazing and sometimes machinery installation are commonly bought in. That is normal and often better than in-house work of lesser quality. What matters is whether the yard is open about it and manages the interfaces.
- Subcontracting is standard practice; concealed subcontracting is the actual risk.
- Problems concentrate at interfaces, not within trades — someone must own each seam.
- Ask which subcontractors are used, how long the relationship has run, and who supervises their work.
Which trades are usually bought in
Marine electrical and electronics work is the most commonly subcontracted trade, followed by refrigeration and air-conditioning, upholstery and soft furnishing, stainless and aluminium fabrication, sail-making and rigging, and specialised machining. Larger yards may bring some of these in-house; smaller yards rarely do, and there is no reason they should.
A yard with long-standing subcontractor relationships often produces better systems work than a yard that employs a generalist to do everything. The specialists work across many vessels, see more failure modes, and carry equipment and skills that would be idle in a single yard.
The interface problem
Defects cluster where responsibilities meet. The electrician installs to the drawing; the joiner covers the run; nobody checks that the required access panel survived. The machinery installer aligns the engine; the fabricator makes the exhaust; the interface leaks. In each case, both parties did their own job correctly and the vessel has a fault.
The fix is naming an interface owner. On a well-run build that is the yard’s project manager, who sequences trades and verifies handovers between them. Where no such role exists, it defaults to the owner or their representative, and it should be recognised explicitly rather than discovered when something does not fit.
Questions worth asking before you sign
Which trades on my vessel will be performed by subcontractors? Which firms, and how long has the yard worked with them? Who supervises their work and signs it off? Who carries warranty for subcontracted systems — the yard or the subcontractor? And if a subcontractor is unavailable when needed, what is the fallback?
The warranty question is the one owners most often skip and most often regret. A yard warranty that excludes subcontracted systems leaves you chasing several small firms individually for the parts of the vessel most likely to develop faults. A single point of warranty responsibility is worth negotiating for even at a small premium.
Scheduling around specialists
Subcontractors work across multiple yards and multiple vessels, which means their availability is a schedule input the yard does not fully control. A slipped structural phase can push a specialist’s window into a period when they are committed elsewhere, and the resulting wait can exceed the original delay.
This is one of the strongest practical arguments for protecting the early programme. Delays early do not merely shift the end date; they can cascade through third-party availability in ways that multiply. Owners who understand this tend to be much less relaxed about “only a couple of weeks” in the structural phase.
The health of the wider ecosystem
A yard sitting inside a strong local network of suppliers and specialists is materially easier to build with than an isolated one, regardless of craft quality. Spares arrive, a failed part is remade, a specialist can attend at short notice. The same yard in a remote location may build just as beautifully and take twice as long to resolve any problem.
When comparing yards, therefore, look past the site itself to what surrounds it. The ecosystem is part of the purchase, and it is usually invisible in a quotation.
Spares, service and the decade after delivery
The subcontractor network matters long after handover. The firms that installed your refrigeration, electrical and hydraulic systems are usually the ones best placed to service them, and their proximity to where the vessel will operate is a practical consideration that rarely appears in a build decision. A vessel built with equipment that has no service presence in its operating region will spend its life waiting for technicians and parts to travel.
This is a strong argument for specifying equipment with established regional support rather than the theoretically best product from a brand with no local presence. It is also an argument for collecting, at handover, the contact details of every subcontractor who worked on the vessel, along with model and serial numbers for what they installed. That list is worth more in year three than most of the glossy documentation supplied with a new vessel.
Frequently asked questions
Is subcontracting a bad sign?
No. Open subcontracting to established specialists usually produces better systems work than forcing everything in-house. The warning sign is a yard implying full in-house capability that does not exist, because it suggests the interfaces are unmanaged.
Who is responsible if a subcontracted system fails?
That depends on your contract, which is why it should be explicit. The cleanest arrangement makes the yard responsible for the complete vessel including subcontracted work, leaving the yard to manage its own suppliers rather than passing that burden to the owner.
Can I appoint my own subcontractor for a specific system?
Sometimes, and it can make sense for specialised equipment. But it creates an interface you then own, including responsibility for scheduling and for any incompatibility. If you do it, agree the coordination responsibility in writing before the work is scheduled.
