The spec change in month 18.

The owner had committed to a 62 m fully custom new build at a top-tier Northern European yard. The contract at signature was EUR 95 m, against a 36-month build window. The owner had retained a brokerage acting in a dual role: the firm had introduced the yard, was acting as owner’s representative on the build, and was being paid by yard commission of approximately 5 percent. The owner had been told, in passing, that this was “the industry-standard structure.” It was, in a narrow sense.

The contract was the yard’s in-house template. The owner’s representative had reviewed it but had not been involved in its drafting. A specialist shipbuilding lawyer had not been engaged. The contract included a change order clause that specified, in general terms, that the yard would price variations at “reasonable cost plus a margin appropriate to the work.” The clause did not specify what reasonable cost meant, what margin was appropriate, or whether the buyer had the right to obtain third-party quotes for variations above a defined threshold.

The change request

Eighteen months in, with the hull complete and outfitting underway, the owner asked for a structural change to the upper deck to accommodate a tender lift the original specification had not anticipated. The change involved reinforcing two structural frames, modifying the deck cut-out, integrating the lift hydraulics, and re-running the deck drainage.

The yard’s change order quote was EUR 2.6 m. The yard’s engineering estimate, which the owner’s representative obtained informally, suggested the actual additional engineering, materials, and labour cost was approximately EUR 1.2 m. The yard’s margin on the change order was therefore approximately EUR 1.4 m, or about 117 percent on the underlying cost.

The owner, on the dual-role representative’s advice, accepted the change order. The representative’s framing was that “changes at this stage of the build always carry a premium” and that “fighting on this issue would damage the relationship with the yard.” Both framings were accurate in a narrow sense. They were also incomplete.

The reason for the premium was not the engineering. It was the absence of a defined change order procedure in the contract. A specialist shipbuilding lawyer would have negotiated unit rates, third-party quote rights, and a variation pricing framework at heads of terms. The owner did not have that framework. He had a general clause that said the yard would charge what it considered reasonable.

Without a defined procedure with pre-agreed unit rates and third-party quote rights, the owner is open to being forced to pay for change orders or emergent work at a unit rate much higher than in the original contract.

The pattern, repeated

The deck change was not the only variation. Across the remaining 18 months of the build, the owner approved 31 change orders totalling EUR 13 m above contract. Approximately 60 percent of those costs were the underlying engineering and materials. Approximately 40 percent was yard margin on the variations.

On a EUR 95 m contract that delivered at EUR 108 m, the owner had paid approximately EUR 5.2 m in variation margin that a properly drafted contract would have constrained. The dual-role owner’s representative’s commission, paid by the yard, was approximately EUR 4.75 m on the original contract value, or about 8 percent of the variation margin paid by the owner.

The owner did not, at any stage, see an invoice from his representative. He paid the yard the contract value plus variations. The yard paid the representative’s commission out of its margin. From the owner’s perspective, he had “saved” a representative fee, because the representative was free.

The independent adviser brought in for delivery

Three months before delivery, with the yard pressing for sea trial scheduling and the snag list growing, the owner engaged an independent adviser to manage the acceptance process. The adviser ran the snag list discipline, the sea trial, the technical handover, and the final acceptance protocol. The adviser’s fee was approximately EUR 180,000 across the four-month engagement.

The adviser’s view, in private conversation with the owner during the acceptance period, was that the contract’s change order framework had cost the owner several million euros across the build, and that the dual-role representative had not been incentivised to negotiate it differently. The owner accepted the analysis. The yacht was delivered on schedule, with a snag list managed to closure within four months of delivery.

The owner’s second build, four years later, was contracted with a specialist shipbuilding lawyer at heads of terms, an independent owner’s representative paid solely by the owner, and a defined change order procedure with pre-agreed unit rates and third-party quote rights. Variation margin across that build was within practitioner industry norms. The contract worked because it had been drafted to.
