West Sea's third drydock will cost roughly €24 million, up from about €4 million when the project was first floated in 2020 — a sixfold increase that pushes completion back to 2028 and caps how much of Europe's small-ship refit boom the Portuguese yard can capture.

The delay, which the West Sea blames on an environmental impact study, was confirmed by the Viana do Castelo city council, which approved tax incentives for the 220-by-45-meter facility in February 2025. For a yard sitting on one of Europe's busiest small-ship orderbooks, the missing dock is the difference between competing for larger cruise and commercial contracts and watching them go elsewhere.

What's filling the two docks it already has?

The existing pair is running hot. West Sea delivered the Star Seeker to Windstar last December and is now converting the World Explorer into the Star Explorer, due to debut in December 2026. The refit strips out the vessel's expedition features for a full luxury conversion — a different engineering job entirely from a newbuild.

Nearby sits the Sefu, a 10,000-ton yacht-style vessel for Japan's R Yacht, a new luxury cruise brand. That's three distinct customer types — a US small-ship operator, a Japanese entrant, and the Portuguese Navy — inside one facility.

The naval side alone guarantees years of work. The Portuguese Navy has six ocean patrol vessels on order, from the Porto, reportedly due in 2027, through later hulls such as the Aveiro, due in 2028.

In plain terms: the yard's revenue base is booked out well past the drydock's new completion date.

Is the diversified bet actually working?

Board member Vitor Figueiredo frames the cruise-naval-commercial mix as deliberate strategy, not accident. "Rather than just focusing exclusively on a single market, West Sea's approach is to maintain the ultimate flexibility to respond to whatever the customer needs and market demands," he said.

That's a reasonable hedge in a cyclical shipbuilding market — naval contracts don't vanish when cruise capital expenditure cools. But note what the yard isn't saying: it offers no revenue figures, no margin data, and no breakdown of how the €24 million overrun will be funded beyond municipal tax relief. Martifer Group, the parent that took over the former state-owned ENVC yard after its 2014 liquidation, hasn't disclosed what the delay costs in foregone contracts.

Figueiredo points to execution as the proof point. The Star Seeker and Star Explorer, he said, "reinforce the importance of much detailed planning, lots of close collaboration with both owners and the suppliers, and then rigorous project execution from our side." Two delivered-or-underway Windstar projects are real results, not projections — though a sample of two is thin evidence for a strategy thesis.

What changes when the third dock opens?

Per the yard, the new 220-meter facility should let West Sea compete for larger cruise and commercial projects than its current infrastructure can accommodate. The 45-meter width matters for sellers of travel indirectly: more refit capacity in Europe means shorter off-hire periods for operators like Windstar, which translates to more sellable inventory months per ship per year.

Until 2028, though, that capacity simply doesn't exist. Every large contract West Sea pitches in the interim is a promise the yard can't yet physically honor — and the sixfold cost climb suggests the timeline could slip again.

Viana do Castelo's shipbuilding roots stretch back centuries, predating Martifer's 2014 takeover. Heritage doesn't win contracts; dock space does, and West Sea won't have enough of it for at least three more years.
