Hey friends,

Here's something most people in maritime don't know: while Maersk, MSC, and CMA CGM were fighting brutal price wars and chasing market share in container shipping, a Spanish family business quietly built a more profitable, more defensible empire.

They did it without fanfare. Without press releases about mega-alliances. Without a single LinkedIn thought leader writing about their "disruption."

They operate 400+ vessels across 100 ports in 18 countries. Annual revenue approaching €1 billion. And if you work in a European port, you've almost certainly used their services—even if you didn't realize it.

Meet Boluda Corporación Marítima. The towage giant nobody talks about.

Towage is simple: tugboats help ships maneuver in and out of ports. Without them, container ships can't dock. LNG carriers can't berth. Cruise ships can't turn around. The entire port grinds to a halt.

It's infrastructure disguised as a service.

Founded in Valencia in 1837—yes, nearly 200 years ago—Boluda started with one thing: moving ships safely in port. While others diversified into logistics, freight forwarding, and terminal operations, Boluda stuck to what they knew.

Here's the interesting part: that focus made them richer than most companies that tried to do everything.

Boluda's strategy is almost boring in its simplicity: own tugboats, provide towage services, repeat.

They don't own container ships. They don't run freight forwarding operations at scale. They don't compete with Kuehne+Nagel or DHL. They just pull ships into port—and they're really, really good at it.

Why does this work? Three reasons:

First, recurring revenue. Ports need towage for every ship movement. It's not project-based. It's not seasonal. Ships arrive, ships depart, tugboats work. The demand is constant and predictable.

Second, switching costs. Once Boluda establishes operations in a port, moving to a competitor means retraining crews, renegotiating port authority contracts, and proving safety records all over again. Most shipping lines don't bother. The risk isn't worth the marginal cost savings.

Third, pricing power. When you're the only game in town—or one of two providers—you set rates. Boluda doesn't compete on price. They compete on reliability, and reliability in towage means everything. A delayed ship costs thousands per hour. Nobody haggles over a €2,000 tug job when the alternative is a €50,000 port delay.

Their fleet now stands at over 400 vessels operating across Europe, Africa, Latin America, and Asia. That's infrastructure at scale.

Boluda didn't get to 400+ tugs by building them all from scratch. They bought their way to dominance—but intelligently.

In 2019, they acquired Kotug Smit Towage for €300 million. That single deal added 67 tugs and gave them presence in Rotterdam, Antwerp, Liverpool, Southampton, London, and Hamburg. Overnight, they became the European leader.

Here's what most companies get wrong with acquisitions: they gut the business, rebrand everything, and destroy the local knowledge that made it valuable in the first place.

Boluda did the opposite. They kept the crews. They kept the port relationships. They kept the operational expertise. They just painted the tugs in Boluda colors and integrated the back office.

Why? Because towage is local. A tug captain who's navigated Rotterdam for 20 years knows things a corporate manual never will. The tides, the currents, the quirks of specific berths. That knowledge is the product.

They repeated this playbook across Europe:

Each acquisition followed the same pattern: buy established operators, keep local expertise, integrate systems, expand fleet capacity.

And they were selective. In 2023, Boluda announced plans to buy Smit Lamnalco—111 vessels, operations in Australia and the Middle East—which would have made them the undisputed global leader. The deal collapsed in 2024 due to regulatory issues with Russian-held assets.

Instead of panicking, Boluda pivoted. In 2025, they bought just the Australian and Papua New Guinea operations from Boskalis for $640 million, cherry-picking the best assets without the regulatory headaches. That's disciplined M&A.

Let's talk numbers.

Boluda Corporación Marítima reported €978 million in revenue for 2023. For context, Svitzer (Maersk's former towage arm, now spun off) did $839 million with 446 vessels across 141 ports.

Similar revenue, similar fleet size. The difference? Boluda is family-owned and profitable. Svitzer was spun off because Maersk couldn't justify keeping it.

Here's why towage economics are so attractive:

Capital-intensive but predictable. A modern tug costs €5-15 million depending on specifications. That's expensive upfront, but the asset lasts 25-30 years with proper maintenance. Once deployed, it generates steady cash flow with minimal variable costs.

Long-term contracts. Most port towage contracts run 5-10 years. Boluda signs with port authorities or major shipping lines, locking in revenue years in advance. There's no month-to-month uncertainty.

High barriers to entry. You can't just show up in Rotterdam with a tugboat and start competing. You need port authority licenses, insurance, trained crews, 24/7 dispatch operations, and years of safety track records. The regulatory moat alone keeps most competitors out.

This is why private equity loves towage companies—and why Maersk decided it was better off as a standalone business than as part of an integrated logistics empire.

Boluda's competitive advantage isn't technology. It's not innovation. It's not "disruption."

It's relationships and regulatory lock-in.

Port authorities don't switch towage providers easily. The approval process takes months. Safety records get scrutinized. Insurance has to be re-verified. Crew certifications need validation. It's bureaucratic friction at its finest—and it protects incumbents beautifully.

Add to that the capital requirement (you need 10-20 tugs minimum to serve a major port efficiently) and the 24/7 operational commitment (tugboats don't take weekends off), and you have a business that's nearly impossible to replicate from scratch.

Boluda also benefits from scale economies. With 400+ tugs, they can move vessels between ports during demand spikes, share maintenance facilities, and negotiate bulk fuel purchases. A regional competitor with 15 tugs can't match that operational flexibility.

The result? Once Boluda enters a port, they rarely leave.

Boluda's story isn't just about tugboats. It's about how to build defensible market positions in service businesses.

Lesson 1: Specialization beats diversification when you dominate.
Boluda could have expanded into ship management, freight forwarding, or terminal operations. They didn't. They stayed in towage and became the best at it. That focus created pricing power. Most companies dilute themselves trying to do everything. Boluda got rich doing one thing exceptionally well.

Lesson 2: Assets + relationships = moats.
In B2B services, the combination of hard assets (tugboats) and soft assets (port relationships, safety records, crew expertise) creates barriers competitors can't easily cross. Think about your own business: where do you have this combination?

Lesson 3: Smart acquisitions preserve what works.
Boluda didn't destroy the companies they bought. They integrated systems but kept operational knowledge intact. Too many acquirers optimize for efficiency and lose the expertise that made the target valuable. That's expensive arrogance.

Lesson 4: Patient capital wins.
This is a family business playing a 50-year game. They're not optimizing for quarterly earnings or investor presentations. They're building an empire that compounds value over decades. That patience creates strategic optionality others don't have.

On Monday, look at your vendor relationships differently. Ask: which suppliers have real power, and why? Is it just price, or do they have Boluda-style moats—assets, relationships, and switching costs that make them effectively irreplaceable?

The companies nobody notices are often the most valuable. Boluda proves it.

Cheers,

Fernando
