Everyone Read the D-Marin Deal Wrong

"Isn't maritime a bit niche?"

That was the most common reaction when we began raising a fund for maritime leisure software. It became harder to maintain this month.

InfraVia Capital Partners agreed to purchase D-Marin from CVC Capital Partners. The Financial Times reported the price exceeded €1 billion. With D-Marin generating approximately €70 million in annual EBITDA, that implies a multiple around 15x: the profile of an infrastructure asset, not a niche market.

Most coverage of the deal missed what actually changed hands.

What Actually Changed Hands

D-Marin operates 28 premium marinas across nine countries, serving over 50,000 customers a year and managing more than 14,300 berths, including over 1,000 dedicated superyacht berths. The business also runs 12 professional boatyards servicing roughly 2,500 yachts annually.

CVC bought the business from Turkey's Doğuş Group in 2020, installed new management under CEO Oliver Doerschuck, and expanded it from Turkish, Croatian, Greek and UAE markets into Spain, Italy, France, Malta and Albania. The sale to InfraVia was run at full institutional scale, with Goldman Sachs and Clifford Chance advising CVC, and Morgan Stanley and White & Case advising InfraVia.

One Deal Is an Anecdote. Three Is a Pattern.

D-Marin is not an outlier. It's the latest entry in a repricing that has been building for two years:

• Blackstone's infrastructure division agreed to buy Safe Harbor Marinas, the largest U.S. marina owner, from Sun Communities for $5.65 billion in early 2025
• MarineMax paid $480 million for superyacht marina specialist IGY in 2022
• InfraVia itself acquired an 80% stake in LD Armateurs, a French maritime transport and offshore services business, in July 2025

Major institutional capital has decided marine leisure infrastructure is a durable, ownable asset class: scarce waterfront, resilient demand, predictable revenue.

The Detail Everyone Skipped

Buried in the announcements is the part that actually matters. Alongside its geographic expansion, D-Marin invested heavily in building what it calls one of the most technologically advanced operating and customer platforms in the industry: a unified system managing marinas, reservations and boat owner relationships. That platform is repeatedly cited as core to the valuation.

Which means a meaningful share of the value inside a €1 billion infrastructure asset comes from software, not concrete. Berths are finite. Operating systems are not. And across maritime leisure, software still touches less than 2% of a market worth over €130 billion.

Why This Is the Whole Thesis

We didn't found Ocean One Ventures to own marinas. We founded it because founders are building the software that operators like D-Marin will not be able to operate without: charter platforms, marina operating systems, compliance automation, broker marketplaces, superyacht management suites, all still at sub-2% penetration inside a billion-euro network.

It's a familiar sequence: physical assets consolidate and institutionalise first, then the operating layer gets built, acquired and repriced. Maritime leisure is early in that sequence, at pre-seed and seed, before infrastructure funds start chasing software as hard as they chase ports.

For maritime software founders, the buyers of customer bases have shown their hand: building the operating layer for a €1 billion asset is infrastructure, not niche. For capital allocators, the question has narrowed from "is maritime leisure large enough" to "who builds the software layer the next D-Marin acquisition will require."

Eighteen months ago I was answering the niche question. This week the market answered it for me.
