We call it the Expedition Restomod — restore a proven commercial hull, modify it for modern owner-grade expedition service. Twenty-five years inside the world's premier shipyards taught me one thing the brokerage industry is structurally unable to admit: the boats built to actually go to sea are not the ones marketed to people who go to sea. This is the argument, with the numbers.
A 75-metre white yacht built to MCA LY2 is a vessel optimised for a defined operating profile: Mediterranean and Caribbean cruising, twelve guests, predictable weather windows, marina docking. Hull plate is light. Stability is calculated to a limited operating range. Ice strengthening is rare. Heavy-weather capability is not the design driver.
A 75-metre commercial vessel — an Ulstein UT-design platform supply vessel, a North Sea construction support ship, a research vessel — is built to a fundamentally different brief. The hull is heavier. The frames are deeper. The freeboard forward is built for green water on deck. Ice class is often inherent in the design. Stability is calculated assuming the vessel will be at sea in conditions that would keep a white yacht at the dock.
You cannot retrofit hull plate. You can refit interiors, replace generators, repower, reupholster, and rebuild the wheelhouse. You cannot make a thin hull a thick hull. That decision was made when the keel was laid.
This is the central fact that drives the conversion argument. The most expensive structural decisions on a vessel — hull plate, framing, ice class, stability characteristics — are decisions you inherit when you buy a commercial vessel and decisions you pay for new when you commission a clean-sheet build. Everything else — interior, propulsion package, electronics, deck layout — is rework that the conversion budget pays for and the new-build budget pays for too.
A current Xplorer conversion engagement makes the case in working numbers. The vessel is a 78-metre Ulstein UT-743 platform with DNV ice class, currently available for acquisition at $6 million; conversion package costed at $19 million; $25 million all-in to sea trials.
The conversion arrives on station two years sooner, costs twenty to forty cents on the dollar, and arrives with ice capability already documented by the original class society. The replacement value is real — the underwriter knows it, the insurance market knows it, the resale market knows it — but the capital outlay never approaches it.

Converting an OSV · The Yacht Channel · The Restomod argument in working terms — from offshore vessel to expedition yacht
The conversion argument is correct on the numbers. It is also correct on the personality. The owner who chooses a converted commercial vessel over a 75-metre white yacht is making a choice that most yacht buyers do not make — and most yacht buyers, in fairness, should not.
This owner has typically already owned one or two boats. He has crossed at least one ocean on his own bottom. He has chartered enough white yachts to understand exactly what they do well and what they do not. He values:
There is no judgment in the comparison. A 75-metre white yacht built to LY2 is the right answer for a Mediterranean-summer owner who runs a private and charter programme on the Côte d'Azur. The conversion is the right answer for the owner whose itinerary is on the chart, not the marina map.
A traditional yacht brokerage is structurally aligned with the new-build path. Larger transaction sizes, longer build cycles, more design and project-management billing, and a healthier relationship with the shipyards that pay the brokerage commissions. The conversion path is harder to broker, harder to staff, harder to insure, and pays less when it works.
That is also why we built Xplorer Yachts around it.
“The conversion path is the technically correct answer for a meaningful number of UHNW principals. The industry has spent twenty years failing to advise them on it because the industry is paid more not to.”
Our engagement structure — fixed retainer first, owner-paid representation, transparent disclosure of commission sources — is designed to put us on the right side of that conflict. When the conversion is the better answer, we will tell you so. When the new-build is the better answer, we will tell you so. Both routes pay our practice; both routes have engagements in progress today. The question is which one fits the owner.
The conversion thesis is not universal. There are owners for whom a clean-sheet new build is the right answer, and we represent those owners too — on a separate workstream, with the same independent owner's-representation discipline.
We have active engagements in all four categories. The point is not that conversion always wins. The point is that conversion is the technically and financially correct answer for a meaningful share of expedition-yacht buyers — and that share is structurally under-represented in the brokerage market.
If you have an active expedition-yacht decision in front of you — acquisition, Restomod, or new-build — we will walk you through the numbers on each route as they apply to your specific brief. The first call is on us; the engagement letter follows when there's a working brief.
