The Sanlorenzo 50X-Space: Same Numbers as the 50Steel, Different Boat

Quick Verdict
- 499 GT on a 164'1" hull with twin MAN D2862-LE489s for a published 16 knots — the larger of Sanlorenzo's two X-Space superyachts
- Dimensionally near-identical to the 50Steel: the same 50 metres, the same 9.30-metre beam, the same 499 GT and the same 55,000 litres. The aft open-air living room and its folding balconies are what actually separate them
- Sanlorenzo has designated this the model to introduce its bi-fuel green methanol propulsion, developed with MAN — announced, and not yet delivered
Our Take
The 50X-Space presents a problem that most reviews will get wrong: on paper it is the 50Steel. Fifty metres, a 9.30-metre beam, 499 gross tons, the same MAN pair, the same 55,000 litres. If you are cross-shopping the two on a spec sheet you will conclude they are the same boat with a different badge, and you will be wrong. What you are buying with the X-Space is the aft open-air living room and the folding balconies that open it further — a decision about where the boat's life happens when it is stopped, which on a yacht used mostly at anchor is not a detail.
The other reason to care about this hull specifically is that Sanlorenzo has chosen it to introduce a bi-fuel green methanol package developed with MAN. That is a real move by a serious builder and it is worth understanding properly. It is also announced rather than delivered, and I would treat every part of it as a question: is it standard or optional on your hull, what does it displace in the engine room, what does it cost you in tank volume, where can you actually bunker it on the routes you intend to run, and what does it change about how the crew operate the boat. Those all have answers. None of them are on a brochure.
Two limits to be straight about. First, there is no delivered 50X-Space — every image published so far is a rendering, and Sanlorenzo does not currently carry the model on its own fleet site, so the specification here comes from the yard's archived page and its official distributor network. Anyone describing what it feels like on board is describing a computer model. Second, the usual Sanlorenzo gaps apply and they are wide: no cruise speed, no range, no fresh water capacity, no displacement, and no published kilowatt rating for the MAN package on the archived specification. At 164 feet you should have all of those in the build specification before you sign anything, and you should get the general arrangement for both this boat and the 50Steel and put them next to each other. That comparison, not the spec sheet, is the actual decision.

Frequently Asked Questions
Should I look at the 50X-Space or the 52Steel?
They answer different questions despite landing within two metres of each other. The 50X-Space is 50 metres (164 feet 1 inch), 499 GT, twelve guests and nine crew, in a navetta-explorer shape built around volume and open-air aft living. The 52Steel is 51.6 metres (169 feet 3 inches), under 500 GT, up to twelve guests and nine crew, and in its current NEO form it moves the tender and toy garage forward to the bow so the whole aft end becomes beach club and wellness space.
Both use twin MAN D2862-LE489s and both top out at 16 knots, so this is not a performance decision. Neither has a delivered hull to walk today, so both are specification exercises. The 52Steel is the one with a live page on Sanlorenzo's own site and a clearly defined NEO brief.
What accommodation does Sanlorenzo publish for the 50X-Space?
Twelve guests and nine crew. Sanlorenzo lists guest and crew numbers rather than cabin counts, so the number of staterooms and how they are arranged belongs to an individual hull's build specification rather than to the model.
Because no 50X-Space has been delivered, there is no completed interior to describe and no fixed general arrangement in the public record. The published envelope is a 50-metre (164 feet 1 inch) hull on a 9.30-metre (30 feet 6 inches) beam at 499 GT — deliberately under the 500 GT line, as with its 496 GT sister. Gross tonnage measures enclosed volume rather than weight, and Sanlorenzo publishes no displacement figure for either X-Space model.
What engines and speed does Sanlorenzo publish for the 50X-Space?
Twin MAN D2862-LE489s and a maximum of 16 knots. That is the propulsion Sanlorenzo published for the 50X-Space, alongside 55,000 litres (14,529 US gallons) of fuel on a 50-metre (164 feet 1 inch) steel hull. No cruise speed is published, and no range.
The 50X-Space is also the model Sanlorenzo named to debut its bi-fuel green methanol propulsion. Treat that as a stated programme rather than a delivered specification — no hull has been completed, so there are no observed figures behind it. Beam is 9.30 metres (30 feet 6 inches) and draft at full load 2.96 metres (9 feet 9 inches).
Has any Sanlorenzo 50X-Space been built?
No. The 50X-Space exists as design and renderings — no hull has been delivered, so nobody has been aboard one and there are no observed performance or handling figures for it. Sanlorenzo does not currently carry a live 50X-Space page on its own website either; the specification survives from the yard's earlier site and through its distributor network.
That shapes how you should read every number attached to it. The 50 metres, 16 knots, 55,000 litres and twelve guests with nine crew are the yard's own published design figures, and the 499 GT comes from within Sanlorenzo's own network. Anything beyond those — cruise speed, range, fresh water capacity, weight — is not published at all. Treat the 50X-Space as forthcoming, and specify it from build documents rather than from a brochure figure.
