Quick Verdict
- Sanlorenzo's steel flagship: 210'0" and 1,300 GT across five decks, with a private owner's deck of its own
- The main aft deck and the beach club are integrated by design so the social life on board is not split between two levels — the yard's own stated reasoning for the layout
- Twin MTU 12V 4000 M63s at 1,500 kW (2,012 HP) each for a published 16 knots, with 120,000 litres of fuel, 12 guests and 13 crew
Our Take
The 64Steel is Sanlorenzo's steel flagship, and the thing that makes it interesting is a layout argument rather than a number. The yard's stated intent is to integrate the main aft deck and the beach club as much as possible, so that the social life on board is focused in one place instead of separating the guests. Anyone who has spent time on a 200-footer knows the problem that solves: past a certain size the boat gets so large that everyone ends up in a different part of it. Sanlorenzo joined the two spaces people actually use and put a private owner's deck above them. That is a real answer to a real problem.
The figures: 210 feet, 1,300 gross tons across five decks, an 11.9-metre beam, twin MTU 12V 4000 M63s at 1,500 kW — 2,012 horsepower — each, a published 16 knots, 120,000 litres of fuel, twelve guests and thirteen crew. Look hard at that last pair. Thirteen crew for twelve guests is what a properly run vessel of this class looks like, and it is a truer indication of what you are taking on than any dimension on the list. And be clear that 1,300 GT is gross tonnage — enclosed volume, not weight. It is the most misquoted number in this part of the market.
Two cautions, and both are about paperwork. First, published figures for this model are not consistent from one source to another, so get the length overall, the certified gross tonnage and the engine package confirmed in writing by the yard for the specific hull before you rely on any of them — do not assemble a specification from listings. Second, Sanlorenzo publishes no draft, no cruise speed, no range, no fresh water capacity and no displacement here, and at 210 feet the missing draft is the one that decides where you can actually go. Get all five from the build specification. And treat the interior photography as one owner's fit-out rather than the standard boat: this yacht is delivered bespoke, so what carries across the range is the deck arrangement and the volume, not the finishes you are being shown.

Frequently Asked Questions
64Steel or 58Steel — how do I choose?
Propulsion and guest count, not speed. The 64Steel is 64 metres (210 feet) and 1,300 GT, twelve guests and thirteen crew, on twin MTU 12V 4000 M63s for 16 knots. The 58Steel is 58.25 metres (191 feet 1 inch) and 1,165 GT, ten guests and thirteen crew, and it is the first diesel-electric yacht in the yard's steel line — twin E-Pods at 850 kW each, with published figures for hotel mode at anchor without generators running.
So the 58Steel is the one to look at if quiet time at anchor and the diesel-electric architecture are what you are buying. The 64Steel is the one to look at if you want two more guest places, a private owner's deck and the largest steel hull Sanlorenzo currently publishes. Crew is thirteen either way.
What power and speed does the Sanlorenzo 64Steel have?
Twin MTU 12V 4000 M63 engines at 1,500 kW (2,012 hp) each, for a published maximum of 16 knots. Fuel capacity is 120,000 litres (31,701 US gallons) — by a wide margin the largest tank in the Sanlorenzo fleet covered here, and the figure that most clearly separates the 64Steel from the sub-500 GT steel yachts below it.
Sanlorenzo publishes no cruise speed and no range for the 64Steel, so 16 knots is the only speed figure the yard stands behind. The 64 metres (210 feet) sits on an 11.9-metre (39 feet 1 inch) beam at 1,300 GT, gross tonnage being a measure of enclosed volume rather than weight.
Why do published figures for the Sanlorenzo 64Steel disagree?
Because the yard and its distributor network publish different numbers, and the two should not be blended. Sanlorenzo's own current page gives 64 metres, 1,300 GT, twin MTU 12V 4000 M63s and 120,000 litres of fuel. Its UK distributor publishes 61.50 metres, 1,350 GT, twin Caterpillar 3516C engines, 16.5 knots and 130,000 litres.
We use the yard's figures throughout, because the builder is the primary source. Averaging the two sets, or taking a length from one and a tonnage from the other, would describe a yacht that does not exist. For a specific hull, the build specification and the flag documentation carry the numbers that actually apply to it — and those can differ from a series specification in either direction.
How many cabins does the Sanlorenzo 64Steel have?
Sanlorenzo does not publish a cabin count. It publishes twelve guests and thirteen crew across five decks, which is how the yard specifies accommodation throughout its fleet — the number of staterooms and their arrangement is settled in the build specification for each hull.
What the yard does describe is the structure: a private owner's deck above, and a main aft deck arranged to run into the beach club so guests are not split between two separate social areas. Exterior lines are by Officina Italiana Design, interiors by Francesco Paszkowski and Margherita Casprini. One caution when you look at 64Steel interior photography — it shows a delivered owner's fit-out, so read what you see as one owner's choices rather than as a standard specification.
