The 58Steel is the most technically interesting boat Sanlorenzo currently builds, and the reason is the propulsion. This is the first diesel-electric system in the yard's steel line — twin E-Pods at 850 kW each — and Sanlorenzo puts real numbers against it: around 10% lower emissions, up to two hours of quiet cruising, and up to eight hours of zero-emission hotel mode at anchor. That last figure is the one that changes a night on board, and it is the yard's own claim rather than an inference.
One thing to be careful about, because it will confuse anyone shopping this segment: this is not the 57Steel. The 58Steel is nearly six feet longer, a foot wider, and runs an entirely different propulsion system — E-Pods where the 57Steel ran twin CAT 3512C diesels. They share a fuel capacity and not much else. If someone quotes you 57Steel figures for a 58Steel, or the reverse, that is not a rounding difference.
One hundred and ninety-one feet, 1,165 gross tons, ten guests, thirteen crew. Note the crew number against the guest number — this is a boat with a large professional complement relative to the people it carries, which is what a yacht of this class properly staffed looks like. Sanlorenzo publishes no cruise speed, no range, no draft and no displacement here either, so at this size get all four from the build specification before anything else.

Sanlorenzo publishes up to eight hours of zero-emission hotel mode at anchor, along with up to two hours of quiet cruising and an emissions reduction of around ten per cent. These come from the diesel-electric system, the first in the yard's steel line, built around twin E-Pods rated at 850 kW each. The hotel-mode figure is the one that changes life aboard, because it means lights and air conditioning overnight without machinery running.
Sanlorenzo lists thirteen crew alongside ten guests, on a hull of 191 feet 1 inch and 1,165 gross tons. That ratio — more crew than guests — is what a properly staffed yacht of this class looks like. It is also the largest single ongoing commitment of ownership, and continuity in the senior positions is worth more to the next five years of running the boat than almost anything a survey will find.
Sanlorenzo's specification block gives 11.25 metres, which is 36 feet 11 inches. Worth knowing that the descriptive copy on the same page refers to an expanded 10.8-metre beam, so the yard's own material is inconsistent on this point. We have used the specification figure. The difference is a good argument for taking beam, draft and weights from the build documents for a specific hull rather than from any website.
