Sanlorenzo SD90: The Thinking Owner's 90-Footer
The SD90 is a navette in the proper sense: a semi-displacement 90-footer with two engine options, published at 14 knots and 17 knots, built …

An icon of voyaging
If your plan involves weeks aboard rather than weekends, the SD line is Sanlorenzo's answer. The yard describes it as inspired by the transatlantic liners of the 1930s: composite yachts from 28 to 40 metres, each with exceptional range and comfort, designed to carry you toward the most distant horizons.
These are semi-displacement hulls, which is the engineering that makes long stays practical. They are not fast — the range tops out at 17 knots — but they carry serious tankage for their length and they are drawn by Zuccon International Project, whose exteriors have aged better than most.
Sanlorenzo builds four SD models — the SD90, SD96, SD118 and SD132. We have reviewed three of them, from 90 to 133 feet.
The SD Lineup, Smallest to Largest

A semi-displacement navette drawn by Zuccon International Project, offered with MAN i6 or V8 power for a published 14 or 17 knots, carrying 13,000 litres of fuel.
Ninety-five feet carrying 15,700 litres of fuel and 2,500 of water — unusually large tankage for the length, with twin MAN 8V 1,300s for a published 17 knots.
420 gross tons in 133'6", with Sanlorenzo's asymmetry concept carried across two decks and a 70 square metre reconfigurable beach area with opening terraces.

Moving Up the SD Series
SD90 — 90'0", 8 guests / 4 crew. The navette proper. Two engine options with a published speed for each: MAN i6 at 800 HP for 14 knots, or MAN V8 at 1,200 HP for 17.
SD96 — 94'11", 17 knots, 8 guests / 5 crew. Twin MAN 8V 1,300s, and 15,700 litres of fuel — a large tank for the length, which is the point of the hull form.
SD132 — 133'6", 17 knots, 10 guests / 8 crew. 420 gross tons, the asymmetry concept across two decks, and a 70 square metre reconfigurable beach area with opening terraces.
The SD90 and SD96 are close enough in size that the choice is really about crew and tankage. The SD132 is a different proposition entirely: nearly forty feet longer, eight crew, and the only one of the three where Sanlorenzo publishes a gross tonnage figure.
Our Take
The SD line is the part of the Sanlorenzo range I find easiest to recommend, because it is honest about what it is. Nobody is pretending a 17-knot semi-displacement boat is exciting. It is comfortable, it carries a lot of fuel and water for its length, and it is pleasant to be on for a month. That is a real product and plenty of builders fail to deliver it.
The SD90's engine choice is the decision I would spend the most time on. Sanlorenzo publishes 14 knots with the MAN i6s and 17 with the V8s, which is an unusually clear way to present an option. Most owners of a boat like this are well served by the smaller pair; you take the V8s if you genuinely need to hold a schedule or make a weather window.
The frustration with this line is the same as everywhere at Sanlorenzo: no published range. On a range of boats sold on the idea of going a long way, that is the figure you most want and the one nobody will stand behind. The tankage is published, so take observed consumption from a sea trial, divide, keep a proper reserve, and you will have a number that is yours.

Frequently Asked Questions
What makes the Sanlorenzo SD line different from the SX?
The SD line is semi-displacement and built for distance and comfort rather than water access. Sanlorenzo describes it as inspired by the transatlantic liners of the 1930s: composite yachts from 28 to 40 metres with exceptional range and comfort. Top speeds are lower — 14 to 17 knots across the reviewed models against 23 to 24 for the SX — and tankage is proportionally larger. The SX, by contrast, is a crossover built around pod propulsion and beach-level living.
How far can a Sanlorenzo SD cruise?
Sanlorenzo does not publish a range figure for any model in the SD line, or anywhere else in its fleet. What it does publish is tank capacity: 13,000 litres on the SD90, 15,700 on the SD96 and 42,000 on the SD132. To get a range you can rely on, take observed fuel consumption from the sea trial report at the speed you intend to hold, divide the published capacity by it and keep a serious reserve. That produces a figure whose origin you can name, which no published estimate does.
