Specifications
Sanlorenzo 1740 timeless flybridge with space
The 1990 Sanlorenzo 1740 is a classically styled 17.40-metre motor yacht that invites long days at sea and relaxed evenings on board. She is built in GRP (polyester) with a V-hull, giving her a distinctive profile and a solid foundation for comfortable cruising. With a 5.00-metre beam, she offers notably generous living space both inside and out. This Sanlorenzo has been used on the seas and even as a liveaboard, which says a lot about her volume and practical layout. For anyone looking for a Sanlorenzo motor yacht of around 57 feet with potential for cruising, extended stays on board, or a charter project, this is an interesting starting point within the BoatAuction offering.
Inside you’ll find accommodation geared towards longer stays. She features air conditioning, hot water, a shower, and a dinette that makes life on board pleasant—also when you’re not just planning a day trip but truly want to stay. The galley includes, among other things, a cooker, oven, microwave, refrigerator and freezer, making the boat suitable for families, guests, or stays with multiple people. With eight fixed berths, this flybridge motorboat is also attractive for those looking for a spacious motor yacht to cruise with friends or family, or to use as a floating holiday home.
Sanlorenzo 1740 now in the online auction. Anyone can bid up to and including 24 August 2026.
How does this Sanlorenzo 1740 perform at sea?
She is equipped with two inboard diesel engines, Gambia 8V92, each with eight cylinders and electric start. The stated engine hours are around 1,700 hours. Cruising speed is approximately 12 km/h and maximum speed approximately 20 km/h. On board there are instruments such as a tachometer, temperature gauge, oil pressure gauge and fuel gauge, helping you keep a clear overview while underway. Thanks to her V-hull and twin rudders, this type of motor yacht is designed with course stability and control in mind, suitable for use on open water.
Is she suitable for living aboard or longer journeys?
Yes, her equipment and layout are well suited to that. The combination of air conditioning, hot water, shower and a complete galley setup makes life on board more comfortable than on many motorboats in this length class. The number of fixed berths—eight in total—also indicates a layout intended for longer stays on board with several people. Those looking for a motor yacht to live on, a liveaboard boat, or a spacious yacht with lots of interior volume will find in this Sanlorenzo 1740 a model known for her generous design.
What is known about maintenance and condition?
According to the information provided, the boat is in reasonable condition. She was last taken out of the water for maintenance in 2025, and antifouling was applied in the same year. No indications of osmosis have been reported. The teak deck is described as being in good condition and the hull as sound. It is also stated that she has been sailed recently, which indicates that general operation has been checked in practice. An onboard battery charger is present, and it is indicated that the batteries have recently been replaced, which is convenient for daily use and living aboard.
Are there any known points of attention I should take into account?
Yes, one known point of attention has been reported: a defect in the starboard gearbox control lever. For a buyer, this is relevant information to include in preparation—for example during viewing, technical inspection and estimating any work after purchase. Beyond this, no list of other defects has been provided, but as with any used motor yacht from 1990, it is wise to assess her systems, propulsion and installations carefully.
Outside, she offers pleasant amenities for time on the water. Think of a teak deck, guardrails, a swim platform and swim ladder for comfortable anchoring and swimming. The boat has one anchor with chain and a hydraulic windlass, making anchoring practical. Davits are present, useful for lifting equipment. Exterior cushions make the deck an attractive living space, especially during long summer days.
This Sanlorenzo 1740 combines the look of an Italian motor yacht with the space you want in the 17-metre class. She is interesting for buyers looking for a flybridge motor yacht, a Sanlorenzo 57-footer, a GRP motor yacht with twin diesel engines, or a boat with eight berths for cruising and staying aboard. Through BoatAuction she is given a platform for enthusiasts who see her potential and would like to further tailor her to their own wishes.
