Tankoa S501 Motor Yacht

Three propulsion modes sit behind the Tankoa S501: a diesel-electric setting where two generators feed her electric motors, a hybrid split where one engine shaft powers a second motor, and a booster mode where both main engines and generators combine for full power. Tankoa Yachts will deliver her in 2026 as a stock fifty-metre displacement yacht in Italy, built to be efficient at low speed and capable when more is needed.

Build and provenance

The S501 is a monohull displacement design from Tankoa Yachts, delivered new for 2026 rather than converted from an older hull. At fifty metres and 499 gross tonnes, with a beam of nine point four metres and a draught of two point four metres.

Layout and accommodation

She carries twelve guests across six cabins; a crew of seven lives and works separately to run the yacht. Glass bulwarks and fold-out balconies open the interior to the water at anchor, letting the layout switch between an open room and a private one at a guest's choice.

Performance and engineering

Two MTU 8V400054 engines produce 1,215 hp, 895 kilowatts, apiece, giving her a cruising speed of fourteen knots and a top speed of seventeen. Two variable-speed generators can run her electric motors alone for the quietest setting, one engine shaft can generate power for a second motor in a hybrid split, or both engines and generators can combine when full power is wanted. A generator is fitted as standard, sized to keep her systems running through any of the three modes.

Where she lies and how to see her

The Tankoa S501 lies in Italy. Boatcrowd arranges her viewings and is there for each one, and once a buyer's offer is accepted we schedule the survey and sea trial that follow.
