OSO 90 Power Catamaran (New) Description

The 27.5m OSO 90 POWER CATAMARAN is a custom-built project multihull motor yacht for sale with twin prop IPS® drives and in course of completion by the Catamar Shipyard in Rome, Italy.

Project OSO 90 POWER CATAMARAN is 90% in her building process and scheduled to be finished within 6 months from firm order. The vessel is being built for either private or charter use.

This large motor catamaran offers expansive volume, sprawling deck space, and extreme storage capacity, thanks to her amazing beam reaching almost 12m (39′), but outstanding feature is that she can be registered under 24 metres load line length.

As a result of her remarkably large dimensions, sleek design, and very low bridge clearance, this catamaran features extreme stability. Initially splashed end of July 2022, her sea trials have been successfully completed in August.

Every detail of her unique design has been carefully considered to enhance passenger comfort, including abundant exterior/interior social spaces and amenities and a versatile 5 en-suite cabin layout that can accommodate up to 10 guests in luxury and style. Further accommodation is provided for 4 crew.

Powered by twin Volvo IPS 500 drives, the OSO 90 Power Catamaran reaches, with high manoeuvrability, a maximum speed of 21 knots, while comfortably cruising at 16 knots. At her economical speed of 10.5 knots, she currently offers a 1100 nautical mile range, and it is still possible to add two extra fuel tanks for transatlantic range.

A thorough technical survey and appraisal carried out in August 2022 can be made available (in Italian language). The state of progress of the works at the time of the appraisal was approximately 90% and this makes the evaluation extremely reliable and precise. The valuation is performed with reference to current market prices since, as specified, the MY is under construction.

More details, sea-trial videos and building status photos to be provided on request.
