ISA Yachts announced the delivery of the 66m Granturismo now christened OKTO.

OKTO has a black metallic steel hull and silver metallic aluminum superstructure, she is powered by twin CATERPILLAR 3512 C engines rated at 1765 KW @ 1800. She can reach a top speed of 18,5 knots and at a cruising speed of 16,5 knots, in maximum comfort.

ISA Yachts CEO, Luciano Bregola, says

“This gem of a yacht is the result of the perfect collaboration of a well-concerted team of experts who designed, engineered, built and delivered a distinctive yacht which will set new standards in the industry. We are all extremely proud of OKTO – Bregola continues – and wish her Owners to enjoy extensive world travels aboard such a magnificent yacht”.

The concept behind the ISA 66M (the largest yacht by ISA Yachts to date) is to emphasize the outdoor experience of a yacht without compromising the space and comfort that the owner would expect from a steel and aluminum displacement yacht. The overall beauty of yachts over the years has been lost to interior space, on the contrary Granturismo is a concept that allows space for owners who love the sea and like to be outside.

The ISA 66M GRANTURISMO is a custom 4-deck yacht with an aluminum superstructure and an impressive steel hull with a straight bow. The yacht is designed by Andrea Vallicelli and the interior by Alberto Pinto. Both designers worked in very close cooperation with the yard and the Owner’s management team to combine both design and architectural aspects based on a strong contrast between the harmonious and curvaceous lines of the decks with the rigorous and diamond-like geometry of the transom and sundeck. The hull shape and bow are optimized for both efficiency and comfort.

Okto is a custom motor yacht with lots of space in relation to the total volume and her lines are sleek and graceful. The design does not achieve extra deck space by stacking the decks, there is not the piled-up effect – one layer after the other, the philosophy of the whole concept is to guarantee the owners space and comfort they would expect. This stylish interior has been subcontracted to the renowned Austrian company List General Contractor GmbH.
The naval architecture is developed in-house by ISA Technical Department in conjunction with BMT NIGEL GEE naval architects, including a comprehensive four-month cooperation with MARIN (Maritime Research Institute Netherlands) including a very intense tank testing program to evaluate all possible sea-conditions before starting the production of this very first innovative 66m l.o.a. Throughout this procedure, at various steps, a close supervision was maintained by the Owner’s team.
