Integrity Motor Yachts 490 Grand Sedan. Inspired by owner feedback, the Grand Sedan offers more refinement and a touch more performance for those looking for just a little bit extra in their motor yacht. A fantastically spacious interior saloon and helm layout adjoins the customary entertainers galley and rear deck, with a new accommodation layout offering a stately walk-around bed, with the forward guest cabin is available in different layout options. The standard engine and streamlined hull design means the 490GS will easily achieve 15 knots. The 490 Grand Sedan, another grand idea from Australia’s leading displacement motor yacht brand.
