The New Grainger Sensori 54 MS (Master Suite) Series Raises the Bar for Style, Performance and Features in Power Cats

The Sensori MS Series brings greater breadth and diversity to the current Sensori Range. The same focus on a low displacement to length ratio for efficiency and range, the same V bottom hulls for sea kindly motion, contemporary styling in keeping with our existing Sensori cats, and a host of features that will make Sensori MS stand out from the crowd at sea or in port.

So, what’s new? While the existing Sensori range has all the sleeping accommodation in the hulls, Sensori MS features a generously proportioned master suite forward on the wing deck with easy access to a private en-suite in one hull and a walk-in wardrobe in the other. There are guest cabins amidships with private en-suites and for the charter version there is ample space forward for a crew cabin. The forward cabin in the charter version can be split into two cabins each with an en-suite or kept as a single spacious owner’s cabin.

There is also a Sports version with a more modest flybridge and an Expedition version optimized for a low center of gravity, minimum windage and maximum unshaded roof deck for solar panels.

While the earlier designs in the Sensori range have the helm station in the saloon as a standard arrangement, the MS series features the helm and navigation on the flybridge for the charter model, and an option of helm up or down (or both) on the Sports version. For the Exp. model the helm is in the saloon. The roof features a low coaming and the roof top deck can be accessed for lounging and viewing if not completely covered with solar panels.

The Sensori MS54 Exp (Expedition) will eat up the miles without gouging on the energy reserves due to a trim profile with no flybridge and low center of gravity. She will deliver a comfortable ride, economy and maximum range.

The Charter and Sports models both sport a large sunbed area on the foredeck, and the option of a set of steps up to the flybridge deck as well as the primary steps from the cockpit. The Expedition model will still offer the sunbed lounge as an option but otherwise, the focus is on lightweight and a streamlined wind profile. All the designs in the Sensori series can be adapted to new technologies including hybrid electric power systems as they become more cost-effective.

The model in the image above is the charter version with an extended flybridge deck for maximum passenger space. As well as the accommodation spaces in the saloon there is deck space and seating in the cockpit, on the flybridge deck, and in a generously proportioned sun lounge arrangement on the foredeck.

These are the layout drawings for the MS54 Charter version. They were produced in March 2021 in conjunction with Powerplay Catamarans who were considering putting our design into production but have since decided to go ahead with their own design. Since these drawings were done, we have completely redesigned the foredeck area, raising the deck height at the sides to provide better access to the bathroom and walk-in robe in the forward cabin. This has significantly improved the feeling of space in the cabin and allowed us to raise the floor height in the bathroom. The bathroom is now just two steps below the height of the sleeping cabin and has a lot more floor space.


Variations on the 54 will be coming to the website soon and there will be other sizes in the series available later in 2021.
