The 45m motor yacht Monoposto 147 is one of the latest concepts of the Hong Kong based Granocean. Designed by the Granocean’s in-house designer Vincent Mausset and boasting naval architecture by renowned Sparkman & Stephens, the Monoposto 147 superyacht is a beautiful long range commuter capable of cruising economically well above the customary speeds of the displacement category.

To achieve this task priority was given to an optimum length to beam ratio, the most efficient hull lines and minimum cross sections allowing to keep high speeds through all sea conditions. These various options also resulted in a weight half of an equivalent length displacement yacht. Her stunning looks purely result from function and not artificial fashion features, nevertheless her long enclosed foredeck and thrown aft superstructure bring this yacht an unavoidable yet unintentional reminiscence of iconic Italian single seaters; long bonnets and aft cockpits. The explanation for this project’s name.

The large foredeck of the Granocean luxury yacht Monoposto 147 features an hydraulically retractable awning over the forward dinning area forming an integral part of the foredeck while underway, alternatively offering a sun shelter when moored or in fair weather. Located underneath, the garage is able to accommodate tenders from 5 to 5.5 meters released through side hinging doors.

LAYOUTS

Beach bar
Starting aft of the accommodations, the Granocean opted for a casual circular bar with fixed stools. Its 180 degrees window bay opens up on a sun deck gradually stepping down towards an hydraulically hinging swim platform. This low level deck allows a natural communication with the ocean and a true feel of speed while watching the wake on motion.

Dining room
Located at full beam and using its entire width, the dining room is not short of other conventional mega yacht’s size. The Granocean divided it in two tables for a total of fourteen guests, allowing two parties to dine separately, however many other options are available including distinct dining and lounge areas. On option “A” and “B” This dining room enjoys a rare feature: two “lazy boys” communicating with the galley at lower deck, one bringing up the food and one taking back the dishes. It allows quick and efficient crew service between galley and dining room while freeing the main deck from a galley. The whole deck space is therefore used for entertainment. Additionally the “lazy boys” serve in continuation the upper lounge and optionally the wheelhouse.

Study – Library
A few steps up portside and forward of the dining room, the Granocean featured a smoking room- study- library. Opening on deck through large windows it enjoys ocean views side and forward. They have experienced that cozy, more private and secluded rooms are often favored by guests over larger spaces. This is just the place for such a lounge. Enjoying an opposite head and shower on starboard and a two meters “L” settee this room will also serve as an occasional cabin for an overnight guest.

Observation Lounge
Right on the forward end of the castle, facing the route, is situated a full beam and 180 degrees observation lounge. It can welcome eight to ten guests seating on convivial arched and raised settees which combined to large tables allow a second dining area. At night this lounge will convert into a TV-Movie room featuring a big screen rising from the forward countertop. Aft and at starboard is located a bar counter with fridge and sink. It allows to close the beach bar and serve this lounge without the crew circulating with plates and drinks. An interesting feature of this lounge is its two opposite access doors on side decks offering perfect ventilation and breeze draft at all time.

Foredeck
If the 45m superyacht Monoposto 147 is different than most others in the size, it largely stems from its hydraulically raised awning covering the huge foredeck. While conventional yachts will entertain aft in full view of dock passerby’s, the Monoposto 147 will party forward, sheltered from the marina crowds. The foredeck features flush folding chairs and dining table sparing fastidious storage for the crew plus a twin Spa Pool lodged in a typical 1930 commuter style stem cockpit. This area will also feature a built-in bar, a barbecue and an open galley located against the Portuguese bridge.

Entertainment Lounge – Disco
Facing aft on the upper deck this lounge can be considered the equivalent of the rear salons of conventional yachts except that it enjoys an 180 degrees view plus, given its higher location, an uncluttered sight, freed from hull bulwarks. Equipped, with a wet bar and a large countertop forward it also benefits from the two lazy Boys so that meals can be safely delivered from the galley located two decks below. This lounge features a head on starboard. The Granocean opted to show this space with loose furniture which can be moved around to free a dancing floor which itself communicates flush with the upper aft deck.

Wheelhouse
Dedicated to navigation this command station concentrates the usual navigation devices with three captain chairs side by side. Aft of the wheelhouse a raised settee offers a second and higher observation position able to seat a minimum of eight people with large folding table usable as Chart tables or dinette. If folded down, the arrangement converts in a queen size pilot berth. A very rare feature of the Monoposto wheelhouse is its 360 degrees bay window, similar to modern tug boats and extremely friendly for all around crew watch in busy waters. The wheelhouse is surrounded forward by a large Portuguese bridge facilitating docking maneuvers.

Observation deck
Situated at the top of the vessel, above the wheelhouse, is an observation deck with a commanding 360 degree ocean view. This platform, shaped like a fly bridge but without the clutter of instruments will give the owner and his guests a privileged position to savor the experience of “flying” across the ocean. It will also be equipped with a fridge and a wet bar and can of-course double as an ideal spot for sunbathing in complete privacy.
