Greywolf 40m Explorer Yacht Design Project

GREYWOLF
Greywolf, Politecnico di Milano Master in Yacht design project, is a 40-meter explorer yacht concept designed for owners who want to travel with no limit in their destination and activities onboard.

IDEA SKETCHES
 - Research in proportion and main volume
-Tall bow to fight against rough seas
-Touch&go helipad located aft


EXTERIOR
Tall bow and a diagonal chine protect the guests from big waves when cruising rough sea environment. Touch & go helipad is located aft to transport passengers in case of emergency. An anchor pocket is integrated with icebreaker to navigate through polar seas. These features to make it explorable are harmonised in stylish fashion.

SUNDECK
 The top deck maximises the pleasure of being in an open-air with panoramic view from the top. 3 entertainment features are welcoming the guests. A jacuzzi is set forward surrounded by a circular sun bed. It offers an unobstructed view of horizon and lets in a mild sea breeze thanks to a handrail protected once again with clear glass. The deck continues with a bar and an outdoor cinema. Towards aft, a projector screen slides up and down from the t top. A retractable sunroof controls the sunlight exposure.

UPPER DECK
Upper deck serves as a control tower of the vessel and a living space dedicated to the owner. It offers a master's stateroom, a wheelhouse and a captain's cabin. Size and privacy are mainly considered for designing the owner's space. Full beam interior allows a generous 86m² of space solely for the owner. Thanks to perfectly ensured privacy by separating the space from guest / crew area, it can be arranged as a doorless space. This creates even greater sensation of openness. Plus 34m² of a large aft terrace allows the owner to enjoy outdoor space with privacy. Whereas conventional explorer yachts install the windshield vertically or in reverse direction, the windshield of the this yacht is inclined downwards to introduce more style, adding the sleekness to the profile. An overhang on top of the windshield cope with glare from sunlight.

MAINDECK
Main deck is composed of a very large exterior space in the aft
and a social living area. From the stern to the aft cockpit is stretched to nearly half the length of the yacht for various outdoor activities. Touch & go helipad has 51m² of space, which can afford Eurocopter's EC135, 10m model of its length. Besides its main use, the helipad can be used for loading tenders and jet skis and also for sunbathing. Heading forward, a pair of jacuzzi and a central lounge sofa offers extra options to enjoy the sun. With al fresco dining table, the deck then welcomes the guests inside with unique central column. Two TV screens are built in the column facing both inside and outside, which allows the luxury to enjoy a movie from the aft sunbathing area. The main saloon is decorated with modern and luxurious touch. The galley is arranged close to main saloon to serve meals in no time.

LOWER DECK
Lower deck is arranged with beach club and ample accommodation for guests and crews. The beach club allows seamless access to sea. It provides extra openness and also protection by having its door built with tinted glass. The guest area has 2 VIP double and 2 twin cabins for 8 guests. The crew mess is located forward and includes 3 double cabins for 6 crews. Aft to the engine room locates an extra storage space to store water toys.
