The yacht presented here, Happy Days, at 50 metres LOA is the biggest pleasure craft in composite ever launched in America. Merit for her construction goes to Delta Marine - based in Seattle on the banks of the river Duwamish - a very well known brand name which is considered by many to be one of the best shipyards in North America and probably the world.

Delta Marine undoubtedly owes its fame among the public at large to a series of really beautiful superyachts, but its history began in the early 60's as a builder of fast pleasure craft. Shortly afterwards it made a name for itself above all as a builder of professional fishing vessels. With those robust, reliable and easily maintained boats, built for rough seas, and with their design and construction, Delta achieved great fame and success. This in turn led to the yard's progressive growth until it reached the size of an actual shipbuilding industry. After the first successes obtained in the pleasure craft sector the Jones family, who have always been at the helm of Delta, decided in 1980 to orient production towards the luxury yacht segment, building in steel, aluminium and composite. We chose Happy Days precisely to represent this last typology of vessel. With a length of 50 metres this displacement yacht can call herself the brand flagship in composite, but also the biggest in a recently launched mini-range of four. Happy Days is not only longer but also beamier - almost zoomed up to 10.40 metres - exclusively because the owner wanted an even more spacious yacht with huge volumes. This is borne out by the nearly 700 square metres that guests can enjoy while under way. The whole is the work of the Delta Design Group, a many sided structure specially created by the yard and responsible for the exterior, the interior and also for the full displacement hull. A workgroup that operated in close contact with the owner, also with regard to the furnishings and décor which are indubitably rich in inspirations that run from early 20th century modernism to more recent Pop Art. A yacht that can take you anywhere: big, comfortable and embellished with art works and furnishings that contribute to rendering the overall effect highly personal, welcoming and luxurious. The restrained use of wood for the walls is original, while the use of glass is more extensive: there are tons of it aboard! To give some idea, over and above everything that is normally in glass aboard a yacht - splendid doors, interior stairway parapets, shower cabins, furnishing accessories and lamps created as works of art - the grand dining room on the main deck has a rectangular table (about 3.6 by 1.2 metres) consisting of five great transparent slabs, created by master glassworkers and weighing 90 kilos each. Around the table the twelve chairs are upholstered in different coloured leathers. Plus a huge wall-effect partition and furniture and doors worked with geometrical motifs. Simulated frames, also used in the cabins and actually a sophisticated lighting system, are a reference to the age of great voyages - the 1930's - and the vast "machines" that made them possible. Symbolically it's a tribute to the interiors of the Pan Am Flying Boats, comfortable, luxurious and long range, just like Happy Days, which took their guests to Latin America but also as far as Asia. References to frames and lighting are also found in the main saloon which extends aft, featuring two living areas with different furniture and upholstery which, together with the floor covering, light up the space with colour. The aft zone includes a very large cocktail area with a six seater sofa and armchairs. Though it is outdoors it can also be closed in and air conditioned.

Farther forward on the port side, the very spacious and fully equipped galley is followed by a service dinette, both well linked to the exterior and to the crew's night quarters on the lower deck which sleep 10 in 5 cabins. Farther below, Happy Days has a technical half-deck for storage. There are six guest cabins, four of them on the lower deck - two with double and two with twin beds - and the other two forward on the main deck, next to a gym and a landing that serves as a library. The furnishings and spaciousness of these two cabins give them VIP status.

The owner's cabin is on the upper deck, occupying the whole area aft. The bedroom extends the whole breadth of the beam, with nuances of colour and furnishings in Caribbean style, and the bathroom has a shower cubicle and Jacuzzi, but above all there is exclusive access to the outside deck, which can also be closed in, becoming an actual terrace for the owner. Amidships on the upper deck the classic sky lounge is accessible from the main deck also by means of the lift that links the vessel's four decks. The sky lounge looks onto two external balconies and features a piano, a bar and the umpteenth living area. Farther forward are the captain's cabin, a daytime bathroom and the wheelhouse, again with light-coloured wood contrasting with the blue of the fabric and leather that covers everything, even the command station which is chock-a-block with screens for controlling each part, each machine and each piece of apparatus on board.

The sundeck above is protected for more than half its length by a hardtop that bears the aerial mast and creates an area beneath that's well suited to parties and celebrations. Here too there's a bar and dining and living areas, but also a circular mini swimming pool, a solarium with sun-beds and the housing for a small tender and a jet-ski. The main tender is aft of the engine room, in a special submersible garage between the workshop and the control room.

Now let's look at performances: with the thrust of 2 Caterpillar 3512's that deliver 1.650 HP each, Happy Days touches 17 knots maximum speed, with a cruising speed of 14 knots. With 82.900 litre capacity fuel tanks the vessel has a range of 5.000 nautical miles at a speed of 13 knots.
