R.B. DERELI YACHTS MUMU

The sloop MuMu was designed by the famous naval architect Philippe Briand who, in line with the philosophy he applied to several other models signed by him, created a sailing boat that satisfies her Owner's requirements who wanted a high performance boat but also an elegant and comfortable yacht. Obviously, in order to meet both demands it was necessary to have an adequate length at the waterline as well as a powerful sail plan - supported by mast and rigging, by the hull size and by materials capable of offering the most favorable mechanical resistance to weight ratio. Nevertheless, this is not enough to obtain a true Lady of the Sea: a basic emotional component, expressed through what may be appreciated by the senses independent of the technological contents, is also needed. Last but not least, technology and the way it is used in favor of performance must satisfy the expectations of whoever, Owner or guest, wishes something more from a superyacht.

In the case of sailing yachts, in particular, light and high-resistant materials help the designer in creating elegant interiors, with finishing touches similar to those of an apartment and decoration elements generally non-existent on racing yachts. This is why the recent trend has been the production of racers/cruisers, that is, of sailing boats capable of offering cozy interiors like large cruisers yet with high performances like the fastest racers. Philippe Briand, a true expert in this field, chose composite materials for hull, deck and superstructures and used construction techniques aiming at reducing weight at all costs, keeping in mind that deck and superstructures are subject to different strains than the hull. MuMu was built in Turkey, in the R.B. Dereli Yachts yard specialized in the shipbuilding of custom and semi-custom yachts of all sizes, in particular of superyachts. Today, MuMu is one of the fastest sailing yachts of this size crossing the oceans and, if we consider her original and charming appeal, we realize that we are talking about a vessel worthy of being considered one the most important modern sailing boats. The sloop includes a staysail, to be fitted on the babystay, a masthead jib and a full-batten mainsail. Notwithstanding her imposing sail plan - the mast is 47.24 meters high and the total sail area is 603.86 square meters - she was designed to be maneuvered by a small crew. The standing rigging includes four sets of swept spreaders, running backstays, and twin standing backstays. MuMu was built in compliance with the American Bureau of Shipping +A1 Sailing Yacht standards. As for the emotional component mentioned earlier, layout and interiors were styled by Eva Cadio. The designer, together with the Owner, chose a modern style, with essential shapes and chromatic combinations and used bright and dark tones to bring out and lighten up inner spaces on the basis of the perceivable needs she wanted to highlight. The designer's work resulted in airy and sober areas, where light plays an essential role for perceiving shapes. She used symmetrical lighting panels, spotlights to highlight some decor elements and to increase depth of field and a diffused lighting to soften the perception of the surroundings. In the lower deck there are four cabins for the Owner and his guests. The full-width master stateroom is aft and includes vanity, sofa, desk, two bathrooms sharing the same shower stall and two large hanging lockers; access is through the corridor that connects the master stateroom to a guest double stateroom and a twin cabin, both with en suite bathrooms. At the other end of the corridor there is the amidships saloon. Here the extraordinary headroom and lighting obtained by the trunk and its windows - not imposing on the outside yet very spacious inside - is worthy of a mention. Actually, there are two saloons. This one has a C-shaped sofa and three coffee tables opposite the inner wheelhouse, which includes a large chart table and the instrument control panel of all onboard plants. The other one is forward, to starboard, with a large plasma screen separating the living area from the dining room opposite. Forward and to port, along the corridor leading to the crew quarters, there is another double stateroom with en suite bathroom. The bow area, except for this cabin, is to the exclusive use of the crew and includes two twin cabins with Pullman beds and a double cabin for the captain - all with en suite bathrooms -, the crew dinette, the galley, service areas and storeroom. Even the deck layout conveys through its shapes and technical solutions the double vocation of MuMu: a relatively easy-to-handle racer and a cruiser with open-air spaces essential for relaxation and comfort. Aft, the transom can be mechanically opened so as to become a sort of private beach with direct access from the cockpit. Proceeding forward there are two open-air wheel stations embedded in a structure which also supports two big electrical winches aft, then there is the open-air saloon with two comfortable C-shaped sofas, one facing the other. Forward of this area a passage allows easy access amidships on deck. Then there is the trunk, which in its aft and outside part includes two fore- and-aft sofas. A mobile top and the boom cover this area up to the two aft steering wheels. Forward of the mast a recess in the trunk houses the tender, some safety equipment on its sides and a self- inflatable. This equipment is stored and hidden in such a way as to keep the deck tidy. As for performances, MuMu reaches 15-16 knots when sailing in a moderate breeze and 12 knots when propelled by the 550-hp 3406E Diesel Caterpillar engine.
