The designer’s point of view
Maurizio Cossutti explains the naval architecture of the Bavaria C46
The new C46 develops, reinterprets and expands the design and high-performance concepts at the basis of the shipyard's C-Line. Like all models in the C-Line, the C46 is the result of a collaboration between the Bavaria development team and the Cossutti Yacht Design Studio. This is the sixth model born from the collaboration between our office and Bavaria Yachts, and it is the evolution of the concepts introduced with previous models. With the C46, the chine and V- bow concepts introduced with the Bavaria C42 and C38 have been enhanced and improved from both the naval architecture and exterior design points of view. Bavaria’s request was to design a big
and comfortable 46ft boat with an elegant and sleek appearance. For this reason we evolved the two-level deck into a more classic design that allows it to be lower at the bow, satisfying the required standing heights, in particular in front of the mast. In this way the eye is able to “run free” from bow to stern without any bumps or interruptions. The sheerline is an evolution of the previous models, giving the chamfer a

workshops at Bavaria Yachts and also many discussions, which produced a clear specification for the designers, Maurizio Cossutti and Alessandro Ganz. After all, this new Bavaria should not only be fast and sail well, but also be easy to handle for a large or small crew and even for sailing singlehanded. It took a long time to fine-tune the concept and come up with the many detailed solutions that in the end completely fulfilled the design brief. One central aspect is the winch layout
of the cockpit. A maximum of six winches ensure full versatility. Two winches, one on

complex shape that changes height and inclination as it runs along the hull side, ending at the bow with an integrated bowsprit that gives the feeling of a longer and more elegant boat. Great attention has also been devoted to the transom design, which has been completely refined in comparison to the previous models to have a lighter appearance. The design is of course dictated not
just by aesthetics but also by the production requirement for a boat that is easy to produce and assemble. The hull shape shows a powerful bow, which is appreciated on the smaller models we designed for Bavaria, both for the additional volume on deck and below, and also for the good balance given when
each side at the helm stations, make it easy to sail the boat from here, where both the mainsail and headsail sheets are close to hand. However, when manoeuvring with a full crew, the space by the helm can become a little tight, so there is the option of placing an additional winch on each of the cockpit coamings in the traditional way. The headsail sheets can be redirected so that they can be operated from here as well as from the helm positions. Similarly, any of the halyards, which are all led aft to the cockpit, can be operated from any winch. And of course there is the option of

sailing heeled, but with a different, higher, chine position, and a more tapered and higher transom. We designed a sailplan that ensures the
optimumsailing performance, keeping in mind the well-known characteristics that a Bavaria customer wants fromhis boat, such as high stability and the balance of the helm. The sailplan itself is characterised by a tallermast, compared with competitors and also with the C45; the jib tracks on the coachroof allow narrower sheeting angles and a refined keel, deeper with 2.30mdraught but with a lighter, slimmer bulb, add some “sportiness” despite the C46 being clearly a bigger, although not heavier boat than its predecessor.
ordering at least two primary winches as electric winches. Themainsail is controlled by a "German
mainsheet" without a traveller: the sheet is led fromthe boomto themast and from there aft into the cockpit on both sides, where it terminates on both sides on the winches at each helmstation. However, there is also a simple variation here: if you turn the sheet around and attach the loose ends to the boom, you have an "endless sheet" in the cockpit, and a double sheeting systemwith which each side of the sheet can be adjusted individually and the boomcan be trimmed very accurately.
A large foretriangle gives ample space for a powerful self-tacking jib with a usefully tight sheeting angle
