To realize this idea, it was decided to follow a modern design process, assigning specific tasks to different specialists, among the best in their field.
Ideation and project leader
The idea and project coordination are by Pierpaolo Ballerini.
Its task is to draw up starting from the initial specifications of the boat, then move on to the identification of partners for the development of the different parts, and then follow the details given to the development of the project executive. He also attended the fluid dynamic simulations (CFD) with some specialists using the most advanced programs used in the design in the last America’s Cup campaigns.

One of the main developers of the molding technology infusion in the marine industry since 2003.
H3O study, based in Arcore.
They developed the initial forms and then the final designs of the boat.
Dimensions and calculations structures
The Studio STyacht Doug Schckler and Davide Tagliapietra, have dealt with the design and dimensioning of the keel pivot and calculation of structures throughout the boat, with the aid of FEM programs for the last generation.
Optimization sail plan
The Irish company Azure Smart specialized in advanced fluid dynamic simulations in the area of the sails, was in charge of the optimization of the sail plan.
Interior and equipment
The Technical Dept of Comar Yachts as well as realize the boat has the task of designing interiors and installations
The goal was to create a new kind of boats, a modern reinterpretation of the big cruise boats of the 80’s.
The Comet 46 EX was born to surf with comfort, safety and performance, built with quality materials and systems that can provide years of happy cruises. The attention to detail, the extreme search functionality resulting from years of sailing, and the ability to customize according to the customer’s needs, complete the design.
The study of the deck is started from a search for the features that give answers, a place for each thing.
The bow anchor can be single or double, depending on your needs, with one or two winches, the sail locker can accommodate a gennaker, and a jib system, plus a few fender.
The cleats are 2 + 2 (optional) in the bow, 2 amidships and aft 2, of adequate size and robust.
The side decks are wide. The furling and all maneuvers are external, easily accessible and tidy and in sight.
The roll bar hosts the adjustable mainsheet traveller, spray hood, bimini top, repeaters instruments (visible from the entire crew), the cockpit lights.
The top of the deckhouse hosts a photovoltaic panel (optional) and numerous hatches.
The cockpit rotates around the multifunction table, chairs, support mainsail winch, inflatable life raft, refrigerator compartment and small locker.
There will also be a large locker to the right, deep, and with inside access, a dedicated anchor locker aft (optional), and one for safety equipment (life ring and grab bag).
On the bottom of the cockpit there is a large locker for the tender (3.10 m), deflated, and accessible directly from the platform, so that you can inflate and deflate with comfort. At the same locker can accommodate a folding gangway standard.
Under the steering there are 2 rooms that can be opened to the inspection, and to be used as storage for material of little use.
At the stern there is a specific locker outboard up to 15 hp or so.
The boat ends with a simple aft, fold manually with a hoist, equipped with a ladder, broad, solid and comfortable, equipped with a handle for the climb.
As an option, you can mount a technical pole to support antennas, wind generator, radar and other equipment. In this case can be coupled with a removable davit on the starboard side that allows to lift the tender even for short voyages.
The steering wheels are oriented in a manner unusual, but very comfortable, the result of an in-depth ergonomic research, which aims to have the best view on the bow and the best accessibility to the winch. The mechanism is directly on the rudder stock, without steering cables. Between the two rudders there is a rigid bar connection, easily detachable in case of failure.
The Pilot House
The choice of configuration Pilot House has a number of advantages:
a) 360 ° visibility, with the ability to control the navigation from the inside, with the remote autopilot, joy stick (optional) and second throttle motor (optional)
b) Concentration of both fixed and variable weights amidships, motor, batteries, plumbing, boiler, generator and air conditioning (the last two optional), water and fuel tanks.
c) Protection of the cockpit from the elements.
d) Great brightness of the interior, with a wide view of the outside, which reduces the feeling of claustrophobia.
e) The careful study of ergonomics and size allows the helmsman a perfect view over the bow and sails.
The comet 46 ex have a fix bowsprit, when we can equipe a jennaker or code zero sails. the regulation is directly on the cookpit.
An attack by one staysail forestay, which can work on a self-tacking rail, immediately ahead the mast.
On the side of the deckhouse, are positioned 2 rails for genoa, adjustable from the cockpit,on the roll bar is positioned the mainsheet rail, with a T system, returned into the cockpit to the central winch and can be electric or hydraulic.
In the deck are positioned the halyard winches (2), preceded by a battery of stoppers, all halyards can easily be returned on the central winch to facilitate hoisted, when it is automated.
Farther aft two genoa winches.
All material is generously sized, calculated and positioned to reduce friction and assuring long life.
The sail plan has been optimized after extensive fluid dynamics studies conducted by Smar Azure. The goal was to create a sail plan that would allow easy handling in a wide wind range, while maintaining optimum performance. During upwind you can choose between a walled code 0 on the bowsprit for light winds, a staple for moderate winds (up to 20 knots) and a self-tacking staysail for wind strengths above. In this case there are provided flying stabilization.
The mainsail has 3 reefs and the staysail.
On optimization has been worked hard on the balance of the boat and the ability to go back to the wind with a positioning of the rails bow relatively internal.
For down wind there is a gennaker bowsprit and if needed a system of bows with twin spinnaker poles (optional).
With the use of these simulations have been obtained also expected loads on the sails and mast, allowing a more precise sizing of deck equipment and structures.
To minimize pitch and roll is provided, on request, also a carbon fiber mast.
The study of the hull has been carefully conducted with the most modern fluid dynamics analysis programs. The goal was to find a new hull shape, able to combine speed without too many compromises, on waves and stability. All in the presence of loads hugely variables, linked to the use. The displacement-load of 12 tons can be up to 16 at half load and 17 at full load.
Only by developing different hulls and simulating the performance with programs that take into account waves and interfacing accelerations so obtained with the data of comfort in navigations they arrived to the hull of your choice.
The presence of the spray rail is motivated by the need to have a dry boat, preventing splashes during the stages of support at the bow, in virtue of the sides vertical, arrive in the cockpit.
The keel is scheduled in 2 versions, one fixed and one pivoting. The pivoting keel has several advantages:
– Draft ranging from 3.5 meters to 1.6 meters
– Increased strength in the event of a collision, for the possibility of returning bending.
– Excellent hydrodynamic efficiency, due to the strong elongation
– Very high righting moment due to the low center of gravity.
In the study of the keel have sought maximum strength and durability.
The design of supports self-aligning center pin is based on the experience gained in the implementation of canting keel, with a term, without special maintenance, “eternal”. The hydraulic cylinder is in the rest position above the waterline, its maintenance (mounting and dismounting) can be done with the boat in the water.
In order to protect the keel of the boat in the event of impact, is expected hydraulic damping system that acts as a “fuse” of the system.
The hydraulic pump and the entire system uses commercial components with worldwide distribution and is very simple.
The same unit can also be used as a source of power for the central winch.
Both active and passive safety was from the outset one of the fundamental objectives of the project.
Boat with high righting moment of form and “weight” always very flat, which is easy to stand and move, both inside and outside.
Wide side decks, gunwales Well positioned, an extension of the deck to the bow, let out in a safe manner.
Most are led back to the cockpit and within easy reach of the helmsman.
The good forward visibility from the helm and inside allow you to control navigation with ease, even with bad weather.
The sail plan is easily divisible allows you to easily find a balanced configuration and suitable for all weather conditions.
The structure well sized, the realization with the use of advanced techniques such as the infusion of the planking of the hull along with the reinforcement structures (floor timbers and longitudinal), the use of adequate reinforcements in carbon, the main bulkheads composite in blanket provides rigidity and strength to the whole test.
The boat is equipped as standard with crash box in the bow, which allows it to survive severe impacts in the bow area, there is also a strip of Kevlar fabric in addition up to 30 cm above the waterline. This ensures an exceptionally robust to shocks with any submerged bodies.
The bulkheads fore and aft are really watertight, with watertight bulkhead pass-throght for all plants.
The main bulkhead that separates the cabin from the saloon can be provided on request, with a watertight door.
The pivoting keel, (optional) as already mentioned is a further element of safety for its ability to absorb major shocks.
Construction is scheduled on female molds, with fabrics of glass or glass / carbon, impregnated with vinyl ester resin by the method of infusion. In a single operation are made even the floor timbers and longitudinal, creating a homogeneous single body.
In the areas of greatest stress are provided extensive carbon reinforcement.
The main bulkheads will be realized in composite infusion, with enormous advantages in terms of rigidity and robustness. The same bulkheads are laminated to the deck.
At the bow there is a sacrificial area, the crash box, while the bottom shows at the outside up to 30 cm above the waterline in a layer of fiberglass and Kevlar for maximum impact resistance.
The deck shall be laminated to the hull in the most stressed areas.
The entire plant will be “over standard”, with great attention to the accessibility of the components and spaces for maintenance operations.
