The project

This first creation of Kelly Yachts was awarded by the MYDA-(Millennium Yacht Design), as the best new construction in the 10 Mt. Sail category.

This project is dedicated to sportive clients, who appreciate the dynamic quality of the yacht, but also to those who require comfort and practicality during cruising.

K33 is one of the few 10 Mt. Boats, offering three double cabins, and a head of full height, located in the center of the yacht. This solution optimizes the interior space, and permits use of the WC even during severe heel conditions. Beyond these special solutions, which usually can be found only on larger yachts, K33 does not require registration or a navigation license.

K33 has been created with dedication to research in designing, and attention to the highest quality of construction in order to offer the most competitive boat of this category on the market.


The shape of the hull is one of the most important aspects of the construction of a yacht. There are two ways to design a hull; one is to start with the interior layout, and the design “around” the cabins the hull shape, the other is to start designing the hull shape, and afterwards optimizing the interior layout, in order to optimize the maximum comfort. K33 has been designed with the second method. In fact the small beam, and straight, but never forced hull lines, permits a minimal wetted surface and fairing shape.
These characteristics guarantee symmetrical hull lines at heeling conditions, consequently excellent performance in sailing up wind without continuous helm corrections.

The hull is built in sandwich with carbon-fiberglass laminated with vinyl-epoxy resin. The lamination is manual, with following treatment vacuum consolidated in three phases: external skin, core, internal skin, and the post cured.
The core is CORE-CELL, a linear structural foam, vacuum bagged to obtain maximum bonding.
The lamination of the keel box, lower rudder bearing, and near the engine sail drive is single skin.

The position and dimension of hull beams are designed to obtain the best compromise between weight and stiffness; the bulkheads and cabinets are also included in the hull/deck structure.
Particular care has been given to the shrouds chain plates, which are bolted on deck, and two beams on the hull guarantee an optimum dissipation of loads.
The hull/deck joint is obtained through structural bondage and extra fiberglass lamination.


The deck is built in sandwich, with carbon-fiberglass laminated with vinyl-epoxy resin.
The lamination is manual with following treatment vacuum consolidated in three phases: external sin, core, internal sin, and the post cured.
The core is CORE-CELL, a linear structural foam, vacuum bagged to obtain maximum bonding.

Simplicity and easy access to all the maneuvers are the winning aspects on deck.
The particular cockpit geometry, with open transom, wide benches, and main traveler behind the tiller, guarantee comfortable space for 6 people.

The companionway is on the starboard side; with this solution, the halyards run straight through a central tunnel, directly to the single winches found in the middle of the cockpit, therefore avoiding interference between who is working with the halyards and those working with sheets.

In the cockpit there are three after peaks, providing available space for fenders and safety equipment.
The anchor locker, with the windlass that works under deck, is in the bow.
All of the hinges and locks are in stainless steel and flush, thus avoiding any interference with sheets.
K33 is the perfect mixture of elegance and sport due to the teak wash-board, tapered stanchion and open push pit.


The particular layout is surely one of the aspects that distinguish K33 from other yachts.
Great consideration was given to the designing of the interior layout in order to create a comfortable living space.
The head, in the middle of the yacht, not only permits the use of the WC even during severe heeling conditions, but also optimizes the space under deck. In fact, there are two aft cabins with double beds.
With a height under deck of 1, 87, the light colors of the dinette provide the sensation of space and comfort.
In the dinette there are two sofas, with underneath storage space, and a central stainless steel handrail (with internal passage of electrical cabling) which is also a table support. Two hatches, lockers, shelves, and halogen ceiling light complete this area.
The chart table, electric panel, and navigation instruments are located on the right side of the companionway.
The galley consists of 3 burners with an oscillating oven, a sink and pressure water tap, stowage under the sink, lockers, and a 75lt. fridge.

In the forward cabin there is a double bed, 2 shelves, 1 locker, 6 drawers, 2 reading lights plus 1 halogen ceiling light, and 1 hatch.


The K33 sail plane is designed to guarantee optimum performance sailing in either up or down wind, especially in moderate breeze conditions.
The aluminum mast ( carbon optional ), which passes through the deck, has 2 aerodynamic spreaders, with 20 deg, an aluminum (carbon optional) boom, vertical and diagonal tie rod shrouds, and a splinted backstay.


K33 appendages are studied to guarantee an optimum balance between the aerodynamic and hydrodynamic forces, without compromise.
The primary objective was to create a safe and performing boat, this was possible by an accentuated length of the appendages, and the choice of the best profile
The fin keel is stainless steel, the ballast is provided by a plumb bulb with 3% of antimony, which is the best way to concentrate the ballast in the lowest possible position, and consequently the best righting moment.
The rudder is designed to obtain the best directionality and the least resistance possible.
