She is a fast offshore cruising boat.
We designed her as we would have done for our personal use in family
This 50' is designed implementing all
the advanced technologies of the moment
( prepeg carbon hull, mast, keel, carbon boom, nomex honey comb
fittings) and her design is based on our experiences on offshore
racing boats, specially the open boats,
out of rating, out of prejudice, to carry out an easy,
safe and practical boat.
are particularly studied not to get tired.
A well-balanced hull, rather
thin forward, gives a good speed in all angles.
ADP 50 is 15 to 30 % faster than
an equivalent cruising boat.
She is a light boat, easy to control.
The water ballast allows to
vary the weight : lightness while reaching, smooth movements in
The deck is very clear, very Mediterranean.
There is a comfortable aft cabin for crew
life. 3 cabins and 3 toilets provide the intimacy in
Sailing the boat
The boat is stable.
This stability is obtained by the wide
hull shape, a deep keel and
the water ballast.
This stability makes the boat very safe,
the number of manoeuvres is reduced, the boat sails only
slightly heeled and the handling is safer.
The relatively symmetric hull shape is studied to
have a good stability under sail.
This balance under heel gives the boat the capability to follow
a straight course , even under auto-pilot.
Everything is done so that the boat has a light weight. It provides
speed and easier handling.
The lifting keel is optional.
The draft of 3,20m is reduced to 1,70m with one hydraulic jack for
lifting and two jacks for securing.
The rigging is a CWING
© rigging, i.e. a carbon wing mast held by two shrouds and
one forestay. The mast is built in two parts, the forward part for
halyards and the aft part for watertightness.
is obtained by: ∑
- A carefull prepeg construction , sandwich in the upper parts
and the deck, monolithic in the bottom ∑
- A carbon mast ∑
- A mixed laminate / lead ballast with a carbon laminated fin
cooked in autoclave and a lead bulb ∑
- A good organization of the construction ∑
But especially, by keeping on the boat only what is important.
The architect has always in mind this sobriety,
this search for essential. It
is at this price only that we obtain an easy boat to sail, to manage,
- a full batten main sail,
- a jib on furling system,
- an asymmetric spinnaker on boowsprit,
- a gennaker on furler
Sailing operations can be executed from
the cockpit. Halyards, reefs, spinnaker sheets are all
brought back to the companionway, within reach. The main sail and
jib sheets are in the aft of the cockpit or in the companionway.
An automatic Magic
Trim tacking system for the main sail and the jib is optional
The boat has two steering wheels.
The cockpit sets wider to give comfortable area for the helmsman.
You sit on the corming, you rest your feet comfortably on the flange
at the bottom of the cockpit. Seats and back seats can be attached
to the corming.
The cockpit is wide with a
double central removable table. The skirt is easily accessible.
Crew members can stay in the cockpit, in the aft or in the companionway,
the invited guests can stay in the cockpit or lie on the gangways,
the bow area or the skirt.
The skirt provide space for a semi-rigid
dinghy, that one can launch with the boom, the dinghy
is protected by a rocking lid . A bath ladder can serve as a gangway,
it is hidden under the aft beam.
The common sails manúuvres are located at the aft.
Reefing is located above the companionway.
The presented solution consists of :
- 3 electric winches in the back
- 1 to 3 electric winches in the companionway
This system can be optimized :
- The main sail with 2 Magic Tream jacks
- The genoa with self contained winches so that sails are not
handled physically but through a button or a Magic Trim.
The jib is on an electric or hydraulic furling system.
We also suggest to have completely automatic reefing system on hydraulic
jack inside the mast. For safety reasons, it can be manually overriden.
The hull and the deck are built out of monolitic
carbon and Nomex sandwich . They are reinforced by longitudinale
stringers and transversal frames and bulkheads.
There are two rudders.
The keel fin is built out of laminated carbon cooked
in autoclave. The lead bulb is directly fixed between 2 frames and
The boat was conceived to be simple
to build, simple to maintain.
The whole equipment of the boat is grouped under
the central storage unit
- - Engine
- - Pumps ( water ballast, bilge pump,running water)
- - Hydrolic power source. The storage case rocks back to give
The circuits, (cold water,
warm water, diesel oil) have their defined places, and can
be easly visited in a channel which runs from bow to
In the same way, the majority of the electric wiring runs just under
the deck, and the control panel is located in the ceiling over the
In this way all the equipment is easily
controlled, quickly disconnected and interchangeable.
There are large, simple volumes. ∑
- A peak at the bow ∑
- Two or three cabins ∑
- A crew cabin, a kitchen, a navigator corner. ∑
We propose two fittings plans for the bow cabin
