Preface
This manual has been conceived by Cantiere Del Pardo to provide the owner of the Grand
Soleil 50’ with an instrument that allows him to perfectly know his yacht and then better appreciate
its qualities, exploiting entirely its technical power.
Obviously, this manual cannot replace the fundamental knowledge and sophisticated
seamanship required to sail and keep in perfect working order a yacht of the same class as the
Grand Soleil 50’.
It goes without saying that the user of such a yacht as the Grand Soleil 50’ should have
gained the necessary experience, which a manual can neither substitute nor complete.
We strongly recommend the user to follow very carefully all advices and warnings provided
by the Builder in this manual, so as to be able to take full advantage of the yacht’s performance, in
full safety.
The Grand Soleil 50’ is a yacht built first of all with the aim to guarantee the best possible
performances while sailing. It is the result of a great effort made by Cantiere del Pardo to build an
extremely pleasant and comfortable boat, selecting very carefully the most qualified systems and
equipment, to obtain a very innovative product.
In addition to all technical data provided by the yacht’s manual, we recommend you to
read carefully all attached manufacturers’ manuals and booklets about the various
components and equipment installed on the yacht. Therefore, please consult all available
information provided for a correct use and maintenance of the various systems and components.
This manual includes information and advices about most of the equipment that can be
installed on the boat, regardless of whether it is standard or optional. Therefore, only the list in
force at the moment when you buy the yacht will tell which equipment or components are
standard and which ones are optional.
Cantiere del Pardo reserves the right to modify or change the type and position of any
equipment, accessories and design described in this manual, completely at its discretion.
We recommend the user not to take anything for granted, but to always consult this manual
before carrying out any intervention which is not routine boat steering or maintenance.
We remind the user that the yacht is delivered with the optimal structures and in the optimal
conditions for people and things safety. All modifications must be carefully studied and calculated
in order not to jeopardize the yacht’s integrity. Cantiere Del Pardo

Notes on environmental pollution and accident prevention regulations
The following brief summary of the current EC regulations on environmental pollution and accident
prevention is valid only if the boat is used for private use without crew officially employed on
board.
These regulations derive from the International Convention for the safety of life at sea signed at
London on the 1st of February 1974, and following revisions and modifications.
Environmental pollution and waste disposal
The environmental pollution is divided into three main categories:
Water
Air
Soil
•Oil-free and black waters (those containing only human organic wastes) can be discharged
in open sea. Within costal area they should be kept in suitable tanks and then discharged
either in open sea or through adequate fixed emptying systems available on the quay or by
trucks for sewage draining.
•The regulations on the air pollution produced by a boat essentially prohibit the use of spray
cans containing C.F.C. gas and limit the external noises that, at a distance of 5 m from the
perimeter of the boat, should not exceed 65 dB (a) (decibels) from 6h to 22h and 55 dB (a)
from 22h to 6h.
•The soil pollution concerns the wastes discharged on land.
The EC regulation n. 91/689 concerning pleasure boats provides as follows:
•While sailing, it is forbidden to discharge into the sea any kind of non-biodegradable
products, both foodstuffs and commercial products.
•Within costal area “normal wastes” are considered the same as “urban wastes” and
therefore can be kept in hermetic plastic bags and then thrown into the trash bins.
•The “special wastes” must be placed into suitable containers or, if not available, given to the
local collectors in conformity with the current regulations issued by the local harbour-
master’s office. These special wastes are:
-oily waters and mixtures (such as bilge water)
-black and/or grey waters from toilet or sinks
-oils (fuels, additives and lubricants)
-chemical substances labelled “TOXIC-NOXIOUS” (battery acid, paints, thinners,
including their containers)
-spray cans containing C.F.C. gas
-exhausted batteries in general
-expired flares
-expired medicines
-products containing lead, mercury or asbestos
-etc.

Grand Soleil 50’

Remember that, according to the EC laws, until the above-mentioned wastes will not be
given to the collectors, you will be considered holder and consequently prosecuted in
case of illegal dumping. Should the trash bins not be available in the harbour area, the
competent authority for the dumping is always the harbour-master’s office.
Main accident prevention regulations (See also the chapter on Safety at page 104)
Although most of the recommendations concerning the accident prevention are dealt with in each
chapter, we think useful to remind you some general rules.
•First of all, it is important to make sure that all compulsory safety equipment is approved by
the law (with a clearly visible label) and that the periodic check is valid. The above-
mentioned equipment includes:
-floating devices (life jackets, lifebelts or “horseshoe-shaped” lifebelts with light buoys
and life rafts o auto-inflatable life rafts);
-distress signals (flares and smoke signals, EPIRB and/or LOCAT, VHF and SSB);
-fixed and portable fire extinguishers (an adequate number, easily accessible and well
indicated);
-approved first aid kit with valid medicines.
Advices
•Make sure that the safety equipment (life raft, lifebelt, etc.) is always available and
ready for use, communicating its position and showing its use to all passengers.
•Do not leave the portholes, hatches and peaks wide open. They could be dangerous pitfalls!
•Check that all handrails, deck walkways and the nonslip surface on the deck hatches
Plexiglas and on the stairs are well fixed, in good conditions and free from slippery and oily
substances.
•Check periodically the efficiency of the equipment: steering gear, standing and running
riggings, winches, blocks, etc.
•Avoid approaching the engine when it is in motion.
•Cantiere Del Pardo delivers all its boats completely well finished and therefore free from
dangers of accidental abrasions. In case you add extra fittings, make sure that you do not
leave exposed sharp and cutting objects such as screws, bolts or sharp edges in general.
•We also want to remind you that the above-mentioned International Convention for the
safety of life at sea provides, among other things, that it is compulsory, at least once a year
and, in any case, before any international voyage, to carry out a rescue simulation at sea
introduced by seven or more whistles or short siren soundings followed by a longer one and
that, at the end, this operation has to be described and recorded in the log book.
•Finally, we recommend you to use sailing gloves and deck shoes while manoeuvring.

Main fire-proof regulations
Although the best materials are used, like fibreglass and wood, which contribute to the creation of a
valuable boat, they easily burn. Therefore, do not hesitate to scold people, when necessary, to avoid
and prevent dangerous behaviours that could cause fire risk.
One of the main fire causes is the failure of the electrical system, caused by the devastating action
of the marine environment that oxidizes and corrodes the electrical contacts, and that becomes an
even more dangerous risk in case of neglected maintenance.
We recommend you to follow the advices contained in this manual and in those of the
manufacturers of the other equipment, in order to minimize the fire risks. In particular:
•do not smoke while inspecting the bilges, the batteries container, or while reaching the
engine or the fuel tank room;
•do not use any fire or flames, either inside or outside the boat;
•do not stow containers or cylinders containing inflammable or dangerous substances in the
peaks;
•observe all use and maintenance rules listed in the paragraph on the gas system;
•do not use portable or provisional heating devices, especially if they have flames;
•check frequently the rooms and bilges next to the engine room in the very first hours of
sailing.
If, notwithstanding all precautions taken, a fire happens, intervene as soon as possible cutting off
the electrical current from all systems, and remember to use:
•fire extinguishers or water in case of solid materials like cloths, coverings, wood, etc.;
•portable dry powder extinguishers in case of electrical components, fuel, oil, etc..
Finally, we want to remind you that the owner has to equip the boat with the necessary
portable fire extinguishers to promptly intervene in case of fire.
According to the Safety Regulations in force, for boats with diesel engine of less than 73,5 Kw (100
HP) power, at least 1 kg. portable dry powder extinguishers duly approved by RINA must be
available in easily accessible locations and ready for use in the following strategically most
dangerous places (see diagram at the next page for the location suggested by Cantiere del Pardo):
•N° 1 for the galley, instruments and electrical equipment in the chart area and in the cabins;
•N° 2 (or one of 2 kg.) for the engine and its systems;
•N° 1 for the aft peak and deck equipment.
Since the Safety Regulations for pleasure boats transfer any responsibility for the efficiency and
good preservation of the fire extinguishers to the shipowner, we advise you to check them, or make
experts check them, asking for the appropriate receipt, frequently or at least at the beginning of each
season.
We remind you that you have to indicate the position of each fire extinguisher by applying the
special red signs in well visible points.

Suggested location for the portable fire extinguishers
•In case of fire it is advisable to gather all extinguishers together in order not to
allow the fire to regain its strength while you are changing extinguisher.
•After using a dry powder extinguisher, it is advisable to immediately clean up
the affected areas to avoid its damaging and corrosive effects.

Haulage and launch
The haulage and launch of boats like the Grand Soleil 50’ is a delicate operation to be carried out
only in well-equipped shipyards under the supervision of skilled technicians.
Lifting
Before starting the lifting operation, carry out the
following checks:
•In order to avoid an excessive slings pressure at
the deck level, we recommend you to join the
slings to a beam large enough to allow them to
stay vertical or preferably with a wide angle at the
deck level while being tightened.
•If you are unable to find a beam, make sure that
the lifting slings are long enough to avoid a too
narrow angle at the deck level, which could cause
an excessive pressure.
•Rinse the internal part of the slings and, if
possible, cover it with packing plastic to prevent
the slings, while being tightened, from scratching,
dirtying and removing the antifouling paint of the
bottom or the gel coat of the sides.
•Remove the label from the log transducer, if
installed.
•Make sure that the slings are steadily fastened or
joinedtogetherinordertopreventthemfrom sliding
towards the extremity of the hull releasing the hold.
•Make sure that the lifting slings have been positioned in a correct way so as not to damage
the S-Drive step with its propeller.
•Do not stop or pass under the range of action of the crane.
For a well-balanced lifting of the Grand Soleil 50’ we advise you to position the slings as follows
(see also diagram at the next page):
•Fore sling: 4,60 m from the extreme bow, that is about 95 cm abaft the 2nd stanchion (from
the bow).
•Aft sling: 7,40 m abaft the previous sling, that is about 55 cm abaft the last stanchion
towards the stern.

Mast
The mast, with 9/10 rig, is equipped with two sets of swept spreaders (that is to say slightly
tilted astern of about 20°) and, passing through the deck, fits itself into a suitable slot in the metal
mast-step, which is directly leant and fastened on the hull ribbings.
Transverse supporting
The entire transversal supporting is made of stainless steel spiral cable or, upon request, of stainless
steel rod. On the transversal side the mast is supported by: higher continuous shrouds;
discontinuous intermediate shrouds and lower shrouds, all aligned with the same axis (see figure
“A”).
Longitudinal supporting
On the longitudinal side, the mast is supported only by the forestay and the backstay (see figure
“B”). The spreader swept allows to not use loose baby stays and shrouds. A double backstay is also
inserted, to adjust the mast curvature in certain sailing points or to keep the forestay always
tightened if the genoa furler is installed.
The entire longitudinal supporting is made of stainless steel spiral cable or, upon request, of
stainless steel rod.

The yacht is normally delivered with the rigging already adjusted by specialized staff and sealed
with lead in order to avoid tampering which could endanger the people’s and the yacht’s safety.
After some weeks a new rigging adjustment could be necessary because of the normal stretching
of the rigging, particularly sensitive if it is made of spiral cable. Cantiere del Pardo is able, at the
customer’s request, to put at his disposal a skilled technician for the above-mentioned final
adjustment.
In that occasion, all adjustment systems will be sealed with lead again. It is important not to
remove any piece without the written consent of Cantiere del Pardo for the whole warranty period.
In any case, we recommend you to be careful, taking the necessary precautions, as an incorrect
use of the standing and running rigging regulation system, could subject the mast and the rigging
itself to anomalous, excessive and then unnecessarily risky effort.
Backstay: instructions and warning
The backstay, doubled in order to be connected to the two chain plates fixed to the transom, can
be adjusted by the provided turnbuckle, which is usually mechanical or, upon request, hydraulic.
Should a hydraulic turnbuckle be mounted, its manual pump is installed on the starboard cockpit
vertical side, towards the stern. Inside the peak, under the starboard cockpit seat, there is the storage
tank for the hydraulic liquid.
Please find some general directions for adjusting the backstay:
•When sailing close-hauled the turnbuckle has to be adjusted according to the force of the wind
in order to reduce the forestay sag: the stronger is the wind, the higher will be the tension.
•When sailing off wind, reduce the tension just enough to eliminate the excessive forestay slack
which could prejudice the mast support.
•We also remind you to occasionally check the hydraulic liquid level in its tank.
Rigging adjustment
Looking at the mainsail split from the bottom upwards, when the mast is under heavy loading, it
should be as straight as possible to the transversal plane.
It is advisable to check periodically the rigging tension and eliminate any further slack with one or
more turns of the turnbuckle.
•If, for any reason, you need to tune the mast again or to check the overall condition of the
rigging adjustment, to ensure the maximum safety of the boat and the optimisation of its
performance, we advise you to consult the Cantiere Del Pardo technicians or other experts of the
field.

Advices on rigging adjustment
These directions and advices for the rigging adjustment are intended for the
technicians who will carry out the operations described below.
Please find, purely as information, a brief memorandum on rigging adjustment:
•when the boat is at the dock with lower sail, check that the backstay is not in tension;
•tighten enough all shrouds in order to eliminate their slack;
•now, looking at the mainsail split from the bottom upwards, it should be as straight as possible;
•tighten the higher shrouds with two or three full turns of the turnbuckle;
•then, before adjusting the lower shrouds, it is necessary to gradually put the mast under sail at
heavy load, preferably at bowline and with the backstay tightened;
•adjust the shrouds on the leeward side on both tacks so that the attachments of the boom, of the
spreaders and of the tightened mast are all on the same transversal plane.
Mast periodic checks and warning
•Check frequently the halyards conditions: if you notice any wear sign, replace them
immediately.
•When hoisting the sails, tighten the last centimetres of the halyards with great
caution, as, if you tighten too much, the splice to which the shackle and the snap
shackle are attached may enter in the mast pulley and consequently get caught or be
damaged.
•In this connection, we recommend you to install the special nylon stop-balls on the halyards
ends; they prevent the splice from entering into the pulley.
•In any case, we recommend you to mark on each halyard, with indelible ink, the security point
beyond which you must never tighten the halyard.
•Check frequently the wear conditions of the shrouds and the stays, in particular near the splices.
•If the mast is equipped with spiral cables, check frequently the cables in general as well as the
splicing point. If you notice even one single broken wire, replace immediately the shroud or the
stay.
•Check periodically that there are no cracks in the point where the spreaders are attached to the
mast; if you see any crack, consult immediately a technician of the mast manufacturer.

•Check the turnbuckle thread: the males with right and left thread must be screwed into the
females with the same number of turns and for a sufficient length to ensure the hold, that is a
distance at least equal to the diameter; check the fixing of the security split pins to avoid tearing
the sails.
•Make sure that the padding of the spreaders ends is always in good condition to avoid tearing
the sails.
•Check periodically that there are no water infiltrations from the gasket of the mast partner on
the deck.
Mast maintenance
•Wash frequently with fresh water the turnbuckles and the halyards lead-blocks.
•Never cover the turnbuckles with plastic pipes or adhesive tape since they prevent ventilation.
