Please read the important safety information and read the
Assembly Manual before sailing your boat.
BEFORE YOU GO SAILING
 Check you are wearing suitable clothing and safety
equipment for the conditions and time of year;
 Secure the drain plugs before sailing and ensure that the
hulls are free of water. Ensure that any hatches are cor-
rectly fitted and have a good seal;
 Carry your Nacra or use beach wheels with cradles when-
ever possible to minimize keel wear;
 Make sure a third party knows where you are sailing and
how many people accompany you;
 Check the weather forecast;
 Check the time of high and low tides if applicable;
 Seek advice of local conditions if sailing in a new area.
 Always check the condition of your craft before setting
off.
SAILING AND BEACHING
 Never sail above your ability or that of your crew;
 A sailor’s safety knife should be carried on board;
 When launching through the surf, always make sure the
bow is facing the waves.
 Always know the direction that the wind is blowing;
 Watch out for changing weather conditions;
 Ensure that you and your crew can cope with any
changes in the weather conditions;
 After sailing, remove drain plugs to equalize the pressure
in the hulls, if no drain plugs installed, open the hatches;
 Understand and be competent in the sailing skills and
righting techniques.
RIGHTING AFTER A CAPSIZE
Even the best sailors capsize occasionally, so prepare your-
self and the boat for the inevitable. Install a righting line
onto the dolphin striker rod below the mast.
The boat will lose speed as it raises up on one hull and usu-
ally capsizes over slowly. Hang on to the boat, being careful
not to separate yourself from the boat if possible.
As the boat capsizes you may be located in the water or on
the top hull above the water, try to get as fast as possible
onto the bottom hull. It is important to get yourself to the
bottom hull as quickly as possible to prevent the boat from
turning upside down (turtle).
Do not let go of the boat, as the current and the wind
may make it hard or impossible to get back onto the
boat.
Release the main, jib and spinnaker sheets. Reach around
the front crossbar, and throw the righting line over the top
hull. Make sure that the bows of the hulls are facing into the
wind. Move your weight towards the bow to turn the boat
to obtain the proper angle. Be careful not to shift your com-
bined weight too far forward or afterwards as this may
cause the boat to roll over and turn turtle. If the mast is
pointed directly into the wind, the boat may turn over to the
other side when you get the boat upright
Standing even with the front crossbar, the skipper and crew
should grab the righting line, and hike out backwards. You
can tie knots in the righting line to prevent your hands from
slipping during this procedure. If you are single handling,
you may need to carry a righting bag to attain the necessary
weight to the boat upright.
Once the tip of the mast starts to come out of the water, the
boat will right quickly. Be sure to hold onto the righting line
until you can grab the boat and pull yourself up onto the
deck. Be careful to avoid being hit by the dolphin striker as
the boat comes down on top of you. One of the crew should
reboard over the front beam of the catamaran onto the
platform to ensure that the craft can not sail away without
the crew. The remaining crew can be recovered by the side
with the aid of the trapeze wires or crew. Stow the righting
line, organize the sheets, and you are sailing again!
Minimum crew weight required for righting:
Nacra 460 102 kg
Nacra 500 102 kg
Nacra 570 110 kg
Nacra 580 130 kg
Nacra F16 104 kg
Nacra F18 Infusion 140 kg
Nacra 17 116 kg
Nacra F20 Carbon 150 kg
3. important safety information
WARNING!
Always wear an approved buoyance aid or
lifejacket.
WARNING!
Check for overhead cables when raising or lower-
ing the mast, launching and sailing the boat. So
look up when moving the craft around and give
any wires a wide berth. A mast which comes in
contact with electrical power lines can cause seri-
ous injury or death!

Important safety information
STABILITY AND BUOYANCY
The Nacra catamarans are equipped with one or more
sealed buoyancy compartments. The buoyancy compart-
ment is inserted during the build of the hulls. Consequently
the following points should be noted:
 Do not puncture the buoyancy compartment.
 When the buoyancy compartments become punctured
do not use the craft until the compartment is repaired.
 When a hatch is not closed correctly do not use the craft
until the hatches are fitted correctly.
 You may have to replace fittings from time to time.
Ensure that all fastenings are resealed properly using an
appropriate sealant.
The IMCI assessment of these crafts by determined that the
crew can upright the craft and will subsequently float. Each
of the Nacra Catamaran listed in the Declaration
of Conformity have been certified as conforming with the
requirements of the UK Statutory Instrument 2004 No 1464
Consumer Protection; the Recreational Craft Regulations
2004 Schedule 1
 Parts of Sections 3.2 &3.3; and the EU Recreational Craft
Directive 2003/44/EC Annex VI
 Module Aa & Annex 1 –Parts of sections 3.2 & 3.3.
TRAILING AND STORAGE
When trailing your Nacra you should only use an approved
road trailer. Tying down the craft to its trailer is important
because too much or too little tension could result in dam-
age.
Follow the instructions below for safe trailing:
 Ensure the catamaran is properly located on the road
trailer and that the boat is balanced correctly. Always
use trailers and beach trolleys with cradles designed to
fit the hulls rather than rollers. Risk of damaging the hulls
occurs when using trailers and dollies without proper
support
 Make sure that the catamaran is not too far forward
otherwise it may come into contact with the side of
your car as you turn corners.
 Tie the catamaran down to the trailer by using two
straps across the width of the hulls using the eyelets on
the frame of the trailer. You only need to apply suffi-
cient tension to hold the catamaran in contact with the
trailer. Use padded material where any straps touch the
deck.
 Always remove dagger boards, blocks, and rigging when
tailoring. Removal of the rudders and steering system is
recommended for long distance tailoring.
 Do not use the dolphin-striker as a tie down or for
pulling the boat. Use the main beam instead.
 Secure both ends of the mast. Be sure to mark off both
ends of the mast for visibility.
 Boat covers are recommended to protect against rocks,
gravel and road debris while trailing. These covers also
provide good protection from weather and the ele-
ments.
 Always leave the drain plugs and inspection hatches
open to avoid possible air pressure damage.
TOWING AFLOAT
Should it become necessary to tow the craft, you should
secure the towing line around the Front Cross Beam on one
of the sides and as close as possible to the hull. Raise the
daggerboards (if fitted) and stay at the tiller. In the event of
the loss of the rudder
sit well aft.
ANCHORING & MOORING
Mooring or anchoring of your boat is not recommended.
However, if the boat is moored in the water the warranty
must be complied with. Barrier and anti-fouling paint must
be applied to the bottom.
The Nacra range of catamarans are not normally required
to anchor/moor, as they are day boats for racing or cruising
in inshore or inland waters.
OUTBOARD ENGINE
The Nacra range of catamarans are not designed for use
with an outboard engine.

4.2. owner Assistance
If you experience any concerns.
Two-Stage satisfaction procedure
ONE –Discuss your concern with a member of the
authorized Nacra dealer - or service centre management.
Concerns can often be resolved quickly and satisfactorily at
that level. If the concern has already been reviewed with the
sales or service manager, contact the owner of the author-
ized Nacra dealership/service centre or the general manager.
TWO –In the unlikely event that your concern cannot be
resolved by the authorized Nacra dealer or service centre
management, contact Nautical Sports BV at
[email protected]
By doing so you should be prepared to provide the following
information in English:
 Your name, address, telephone number and e-mail.
 The identification HIN number of your boat (This can be
found on the starboard hull stern)
 The name and address of the dealer.
 The delivery date of your boat.
 Details of your concern or request.
 Including photos and/or quote of repair.
Storage
It is most important that you store your boat properly, please
see page 8 of this manual how your boat should be stored.
Please make sure in case you store your boat for longer
periods it’s stored in a well ventilated area in order to avoid
an osmosis reaction between hulls and any (transport) sup-
ports.
Transport
To make sure that no damage is done to your boat, please
see page 8 of this manual.
MAINTENANCE—GENERAL INFORMATION
It is essential that your boat receives the maintenance out-
lined on the following pages to retain the safety, reliability
and performance built into your boat.
Do not leave the rig under tension when not sailing or during
storage. If rig tension is over tightened, or left on when not
sailing damage may occur.
Your boat should only be used with a proper launching trol-
ley. The use of any other trolley may damage the hull and
invalidate your warranty. Care must be taken to support the
hull adequately if the boat is not stored on the correct
launching trolley. Any sustained point loading could perma-
nently dent or distort the hull.
Any repairs to the hull should be undertaken by qualified
personnel with the relevant skills and equipment. Contact
your dealer for advice.
UV light may cause fading to some components and fittings,
a good quality cover is recommended to reduce UV degrada-
tion. Keep the equipment clean by frequently and
thoroughly flushing with fresh water.
Excess water should be removed from the hull and any cavi-
ties. Keep your craft drained and well ventilated. Ensure the
craft is stored with the bow raised to allow water to drain
away. Make sure that when you attach the rudder that
the rudder stop clips over the stock.
Salt water will deteriorate your sail and the stitching if the
sail is not rinsed in fresh water after sailing. Sails should be
dried before storing. Ideally we would recommend that you
should store sails in a convenient dry place away from the
craft. If you have to store sails on the craft ensure that a
good cover is used and that it prevents any water
coming into contact with the sails. Sails will be subject to
mould and mildew if left in water.
Trailers should be rinsed with fresh water and checked at
regular intervals. It is recommended that the trailer be ser-
viced annually. It is also a good idea to tie the craft down
when it is left in the dinghy park to prevent any damage
in the event of strong winds.
REPAIR
Contact your dealer or Nautical Sports BV for the best advise
MODIFICATIONS
Contact your dealer or Nautical Sports BV about any modifi-
cation. Please remember any modifications may endanger
your safety and invalidate your warranty.
CAUTION!
Always wash your boat with fresh water after
sailing. Salt water can cause severe corrosion

 Check mast ball for wear- replace if:
a) Maximum diameter of the plat spot on top of the
ball is bigger then 15mm/0.59 inch
b) Minimum height from bottom to top should be 35
mm/1,38 inch
 Check hulls for excessive wear on bottoms from beaching
and dragging the boat.
 Check hulls for leaks at all hull fittings by covering sus-
pected areas with soapy water and blowing air (from your
lungs) into the drain plug holes.
DO NOT USE COMPRESSED AIR AND OR ANY OTHER
TYPE OF MECHANICAL BLOWER AS THE EXCESSIVE
PRESSURE CAN DAMAGE THE HULLS.
 If the water bubbles, there is a leak. Remove the fitting
and/or cover with silicone sealant and replace. If the leak
is from fiber glassed area (no fittings) this should be re-
glassed to insure proper permanent bonding. Please see
your dealer
Sails
 Check for broken or delaminated battens. Never sail with
damaged battens.
 Check the sails and trampoline for tears, or loose
stitching. Repair immediately to avoid further damage.
Please see your dealer
Rigging
 Periodically check for and replace frayed, worn, or
kinked wires, shock cords and lines.
 Periodically check the bearings in the traveller car and
replace them if necessary. Rinse thoroughly with fresh
water to free any stuck bearings.
 Periodically check dolphin striker strap tension. Please
see assembly manual for the correct setting for your
boat. Adjust as necessary.
 Masts should be regularly inspected for water tightness
and diamond wire wear. Make sure fittings are sealed
with silicone.
 Replace wires that show any signs of wear. Check dia-
mond wire attachment points, turn buckles and seizing
wire. These areas could cause serious mast failure!
Conditions which requiring more frequent owner mainte-
nance
If your boat is regularly operated under one or more of the
following conditions:
 Temperatures below freezing or above 32°C / 90 F
 Take extra care when boat is left after sailing when freez-

Each carbon-fibre mast delivered by Nacra has been manu-
factured using heat and pressure autoclave curing, the best
process available.
Since carbon fibre composite is different than aluminium to
drill, file, or otherwise process, always contact your Nacra
dealer for advice before making any modifications to the
mast.
Handling & Storage
Carbon fibre has properties differing from aluminium.
Though carbon composite is stronger than aluminium, it is
less resistant to impact loads. Where aluminium will dent on
severe impact, carbon composite could shatter or suffer
serious delaminating. Clearly, subjecting your carbon spars
to severe impact is to be avoided.
When transporting your mast it is important to pack it well
using covers which are available at your Nacra dealer.
Ensure that rigging is removed to prevent the stays from
wearing or banging against the mast. It is recommended to
fully inspect your mast when re-rigging your mast.
Care
In order to get the maximum life from your carbon fibre
composite tubing we recommend the following care and
precautions:
 Do not allow the mast to become excessively hot.
High performance epoxy resins, together with oven post
curing, are used in the tubes, however at temperatures
above approximately 75oC the epoxy can soften which
dramatically reduces strength or otherwise can cause
the tube to bow or warp. Note that black objects are
the best absorbers of IR radiation (heat) and we have
recorded a surface temperature of 65oC from a tube
lying flat on the ground in the sun.
 Epoxy resins are UV light degraded. Although our ep-
oxy resins have UV light protection, excessive UV light
has the effect of turning the exposed epoxy resin into a
chalky layer. Therefore it is recommended to keep your
mast as much as possible out of the UV light . It is best
to cover it when not rigged. Therefore it is also recom-
mended to wax your mast with any UV protection wax
e.g. Teflon wax etc.
