Lagoon 440 S2 User manual

User’s gguide

We share a common passion for the sea: we, LAGOON, as boat-builders and
you, who want to live out your enthusiasm for the ocean.
We are delighted to welcome you to the great family of LAGOON boat owners
and we would like to congratulate you on your purchase.
This instruction guide is intended to help you to enjoy your boat in comfort and
safety. It includes the boat specifications, the equipment provided or installed,
the systems on board and tips on use and maintenance. Read this manual
carefully before you put out to sea so that you can make the most of her and
avoid any damage and difficulties. Read it carefully and familiarize yourself
thoroughly with your boat before sailing.
In order to share as much new technology, new equipment and new materials
with you as possible, our boats are constantly improved. This is why the
specifications and information given are not contractual and can be modified
without notice and we are not obliged to provide updates.
This instruction guide has a general purpose and it may mention some
equipment or accessories or deal with some points or questions that are not
relevant to your own boat ; if in doubt, refer to the inventory that you received
on delivery of your boat.
If this is your first boat or if you are changing to a new type with which you
are not familiar, first obtain some training in boat handling and sailing to
ensure your safety and comfort before taking the helm of your boat. Your
dealer, international sailing association or yacht club will be able to
recommend local sailing schools or professional instructors.
Although everything possible has been planned and designed with the safety
of the boat and its users in mind, remember that sailing is highly dependent
on the weather conditions and the conditions of the sea, and that only an
experienced and very fit crew, handling a well-maintained boat, can sail
satisfactorily.
The sea and wind conditions that correspond to design categories A, B and C
are changeable and are still susceptible to the risk of unusually large waves
or strong gusts of wind. Total safety cannot therefore be guaranteed, even if
your boat meets the requirements of a category.
Always consult the weather and shipping forecasts before
taking your boat out to sea.
Make sure that the sea and wind conditions forecast
correspond to the category of your boat, and that you and
your crew are able to handle the boat in these conditions.
Our network of LAGOON authorized dealers is available to
help you get acquainted with your boat and is best qualified
to take care of her maintenance.

The sea and the water are not Man's natural environment and we must
respect their laws and their strength.
Adapt the use of your boat to her condition, which deteriorates with time and
use.
Any boat, however well built, may be severely damaged if badly used. This is
not compatible with safe sailing. Always adapt the speed and direction of your
boat to the sea conditions.
The 'COLREG' international regulations for the prevention of collisions at sea,
published by the International Maritime Organization, specify the rules relative
to steering and courses, navigation lights etc. throughout the world. Make sure
that you are familiar with these regulations and that you have a list present on
board which explains them.
In many countries, a license, an authorization or training certificate will be
required.
Make sure you have the necessary legal authorization before you use your
boat.
Always ensure an experienced professional carries out the maintenance of
your boat, installs any accessories and makes any small modifications. The
written authorization of the builder or his legal representative is compulsory
for modifications that alter the specifications of the boat, in particular the
vertical arrangement of forms (installing radar, modifying the mast, changing
the engine etc.).
Users of the boat are informed of the following:
- The entire crew must be properly trained.
- The boat must not carry a load heavier than the maximum load
recommended by the builder, in particular the combined weight of food
supplies, equipment not supplied by the builder and people on board. The
weight carried by the boat must be properly distributed.
- The water in the bilge must be maintained at a minimum.
- Stability is reduced when you add weight to the upper sections.
- In the event of heavy weather, the hatches, lockers and doors must be closed
in order to minimize the risk of water entering the boat.
- Stability may be reduced when towing another boat or when lifting heavy
weights using the davits or the boom.
- Breaking waves are a serious danger to stability.
- If your boat is equipped with a life-raft, read the instructions carefully. All the
proper safety equipment must be carried on board (harnesses, flares, life-raft,
etc.) according to the type of boat, the country in which it is used, the weather
conditions, etc.
- The crew must be familiar with the use of all the safety equipment and all
emergency safety procedures (MOB, towing etc.).
- All people on deck must wear a life jacket or a buoyancy aid. Please note that
in some countries it is compulsory to wear an approved buoyancy aid at all
times.
Keep this manual in a safe place and give it to the new
owner if you sell your boat.
For standard or optional equipment (engine, electronics etc.)
refer to their respective manuals supplied with your boat.

Getting under way
The sliding door locks in three different positions: closed, ajar (airing
position) and open.
A latch on the doorframe enables locking from inside the saloon.
Switch on the main power of the boat by activating the battery
switches located in the port and starboard aft cabins, then activate
the different accessory switches on the electrical panel.
Check the charge rate of the batteries, the water level in the tanks and
the fuel level (see ELECTRICITY and MOTORIZATION chapter).
Carry out the inventory of compulsory safety equipment and instruct
the crew concerning its location and operation.
Visibility in navigation
The international regulations to prevent collision at sea (COLREG) and
course regulations make mandatory a permanent and proper
surveillance and the respect of priority.
Make sure there is no other boat in your way.
Visibility from the steering station may be obstructed by the following:
- Load and load distribution.
- Sea conditions, rain, spray, fog or darkness.
- Lights on inside the boat.
- People and mobile equipment in the helmsman's field of visibility.

zBEWARE
A catamaran presents 6 times greater heel resistance than a single-
hull vessel. In terms of ship design we speak of righting moment
(multiplication of the vessel's weight by the transverse distance
between the centre of gravity and the centre of flotation (or
buoyancy).
See illustration on previous page.
This fact has real consequences for the handling and sail-trimming of
a catamaran.
The fact that the boat will not heel over could conceal an excessive
sail surface area in use, which could be dangerous for the crew and
the vessel. It is therefore essential to constantly monitor the real wind
speed and to trim the sail surface area as a priority in accordance
with this speed.
These latter adjustments are valid in calm seas. In rough seas one
should take the precaution of reducing 10% earlier in terms of real
wind speed. Generally speaking, it is essential to constantly look to
relieve the vessel rather than to put it under stress.
One should always look for the sail angle of attack to be headed to the
apparent wind and the sails to be not over-trimmed so that the
airflows leaving the sail are parallel to each other, that is to say they
do not create turbulence behind the sail.
Failure to follow the above recommendations can be dangerous for
the boat and the crew, and the manufacturer cannot be held
responsible in the event of an accident.
zCLOSE HAULED TRIMMING (between 75 and 50° to true wind)
GGiivveennwwiinnddffoorrcceeiinnaappppaarreennttwwiinndd
- FFrroomm00ttoo1166kknnoottss: full sail; mainsail traveler 30 cm to windward of
center, mainsail trimmed with a slightly opened leech (boom
centered).
The Genoa jib is trimmed near the spreader, the Genoa traveler is
placed so that the angle of the Genoa sheet forms a straight line with
the clew and the luff, at 40% of its height.
- FFrroomm1166ttoo2200kknnoottss: full sail; the mainsail traveler moves up to 60
cm to windward of center, mainsail trimmed with a slightly more open
leech (boom still in line: so the sheet will have to be slackened).
The Genoa traveler does not change position but adjust the sheet so
that the leech is 10 cm from the spreader.
- FFrroomm2200ttoo2266kknnoottss: 1 reef, full Genoa; the mainsail traveler comes
back to 30 cm to windward of center.
The Genoa traveler does not change position but the sheet is
slackened slightly so that the leech is 20 cm from the spreader.
- FFrroomm2266ttoo3300kknnoottss: 1 reef, 75% of the Genoa; the mainsail traveler
moves up to 60 cm to windward of center.
The Genoa traveler remains in place or moves slightly forward but it
is adjusted so that the leech forms a propeller, the upper part
dumping air out under strong gusts of wind.
- FFrroomm3300ttoo3366kknnoottss: 2 reefs, 60% of the Genoa; the mainsail
traveler returns to the 30 cm to windward of center, the boom is
slackened to fly 50 cm leeward.
The Genoa traveler is moved slightly forward, the adjustment remains
the same.

WARNING
Your boat is designed to sail without the need to
climb onto the roof for any maneuvers. It is
dangerous to climb or stay on the roof particularly in
the event of gibing.
Keep children under close supervision.
RECOMMENDATION
Under sail put all engine controls in neutral to avoid any
damage to engines (with fixed or folding propellers).

zREDUCING SAIL
The boat is fitted with 3 reefs.
Reefs n°1 and n°2 are automatic, n°3 is traditional.
The luff eyelet of reef n°3 is fitted with a strap with a snap shackle to
clip on to the eye bolt on the boom.
Putting in reefs n°1 and n°2:
1 - Head the boat into the wind.
2 - Pull tight the topping lift.
3 - Slacken the mainsail sheet.
4 - Slacken the mainsail halyard and then trim reef line n°1 or n°2,
as needed, until the reefing blocks which correspond to the luff and
the mainsail leech are a few centimeters from the boom.
5 - Close the line cam cleat of the respective reef.
6 - Hoist taut the mainsail halyard.
7 - Slacken the topping lift and take in the mainsail sheet.
Follow the lowering and raising of the sail with the help of the head
downhaul.
Putting in reef n°3:
Repeat steps 1 to 3 as before, then:
4- Slacken the mainsail halyard then trim reef line n°3 until the
mainsail leech block is a few centimeters away from the boom.
- Clip the snap shackle on the luff eyelet of reef n°3 onto the eye bolt
located on the boom.
- Take up the slack in the lines of reefs n°1 and 2.
- Repeat steps 5 to 7 as before.
Refer to the running rigging diagram (chapter on RIGGING AND SAILS)
for identification of ropes.
zNAVIGATION WIND ASTERN
- Do not fall off more than 150° to the apparent wind.
- Put the traveler out as far as possible and slacken the sheet slightly.
- Make sure the mainsail does not touch the shrouds; the rubbing of
the battens will wear the material and cable very rapidly.
- Keep mainsail + solent up to 15 knots speed and put in one reef or
more if the accelerations are sudden and strong or if sea conditions
deteriorate.

Mooring
A sufficient number of dockside lines of a size suitable for the
environment should be on board for mooring your boat.
- Always maneuver your boat using the engine.
- Make allowances for currents and wind when handling your boat.
- Protect your boat properly with suitably sized fenders.
- Always keep the dockside lines clear and stored away.
- Maneuver at a reduced speed.
AFTER MOORING
- Protect the dockside lines from chafing with chafe guards.
- Allow for tide variations if necessary.
Towing
TOWING
- Tow another boat at a reduced speed and as smoothly as you can.
- Be particularly careful when throwing or catching the towing line (it
may catch on the propeller).
N.B.: Stability may be reduced when towing a boat.
BEING TOWED
- Keep steering your boat and ensure you stay in the wake of the
towing boat.
Anchoring
As a rule, set the anchor line at least 3 times the water depth.
zPREPARATION OF ANCHORING (illustrations following page)
- Install the bridle by fixing it to the chain plates located at the ends
of the fore beam.
- Put the bridle through the stem bow roller.
- Shackle the bridle to the central cleat during the lowering of the
chain.
zMANUAL ANCHORING
- Point your boat into the wind and at zero speed.
- Release the brake on the chain lifter.
- Pay out the chain while reversing slowly.
- Secure the anchor chain on the bridle.
- Lead out the chain until the guy becomes taut.
