LAGOON 421
Owner's Manual
We share a common passion for the sea: we, LAGOON as shipbuil-
ders and you who want to live your passion on the Seven Seas.
We are delighted to welcome you to the great family of LAGOON boat
owners and we congratulate you on it.
This manual was meant to help you to enjoy your boat comfortably
and safely. It includes the boat specifications, the equipment provided
or installed, the systems and tips on her operation 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 any trouble. Get to
know your boat before you sail.
We keep improving our boats as we want you to benefit from the tech-
nological developments, new equipment or materials and our own ex-
perience. That is the reason why the specifications and information
given are not contractual, they may be modified without prior notice or
up dates.
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 change to a new type of boat which
you are not used to, get some training in boat control and sailing to en-
sure your safety and comfort. Your dealer, your international sailing
association or your yacht club will be very happy to recommend local
sailing schools or professional instructors.
Even if everything has been provided for and designed for the safety
of the boat and the safety of her users, don't forget that sailing highly
depends on the weather conditions, the sea condition, 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 the design
categories A,B or C are changeable and are dependent on the ha-
zards of unusually strong waves or gusty winds. Therefore total safety
cannot be guaranteed, even if your boat meets the requirements of a
category.
Our network of LAGOON authorized dealers will be at your dis-
posal to help you get acquainted with your boat and will be the
most qualified to take care of her maintenance.
Always listen to the weather forecast before you put out to sea.
Make sure the sea and wind conditions will correspond to the
category of your boat and you and your crew are able to han-
dle the boat in these conditions.
The sea and the water are not the natural environment of Man and one
has to respect their laws and strength.
Adapt the use of your boat to her condition that wears out with time
and use.
Any boat, however solid she may be, may be severely damaged if ba-
dly used. This is not compatible with a secure navigation. Always
adapt the speed and direction of your boat to the conditions of the sea.
The 'COLREG', an international regulation in order to prevent collision
at sea, published by the International Maritime Organization, specifies
the steering and course regulations, the navigation lights etc. throu-
ghout the world Make sure you know these regulations and you have
on board a manual that explains them.
In numerous countries, a licence, an authorization or a training course
is requested.
Make sure you have this legal authorization before you use your boat.
Always use an experienced technician for the maintenance of your
boat, the fitting of accessories and the carrying out of small modifica-
tions. The written authorization of the builder or his legal representati-
ve is compulsory for modifications that alter the specifications of the
boat, in particular the vertical layout of the grounds (putting up of a ra-
dar, modification of the mast, change of the engine etc.).
The users of the boat are informed of the following:
- The entire crew must be trained properly.
- The boat shall not be loaded more with than the maximum load re-
commended by the builder, in particular the total weight of the food
supplies, of the different equipment that are not supplied by the buil-
der and of the persons on board. The weight of the boat shall be pro-
perly distributed.
- The water in the bilge shall be kept at its minimum.
- The stability is reduced when you add weight in the upper parts.
- In case of heavy weather, the hatches, lockers and doors shall be
closed in order to minimize the risk of water coming in.
- The stability may be reduced when you tow a boat or when you lift
heavy weights with the davits or the boom.
- Breakers are serious dangers to stability.
- In the boat there shall be all the proper safety equipment (harness,
flares, liferaft etc.) depending on the type of boat, the country, the
weather
- The crew must be familiar with the use of all the safety equipment
and the emergency safety procedures (MOB, towing etc.).
- Anyone on the deck shall wear a life jacket or a buoyancy aid. Please
note that in some countries it is compulsory to wear an homologated
buoyancy aid permanently.
For the essential or optional equipment (engine, electronics
etc.) refer to their respective manual delivered with your boat.
Keep this manual in a safe place and hand it over to the new
owner if you sell your boat.
