Lagoon 620 User manual

We share a common passion for the sea ; we, LAGOON, as catamaran builders
and you who want to live your passion on the seven seas.
We are delighted to welcome you to the family of LAGOON catamaran owners
and we congratulate you on it.
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 her use and maintenance. Read this guide
carefully before you put out to sea so that you can make the most of her and
avoid any damage and above all any further problem. Read it and get to know
your boat before using her.
In order to share with you as much new technology, new equipment or
materials and company experience, our boats are constantly improved. This is
why the specifications and information given are not contractual and may be
modified without notice and without obligation of updating.
This instruction guide has a general purpose and may sometimes mention
some equipment or accessories or deal with some points that are not relevant
to your own boat ; if in doubt, refer to the inventory you were given 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 ensure your safety
and comfort. Your dealer, your international sailing association or your yacht
club will be very happy to recommend local sailing schools or profesional
instructors.
Although everything possible has been planned and designed with the safety
of the boat and her users in mind, remember that sailing is highly dependent
on the weather conditions and the sea state, 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, C and
D 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.
Our network of LAGOON authorized dealers will be at your
disposal to help you get acquainted with your boat and will
be the most qualified to take care of her maintenance.
Always read and listen to the weather forecast before you
put out to sea.
Make sure that the forecast sea and wind conditions will
correspond to the category of your boat and that you and
your crew are able to handle the boat in these conditions.

The sea and the water are not the natural environment of Man and he must
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 badly 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", international regulations for preventing 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 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 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 layout of the weights (installing a radar, modifying the mast, changing
the engine, etc.).
The users of the boat are informed of the following :
- The entire crew must be properly trained.
- The boat must not carry a load heavier that 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 load
carried by the boat must be properly distributed.
- The water in the bilges must be maintained at a minimum.
- Stability is reduced when you add weight in 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 coming in.
- Stability may be reduced when you tow a boat or lift 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 (harness, flares, life raft,
etc.) according to the type of boat, the country in which she 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.).
- Anyone 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
permanently.
For essential or optional equipment (engine, electronics,
etc.) refer to their respective manuals supplied with your
boat.
Keep this manual in a safe place and hand it on to the new
owner if you sell your boat.
