[quote=ess105]This is a good question. PotE (sorry for referring to you as Obesity earlier) - do you have a deeper explanation for what is being weighed now versus what was weighed before?

Dear All,

Many dealers and customers have recently questioned us about the weights of
our boats that do not seem in line with the weights announced by our
competitors. Of course, the Lagoon catamarans are not heavier than the one

from our competitors. This difference in weight comes from a new EEC rule
that Lagoon follows since September 2005 in our brochures and it seems that
most of our competitors do not follow this new rule yet.

In order to help you to understand, please find here after some
explanations about the displacement figures under the EEC rule:
Today the rules are simple but somewhat confusing:
An empty weight does not mean anything anymore.

Manufacturers have the choice of giving what the EEC regulation call an
"empty displacement", a "Light displacement" or a "maximum loaded
Displacement"

(1) The Empty weight includes the following:

No equipment at all except the weight of the boat with the largest engine
option

(2) The Light displacement includes:

The whole boat including all what comes in the standard (rig, sails,
batteries, etc.) + a safety equipment (without life raft) + the heaviest

motorisation that the boat is marketed with.

(3) The maximum loaded displacement includes:

All of the above + the whole list of options (i.e. all the options printed
in the option list and that are listed without restriction (if, for

instance, the option list electrical tender lift and davits, the option
list must state that they are not compatible and the heaviest option must
be selected for the weight estimate)) + all the tanks filled up (including

grey or holding tanks) + the maximum number of crew members listed in the
lowest navigation class (so if an offshore boat has 30 people
classification in the D class, that is what must be taken in account).

On top of this, personal belongings for all crew, food, drinks, bed and toilet,
fabrics and kitchen gears must be added. It comes to a huge number, this
will never happen, but states the maximum loading capacity of the boat

according to the EEC regulations.

Since September 2005, all weights indicated in our brochures are EEC
weights.

So, for example,

For the Lagoon 380-S2, we have the 3 following figures :

- empty weight : 6,91 T
- light displacement : 7,26 T
- max displacement : 10,46 T

For the L410-S2 :
- light displacement : 7,52 T
- max displacement : 11,34 T

For the L440 :

- light displacement : 12,15 T
- max displacement : 18,05 T

In the mean time, our boats have changed a lot : the use of infusion (on
the Lagoon 420, 470, 500, 570 and above have saved about 30% of weight in

the hull and deck lamination), but in the mean time, our platform have
grown in length, width, and the volume of the hulls has increased also, in
order to offer more comfort inside. Also, designers have improved the hull

lines performance, with a better volume distribution, a better keel line,
etc.

So today, we can confirm a few facts: the average speed of the new
boats is higher than the one they replace, but the top speeds are lower. In

fact, the sail/displacement ratio has not changed, but the improvement in
the capacity of carrying the displacement makes our new boats more high
performance.

The excellent results of the Lagoon catamarans in the last transatlantic

rally ARC is the proof that the Lagoons are at least as fast as most of our
competitors, if not even faster!

Please do not hesitate to spend some time explaining those width issues
with your customers. If some customers are worried about the weight of our

boats, please tell them to make sure that they are really comparing the EEC
weight of our competitors.

The Lagoon team is at your disposal to help you on this matter, so please
do not hesitate to ask.

Best regards.

The Lagoon Team.
