Large Lagoon models: How does is customisation of a catamaran conducted?

Private use, charter, or combination of both, presence of a crew, possibility of long voyages... the choice of layout will largely depend on how the boat will be used.

The configuration options are numerous, but they require decisions to be made early at the start of the project. Within the Lagoon team, the Premium Service team will assist you in carrying out a sustainable, consistent boat customisation that perfectly meets your requirements.

Customisation of Lagoon catamarans: from 65 feet


 Volumes and ways of using space that change the scale of thinking

On large Lagoon units, starting at 65 feet in overall length, the spaces are designed as true living spaces: They are designed to accommodate the crew for long periods of time and allow them to enjoy sailing in exactly the way they want.

Each large catamaran model – Lagoon SIXTY 5, Lagoon SIXTY 7, Lagoon EIGHTY 2 and Lagoon EIGHTY 3 – can accommodate a wide variety of configurations. The layout, design and decoration of the boats are the result of a highly personalised project.
 


The large Lagoon units, all customised

Matthieu Brouillet, Project Manager at Lagoon Premium Service and specialist in large Lagoon units, explains that there is no "standard configuration" for these large catamarans, in the strict sense of the term.

Each customisation project involves:

• A specific navigation programme

• A particular lifestyle

• Clearly identified expectations.
 

On board our brand's luxury catamarans, the volumes, passageways, furniture, equipment, lighting, audio, materials and finishes are carefully tailored to suit the actual uses of the yachts.

Most owners prioritise:
 

• The space and the privacy

• The accommodation capacity

• The functionality linked to a passion or the practice of a sport.
 

With the Lagoon Premium Service, customisation is not an option: According to Matthieu Brouillet, "it is an integral part of the catamaran's conception, starting from the very beginning of the purchase project. Customisation aims to meet the specific needs and desires of a single owner, through consistent, sustainable decoration and layout that perfectly suits the intended purpose".

An essential key factor: the catamaran's use


Private use, charter or combined use: tangible impacts

The first key factor in successfully customising a catamaran is the boat's final use:

A project designed for strictly private use, for example, will not meet the same requirements as a charter-oriented programme or a dual-use programme combining personal navigation and occasional chartering.

These choices directly impact the interior layout:

  • When it comes to private settings, owners often seek more spacious volumes: Larger cabins, more spacious bathrooms, dedicated areas for specific uses, ample storage space, etc.
  • Conversely, for a luxury catamaran available for charter, owners generally prefer layouts that can accommodate more passengers, with a larger number of cabins. The work of the professional crew can also be facilitatated by specific layouts.
     

« Decisions must be finalised at a very early stage, as they will determine the very structure of the catamaran." explains Matthieu Brouillet. "All decisions must be finalised before the catamaran is launched onto the production line. »

 

Customising a Lagoon catamaran: a question of dialogue


A collaborative project

On a large Lagoon yacht, aesthetic and technical customisation is not an individual decision: lThe project is part of a bigger picture, involving different people, each with their own perspective and constraints.

The owner(s) express a vision, desires, a way of life on board... This is complemented by other ways of using the yacht: family life, hosting guests, having a permanent crew, long sailing trips...
 

"The role of the Premium Lagoon Service is to convert everyone's expectations into a coherent and seamless layout. The success of any customisation project depends on our ability to develop a shared vision and functional solutions that are tailored to the actual purpose of the vessel."

Depending on the project, customisation can range from optimising living areas to create dedicated zones for a particular hobby, sport or specific activity on board.

Lagoon's key role and expertise


Ensure the global consistency of the project

Every modification made on board a large Lagoon catamaran involves a number of technical consequences: Even the simplest customisation request has implications in terms of the boat's structure, networks, equipment, or any applicable standards.

For example, modifying a square table to integrate different furniture means that you need to check:
 

  • The positioning of the table stands
  • The strength of the floor
  • The compatibility with the surrounding furniture
  • The adaptation of joinery
  • The suitability of floor coverings...

 

Within the Lagoon Premium Service, our teams share their comprehensive technical expertise. They assess the viability of each project and then carry out a detailed analysis to ensure the overall consistency of the catamaran. Each customisation always guarantees safety, reliability and comfort on board the catamaran.

"Whatever the project, there are always technical considerations to take into account. On a boat, everything is linked together!"

 

A program that evolves

On board a large catamaran, the sailing program may change. A project designed for coastal sailing may eventually lead to longer voyages, private use of the catamaran may become combined use, and the crew composition may change over time.

The Lagoon Premium Service suggests incorporating these potential developments as early as the customisation planning stage. Some structural or material-related modifications, for example, have a long-term impact on the boat.

 

The potential resale

The same logic applies to the question of reselling the catamaran. In order to facilitate a future transaction, it may be judicious to maintain a certain degree of flexibility and avoid irreversible choices:

"The choice of loose furniture, woodwork, upholstery, panelling and materials for worksurfaces, for example, helps to create a unique identity for the boat. These elements are used to create different atmospheres, allowing for great freedom of expression and remaining adaptable over time. In order not to compromise any future resale plans, we recommend keeping this adaptability in mind, as it will become particularly relevant 5 or 10 years after the boat is delivered."

The Lagoon Premium Service support allows you to consider the advantages and disadvantages of each option.

 

The identification of alternatives

When certain suggestions cannot be carried out as they are, particularly for structural reasons, the Lagoon Premium Service will propose alternative solutions. These comply as closely as possible with the original intention and fully meet the objectives of use.

Our project managers use their experience and expertise to support the projects they work on, and are a source of new ideas: They collaborate with the future owner(s) until they achieve a perfect customisation, which is entirely feasible.

 

From decorative details to major renovations, the same high level of quality is maintained.

Whether it's a modification of the decoration or a major structural change, every request for our brand's large motor or sailing catamarans is carefully considered by Lagoon's Premium Service.
