Autonomy and Range: Lagoon’s Solutions for Passagemaking

Energy production and storage, freshwater management, ecological innovations… in this article, we will review the various solutions developed by Lagoon to make your cruise the perfect travel experience.

October 13, 2025

To cruise for hundreds or even thousands of nautical miles, without having to stop for provisions… this is the dream of numerous cruisers.

If it is also yours, there is good news:  we have designed Lagoon catamarans so that each crew can cruise with the greatest autonomy.

Fuel Range, Essential for Offshore Cruising

If you are planning to cruise aboard a catamaran, you probably already know:  when cruising offshore, far from ports and provisioning points, fuel and water autonomy is the gauge of freedom

Self-sufficiency in water and in electricity, and notably storage capacity, enable cruising with greater flexibility.

As the owner of a Lagoon power or sailing catamaran, you can enjoy the sea at your own pace and adapt your travel plans to suit your interests and preferences, without having to worry about making frequent stopovers to meet the needs of the boat and her crew.

 

Aboard a Lagoon, Greater Freedom to ravel

First, large-capacity fuel tanks aboard our various models will enable you to envision cruising to your dream destinations, even those far-away destinations that, in other circumstances, would be unattainable!

With a capacity of between 300 and 8500 liters, the fuel tanks aboard Lagoon catamarans enable cruising for days – or even weeks – at a time, whatever the weather conditions may be, in comfort and with full autonomy.

But the ability to choose one course over another, an anchorage that is further away and less frequented, extending an enjoyable stopover… all of this depends directly on the storage capacity of your catamaran, and whether or not to produce water and electricity.

Sometimes, it is even a question of safety:  it is the autonomy of the boat regarding these resources that will enable you to adapt or change your cruising itinerary, in the case of bad weather conditions, for example.

Finally, for those traveling long distances, limiting resupply stopovers when you do not need to refuel or restock freshwater is an important time saver.

With fewer logistical constraints, you can spend more time enjoying moments on the water!

Evaluate Energy Use and Water Requirements

It is impossible to discuss fuel and water autonomy aboard a catamaran without talking about the real needs of the crew. In function with your cruising  and travel plans and your future destinations, you will not necessarily require the same storage capacity and equipment on board.

Before a long passage or big cruise, we advise you to evaluate your fuel, energy, and freshwater needs – notably, by taking account of the estimated time and distance between stopovers, the number of people on board, and the type of activities planned.

Lighting, electronics, water pumps, the refrigerator, the freezer... for energy autonomy while cruising, consider making precise estimations of the real energy consumption of each piece of equipment!

Energy on Board:  Fuel Autonomy in Locations Around the World


Equipment to Capture and Store the Sun’s Energy


Lagoon catamarans have been designed, from the beginning, so that energy needs are never a constraint.

It was unthinkable, for us, that you could not comfortably enjoy your boat while running the engine regularly.

Aboard our boats, energy production is easy and efficient, notably with solar panels, integrated into the design of the boat, or added later, as an option.

The power installed varies with each model:  a Lagoon 38 can generate up to 1.42 kW, while the production capacity aboard a Lagoon 51 Iconic, boasting extra-large solar panels, exceeds 3.4 kW.

Aboard our sailing and power catamarans, the objective is to cover nearly all or all of the energy needs on board. 

Once the energy is produced, we must then have the ability to store it.  So, for Lagoon owners to cruise with full peace of mind, we have selected, for each catamaran, high-capacity batteries.

Their clever management optimizes the charge and extends their lifespan.

 

Did You Know ?

The largest Lagoon catamarans, such as the Eighty 2 and Eighty 3, integrate solar panels in the Bimini and coachroof:  combined with lithium batteries, they maximize the available energy reserves on board.


Reliable Generators for Passagemaking

When making oceanic crossings and when needs exceed solar energy production capacity – for example, to run air conditioning aboard a catamaran while cruising in the tropics, or to run other equipment that is high in energy consumption – a generator can be used instead.

This enables you to maintain a high level of comfort on board, even while sailing on long passages.  Electricity is provided continuously, without ever having to worry about remaining stores!
 

Would you also like to achieve energy autonomy?  

Aboard Lagoon catamarans, generators are offered as an option, with capacity adapted to the owner’s cruising plans and with the configuration of their catamaran.

 

Turbines to Harness Wind Power

Some Lagoon owners use a hydrogenerator to produce their own energy from the force of the sea.  Aboard sailboats and catamarans, it is often common to count on the wind, by installing a wind turbine.

Within the framework of our sustainable innovation initiative, and our commitment pour la protection of the environment, we tested the integration of a wind turbine aboard a Lagoon 51

Thus, we can confirm the interest of this solution aboard a Lagoon catamaran, and in particular if you favor windier cruising areas, and if you wish to stay for multiple days at a paradisiacal anchorage!

Freshwater Aboard a Catamaran:  Making, Storing, and Managing Its Consumption

When the cruise is extended or the number of people on board increases, freshwater management also becomes an important point.

The ideal is to benefit from storage tanks with sufficient capacity, and achieve autonomy for the catamaran, or self-sufficiency. Keep an eye on the water consumption of the crew to always cruise in peace and comfort!

 

Storing Water Aboard Lagoon Catamarans

The freshwater tanks aboard the Lagoon catamarans provide a capacity of up to 300 liters aboard the Lagoon 38, the Lagoon 42 Millenium, and the Lagoon 43 – and up to a ton aboard the Lagoon Sixty 5, the Lagoon Eighty 2, and Lagoon Sixty 7.  

The largest Lagoon model, the Eighty 3, features 2 tanks with a total capacity of 1,600 liters of water.

To ensure optimal water quality, and to enable crews to drink water directly from the faucet, Lagoon has been the first catamaran builder to integrate the Oji Nautic 01 filtration system by UVOJI into a production series. On 12 volts, this system purifies water with help from UV-C rays, eliminating bacteria and viruses without the addition of chemical products. 

This technological advance reduces the necessity, on a cruise, to transport bottles and jugs of water:  within the space of a long-distance cruise, this contributes to the overall comfort on board, frees up space, and helps limit plastic waste… another action, on our part, to respect nature and the environment!
 

 

A Watermaker for Cruising with Full Autonomy

Water storage volumes aboard our catamarans already enable you to cruise for multiple weeks autonomously.  But to visit any destination without concern, we also equip Lagoons with a watermaker.

This device transforms seawater into freshwater, with an inverse osmosis filtration system.

Instead of limiting water stocked on board at departure, a watermaker enables you to continuously renew your reserves, eliminating the need to dock to restock water.

On an extended cruise, with regular maintenance and operation in keeping with the recommendations of our shipyard, the system proves very reliable and enables you to remain at sea longer.

Production capacities vary according to models and configurations:  depending on whether they run on “eco” mode or at full power, compact watermakers can produce from 60 to 90 liters of water per hour.

Larger appliances can achieve a production of 250 to 300 liters per hour.

Along with Equipment… Best Practices

Lastly, consider that the autonomy of a catamaran does not depend solely on the equipment installed:  it also depends on the crew’s capacity to pay attention to their consumption, and to adopt simple best practices to conserve resources.

Aboard our latest models, the management of fuel, water, and energy is integrated into a centralized control panel.  With this, it is possible to visualize production, consumption, and the status of battery charge in real time, and to plan for the production of fresh water in function with your needs.

Regular maintenance of these systems is another key factor:  remember to check the condition of the solar panels, to clean the filters in your watermaker, to test your generator, and to monitor your batteries to ensure that you are always cruising in the best conditions!
