Improve your green yacht charter credentials and get ready for the summer season by choosing one of Boatbookings’ many catamarans.

With the approaching summer season, Boatbookings discusses why chartering a catamaran is better for the health of our oceans and picks out some favourite, more sustainable options.

Catamarans continue to become increasingly popular choices for yacht charters. It is no wonder why – a catamaran provides so many benefits.

Whether it be crewed or bareboat, power or sail, you can enjoy their voluminous open-plan living and comfortable accommodation areas, their increased stability, and smoother cruising to that of a monohull.

Recent years have seen the multihull charter market evolving with its offerings, and most importantly, they highlight a significant move toward a greener and low-carbon agenda. We take a look at the ways they are better for our oceans.

Improved efficiency

The efficient hull design of a catamaran drastically reduces its resistance through the water, improving fuel efficiency. Boasting lighter hulls, they also have a lower displacement than monohulls. Power catamarans have a lower overall fuel burn and a steadier rise in speed while sailing catamarans can combine this advantage with nature’s wind power.

Fewer emissions

With overall reduced fuel consumption, there will be fewer emissions into our atmosphere; therefore, a catamaran will boast a lower carbon footprint. The benefit of a sailing catamaran is the overall fuel reduction, lessening emissions even more so than a power catamaran. Our emissions calculator can determine the exact footprint of any charter yacht.

Reduced impact

Another characteristic of a catamaran is its shallow draft, resulting in less impact on marine life while enabling more choices for better anchorages. With more out of the water, they have less disruption of the area’s marine ecology and the added benefit of less vibration and, therefore, noise. Their drafts also make them popular for specific cruising itineraries, such as the Bahamas and the BVIs.

Renewable opportunities

The wider beam of a catamaran provides more space for renewable energy alternatives. Their exterior can be outfitted with solar panels, perfect for soaking up the Caribbean and Pacific sunshine while also enabling the yacht to operate on less power from the generators and engines. There are also plenty of catamarans that run off electric power, reducing the reliance on fossil fuels.

Choose a greener catamaran today

Catamarans are part of a fast-growing segment of the charter industry. One that, thanks to innovative technology, is ever-evolving and improving its sustainability credentials.

Today there is a vast selection of eco-friendly catamarans that run on wind, solar, batteries and electric motors. As well as these greener technologies, many catamaran builders, such as Sunreef, implement a holistic sustainability process, using naturally-sourced materials throughout the build.

Boatbookings offers some of the best, greener catamaran options available for charter:

Sunreef, E Supercat 60:

This crewed Sunreef sailing catamaran, with nearly zero carbon emissions, boasts electric motors and rechargeable batteries while sailing; her eco-electric propulsion enables six hours of electric cruising.

Silent 64:

This Silent 64 power catamaran results in cleaner, electric cruising with zero emissions.

Lagoon 420:

This bareboat Lagoon 420 catamaran offers low fuel consumption and minimal emissions through her two electric motors and power by two sets of six batteries.

Fountaine Pajot, Aura 51:

This Fountaine Pajot 51 bareboat catamaran offers maximum space, that doubles up to provide renewable energy through its integrated solar panels.

With our oceans facing increasing environmental pressures, considering your next choice when chartering is more important than ever. Not only do catamarans offer a range of benefits, but they are also better for our oceans.

Hydrotreated Vegetable Oil produces dramatically fewer emissions than diesel

Yacht carbon emissions are a pressing issue in the yachting industry, and for good reasons, but what are the alternatives? Boatbookings begins to explore this topic as the industry accelerates its environmental agenda.

Ahead of the 33rd MYBA Charter show from 24th – 27th April in Barcelona, we take a look at the findings from the most recent MYBA environmental committee’s AGM report. The report discusses the immediate need for a fuel alternative and the role of HVO (Hydrotreated Vegetable Oil) fuel in moving toward net zero.

The emission problem

The average person produces around 7 tonnes of C02 annually. Considering that statistic, one litre of diesel creates about 3 KG of C02 in the atmosphere; according to the report, if “a big yacht consumes 60,000 litres per week on charter, this is 180 metric tons of C02.”

Given these statistics, it is no wonder that the industry’s future is steeped in a climate-conscious effort to pave the way toward a fossil fuel-free future. While there may be multiple challenges to fully decarbonizing the industry, there are also equal amounts of hope from innovative technologies and fast-developing hybrid and electrical solutions.

HVO; An alternative?

But how do we green the diesel-driven boats that are currently in our fleets? Experts believe HVO is the most viable alternative because there is no need to modify existing engines or generators.

Originally the first-generation biofuel, FAME (Fatty Acid Methyl Esters), hailed a bad reputation. This was mainly due to FAME’s oxidation and affinity to water, leading to a significant risk of microbial growth. But HVO’s chemical makup, as well as storage stability, is similar to that of fossil fuels. Hence it offers a possible direct replacement, meaning that all yachts, not just retrofitted ones, can reduce their emissions immediately.

So what exactly is HVO? It is made by using recycled sunflower oil. First, it undergoes hydro-treatment at high temperatures and pressures, where hydrogen is added to remove the oxygen. There are claims that it offers a 90% reduction in C02 emissions on the basis that it is made from recycled oil – having already made its environmental impact.

Who uses and supplies it?

Regarding the usage, Rolls Royce and MTU endorse HVO and have been testing their engines with it for a long time. As a tangible example, the charter yacht Lammouche has divulged its use of HVO fuel, which they source from Fioul83.

The short-term challenges of HVO have focussed on the availability, production, and higher cost compared to diesel. However, the report outlines that “yachts can buy it for a premium of about 35 cents a litre for pure HVO.”

In terms of supply, currently the best supplier is the Finland-based Neste, producing HVO with complete transparency – they are consistently ranked among the 100 most sustainable companies in the world. Although Neste is not yet “geared up to supply yachting, while aviation and ground-transport sectors are its primary consumers.”

The report further reveals solutions through Neste’s distribution partners, a French company Altens and their partnership with Monaco-based sustainable fuel suppliers Romano Energy. Although they have only delivered to 18 (smaller) boats so far, the future holds lots of possibilities.

Choose a lower-carbon yacht

What is clear is that to reach net zero, the industry needs to burn less conventional fuel. Recent years have seen various alternatives out there, such as electric/battery yachts – each with pros and cons. Alongside alternatives, the report urges people to use tools to measure C02 to measure and reduce emissions. You can use our emissions calculator to determine your footprint based on distance and fuel consumed per mile or kilometer.

We are always keen to share our recommendations for charter yachts that hail lower carbon emissions. The Boatbookings team will be present at the Barcelona MYBA show and look forward to discussing this topic and the industry’s newest sustainable innovations for the charter fleet.
