Water is an essential building block of life that withholds environmental, societal, and economic value. It is also a vital resource that lies at the heart of sustainable yachting. Owners of eco yachts can take simple steps to cast a bigger impact towards water conservation. Better yet, there are innumerable ways to save water without compromising comfort onboard.

Eliminating Plastics

In today’s modern world, marine pollution caused due to chemicals and trash has emerged as a pressing issue. Nearly 80 percent of marine debris comes from land-based activities, the most problematic pollutant of which has been recognized as plastic waste. Be it caps or bottles, plastics take up to hundreds of years to decompose.

What is more that small organisms mistakenly feed onto these microplastics which eventually becomes a part of what humans eat since the microplastics migrates up the food chain when organisms are consumed by larger animals in the sea. In order to limit plastic use on board yachts, it is recommended to switch plastic containers out for reusable insulated glass bottles that can be refilled with recycled water.

Recycled Water

A smarter strategy to tackling yacht waste disposal is enhancing the capabilities onboard of producing freshwater using a watermaker and an advanced purification system. This feature purifies seawater into clean, drinkable water in a process called reverse osmosis, a technology that pushes water through a semi-permeable membrane to remove mineral chemicals, ions, and other contaminants from drinking water.

Using this technology, passengers and crew members onboard Sunreef Yachts’ sailing and power catamarans, enjoy unlimited access to fresh water while also actively reducing the consumption of single-use plastic bottles to a bare minimum and promoting self-sufficiency.

Reusing Rainwater

Sunreef Yachts Eco is developing a smart rainwater collection system onboard its eco yachts to save water for washing the decks, rinsing the water toys, and other human use. It is as simple as capturing rainwater by redirecting it from larger surfaces (i.e., the bimini roof) to holding tank. The harvested water may be filtered and pumped back to the appliances or heater tanks for domestic applications such as the sinks, showers, flushing toilets, and washing machines.

A rainwater collection system acts as an excellent backup source of water for emergencies. It is deemed environmentally responsible as it helps conserve water and promotes self-sufficiency. Additionally, this technology is inexpensive, easy to maintain, and flexible as it allows for expansion, relocation, and reconfiguration as needed. All in all, this system minimizes contributions to yacht water waste.

Lifestyle Alternations

However, it is without a doubt that simple lifestyle changes can also significantly impact water conservation levels. For example, reusing towels, rather than tossing them in the bin after each use significantly reduces consumption in laundry. Here are a few other ways to save water for a better tomorrow:

Frequently Asked Questions

Why do yachts store water?

Yachts have a freshwater storage tank that stores water suitable for drinking. However, in case of longer voyages, yachts are capable of recycling seawater through a process called reverse osmosis which pushes water through a semi-permeable membrane, purifying it of ions, minerals, and other pollutants.

What is rainwater harvesting system?

A rainwater harvesting or collection system collects and stores rainwater that falls atop the bimini. Filtering and treating this water allow for it to be used in different parts of the boat, such as for washing clothes, doing laundry, rinsing the deck or water toys, and bathing.
