The future of coastal water boating is electric
Looking at the global trends and developments towards clean and environment friendly innovations, alternatives like solar electric propelled vessels could have the biggest growth potential in the near future! Although there seems to be enough awareness for electric alternatives in the automotive industry, the market of electric propelled vessels seems very much in its infancy.
The lack of real working alternatives for saltwater operations might have been the main reason why cities like Sydney, so far, have refrained from changing towards solar electric boats and ferries. For islands like Fiji, where boat transportation is the largest energy consumer with 58% compared to cars, buses and airplanes, sustainable alternatives on the water could have an enormous impact in the future.

A sustainable solution born in New Zealand
The Dutch company Soel Yachts is determined to change the boating industry by addressing sustainable sea transportation. Together with their partner Naval DC, Soel Yachts puts their 11 years of solar electric naval architecture experience into the SoelCat 12, a fully sustainable vessel proven for saltwater operations.
This week the solar electric 16-person catamaran, built in New Zealand, will be launched in Auckland. Energy autonomous and ready for all water taxi services, dive operations and reef excursions, “the SoelCat 12 reduces all disturbing sound and CO2 emissions in our harbours, lagoons and oceans”, proudly emphasises Joep Koster, co-founder of Soel Yachts.
Smart integration for higher performances
Soel Yachts believes that a solar electric boat needs to be an equally workable solution, addressing efficiency and performance. The SoelCat 12 therefore fits its purpose, or better said: it is designed for it in every single aspect. From the highly efficient hull lines to the matched and turnkey integrated solar electric propulsion system. It is basically the same approach Tesla is using for its cars: “one cannot just take any existing hull shape, add an electric motor and hope that it achieves a range of 150nm.” David Czap, the system integrator explains: “efficient electric propulsion requires an entirely different approach from nowadays technologies and practices. Therefore, all our vessels are integrally designed from start to finish for and with electric propulsion and the specific duty cycle in mind.”
With an installed battery capacity of 2 x 60 kWh, the SoelCat 12 standard operational profile is set to a cruising speed of 8 knots with a range of 6 hours solely running on battery power and a maximum speed of 14 knots. Once the sun starts to shine the vessel’s cruising speed of 8 knots is prolonged to 7.5 hours. Lowering the speed to the so-called ‘break-even speed’ at 6 knots results in a 24-hour range and this is even throughout the night when there is no energy harvest from the solar array.
Power your house with the SoelCat 12
During downtime, the vessel turns into a mobile power station, which is able to supply up to 15kVA for land based facilities. This means that solar catamaran is capable of providing energy for up to five households, even at the most remote places. For the first time communities in the Pacific, nature reserves and water bound resort can turn into self-sufficient eco-destinations, producing their own clean energy on the water and even use it on the land.
Monitor the SoelCat 12 with your iPad
Providing the passengers with a simple and easy to understand real time insight into the SoelCat 12’s systems is very important to Soel Yachts and Naval DC. The Naval UI monitoring, alarm & control system keeps all passengers on board informed about the most important system data, which makes the energy flows on board really easy to understand (just like in a Tesla) and thus educates people to drive the vessel more energy aware. All it takes is to connect your smart device (iPhone, iPad) to the SoelCat 12’s guest Wi-Fi. And while the captain can control the lights and various other systems via the Naval UI, guests on board are invited to connect with their smartphone to the vessel’s sound system and play their favourite music, wirelessly. The Naval UI also provides remote monitoring capabilities, so Naval DC can assist in providing system services, remotely.
Transportation made easy
The SoelCat 12 is the first viable solution for solar electric sailing available for a worldwide market. Engineered and designed as a smart modular vessel, the solar electric yacht can be disassembled and transported to any location at very low rates via two 40ft containers. This vessel not only allows for quieter, more pleasant rides and tours, it also provides comfort and higher speeds, without having to make any compromises on board!
Free test drives in Auckland
Join the experience and register now with Soel Yachts for test drives in Auckland. On Sunday, June 25th the SoelCat 12 will be open for the public to come on board in the Viaduct Harbour to join the crew for a free solar electric cruise between 11am and 2pm!
More information can be found on www.soelyachts.com or on the Facebook event page.
If you are not in Auckland NZ or cannot make it on June 25th, don't worry, you can always rent an eco-friendly boat or yacht through our newish boat rental platform: weareonaboat.com
