Hans Unkles, a Scottish fisherman from Tayvallich, has become a pioneer in sustainable fishing with the Lorna Jane, the UK's first fully approved electric commercial fishing vessel. Driven by a passion for both fishing and renewable energy, Hans converted his 6.4-meter lobster potting boat to solar power, setting a new course for the industry.
Fueled by the Sun
The Lorna Jane's journey began with a retrofit. Previously reliant on diesel fuel, Hans replaced the engine with a 10kW electric motor powered by a bank of 4 x 460W bifacial solar panels. These clever panels capture sunlight from both above and below, maximizing efficiency. On sunny days, the boat charges itself while in use, and during calmer periods, the batteries can reach up to 90% charge.
Silent Running, Brighter Future
The switch to solar has brought several benefits. The most noticeable change is the peaceful operation. Hans now enjoys the tranquility of gliding through the water without the noise and fumes of a diesel engine. Additionally, maintenance costs are expected to decrease significantly due to the elimination of engine parts prone to wear and tear.
Embracing Challenges
While the conversion was a success, it wasn't without hurdles. The process took eight months, involving extensive modifications like raising the deck and building a new wheelhouse. Obtaining the necessary permits also presented challenges, requiring collaboration with the MCA (Maritime and Coastguard Agency). The biggest hurdle, however, was financial. The conversion cost was significant, highlighting the economic challenges of transitioning the fishing industry to clean energy.
Looking Ahead: A Collaborative Effort
The Lorna Jane's success story paves the way for a more sustainable future for fishing. However, widespread adoption requires collaboration. Upgrading ports with shore-side charging facilities and providing training programs for fishermen to maintain electric vessels are crucial steps. Additionally, financial incentives can encourage wider participation.
A Model for Smaller Boats
The Lorna Jane's size and function make it a perfect model for smaller inshore fishing boats that rely on static gear. With thousands of such vessels operating in the UK, solar power offers a promising solution for a cleaner and quieter future at sea.
Hans Unkles's journey with the Lorna Jane is an inspiration for the fishing industry. It demonstrates the potential of solar power and the importance of innovation for a sustainable future. By working together, fishermen, policymakers, and the public can ensure a healthy ocean and a thriving fishing industry for generations to come.
