At the Institut de Nàutica de Barcelona, we prepare students for the real world, which means tackling specific technical challenges that also have a positive environmental impact. One example is a project they recently completed: electrifying a traditional Mallorcan boat called El Pallus.
This small boat, with a fiberglass hull, was powered by an old gasoline engine. The aim of the project was to remove that engine and replace it with a fully electric propulsion system: a 3.5 kW inboard motor powered by a 48V lithium battery. A charger, a joystick control system, and a monitor to check the battery status at all times were also installed.
The students not only changed the motor, but also participated in the entire process: they designed and built the wooden supports to hold the motor and batteries, worked with fiberglass and resin to reinforce the structures, and adapted the interior of the boat so that everything would fit and be safe. They even sought practical solutions, such as making the battery support removable to facilitate maintenance.
All in all, it was a comprehensive experience in which they learned both technical and practical skills: from how an electric propulsion system works to the use of tools and materials commonly used in shipbuilding and repair.
These types of projects allow us to train professionals with up-to-date knowledge who are also aware of the need for cleaner and more efficient maritime transport.
