A sailing boat that generates some of its power from the waves is being constructed in the Philippines.

The hybrid trimaran, which is currently being built by company Metallica Shipyard, uses multiple internal combustion engines for initial propulsion but switches to wave energy while cruising in open waters.

The trimaran transforms waves into energy through double-action hydraulic pumps integrated in its outriggers. As the pumps move through the waves, they generate electricity that provides auxiliary power to the vessel, which is driven primarily by a regular gasoline motor. The stronger the waves that the vessel encounters at sea, the more power will be produced.

The technology is expected to improve the vessel’s energy efficiency making it not only cost-efficient but also environment friendly.

A network of old cargo and passenger ships currently connects the many islands that make up the Visayas region in the central Philippines. While these vessels are crucial for moving goods and people, they have long been considered major polluters of this biodiverse region, and contributors to greenhouse gas emissions.

The marine engineer behind Metallica Shipyard, Jonathan Salvador believes that the hybrid trimaran will offer a green alternative in the maritime sector – significantly reducing pollution and greenhouse gas emissions.

Metallica Shipyard secured funding from the Philippines’ Department of Science and Technology (DOST) for the project and is currently being built in the province of Aklan.

Once operational, the hybrid trimaran is expected to be able to accommodate more than 100 passengers, four vans and 15 motorcycles.

Metallica Shipyard is planning to complete construction of the vessel by the end of 2020. A three-month trial where the hybrid trimaran will be tested out in Boracay, the most popular tourist island in the Philippines, is expeted early next year.
