Monaco Energy Boat Challenge bigger and better than ever for 2024

The eleventh edition of the Monaco Energy Boat Challenge (MEBC) takes place this week at the Yacht Club de Monaco (YCM) with the most ever student teams and commercial electric boat manufactures attending and an expanded programme of seminars and conferences, including the first Annual General Meeting of the recently formed International Electric Marine Association (IEMA).

50 student teams competing

There are 50 student teams competing in the Challenge, racing over three days in three classes: the Energy Class and Solar Class is comprised of student teams from 40 international universities, while the Open Sea Class has 13 commercial electric boats competing along with 3 student prototype boats in the SeaLab class.

2024 MEBC an electrifying success Part 1 – Open Sea Class
2024 MEBC an electrifying success Part II – Energy and Solar Class

On shore events taking place in the clubhouse include

  • a Job Forum for the students to meet with boat manufacturers and others in the electric propulsion sector
  • a two day conference covering the topic of alternative fuels and advanced state of the art technologies on day one with the fifth edition of hydrogen round table on day two
  • the MEBC e-Sport Championship where competitors choose the performance elements of their boat within a certain budget, then race on a virtual version of the MEBC course and
  • Tech Talks from each of the university teams where they present the details and research behind their boat projects to an international Jury during the Tech Talks. This year a new format is launched  with prizes for the best 6 projects in each category.

Monaco Energy Boat Challenge student teams from Italy and Greece celebrating

All of this is powered through an E-Dock lined with AC and DC chargers from Aqua superPower. The YCM was the site of the first installation in the world of the Aqua marine high speed charger and last year’s Challenge saw the first E-Dock for the Energy Boat Challenge. This year’s updated version enables fast and reliable charging for up to 20 electric boats concurrently.

There are flexible solar panels on the E-Dock’s roof, and there is also a floating prototype pontoon producing green hydrogen from renewable energy sources in Monaco. This project provides Type 4 cylinders of hydrogen to the teams using it in their propulsion systems, thanks to SBM Offshore and CTS (Composite Technical System). 

The number of student and commercial teams participating, the involvement of all the major players in the electric boat industry and larger yachting industry, the breadth of leading edge technologies presented both off and on shore – they are a vivid demonstration of how much the MEBC and electric boating have grown in the past decade.

Monaco Energy Boat Challenge started in 2014

In 2014 the MEBC was launched as a solar-boat-only competition for 23 teams from 10 countries. The next year saw the addition of the Offshore class and in 2018 the Energy Class was introduced followed by the Conference, Exhibition and Job Forum in 2019 along with first Monaco Hydrogen Round Table coinciding with 2 hydrogen boats competing in the Challenge.

Bernard d’Alessandri, YCM General Secretary says the Club’s ambition is to be a major player in the drive for sustainability and this meeting of many players is a key element of bringing about the environmental transition. “Faced with the climate emergency, it is imperative that living proof of progress replaces the promises” he states. “We want to demonstrate that the technology exists and is efficient. That is the raison d’être of the Monaco Energy Boat Challenge, which is positioning the Principality as a driving force for responsible yachting.”

The brochure and full programme of this year’s events can be viewed and downloaded through the link below, but here is a quick overview of what is happening through the week:

Energy Class

Monaco Energy Boat Challenge Energy Class boat

The Energy Class was launched by the YCM in 2018 to expand the student teams to universities that may hot have courses in naval architecture but have strong engineering programmes. The Yacht Club supplies the teams with the same design catamaran hull which the teams that outfit with their cockpit and the most efficient and durable propulsion system using renewable alternative energy sources limited to a given quantity of energy (max. 10kWh stored on board).

Some projects use battery electric propulsion, some use hydrogen cell or a combination of battery and cell, some augment their systems with solar power – the ingenuity and accomplishments of the students are impressive.

The boats house one pilot each and compete in three events: 

  • Slalom: Boats navigate a slalom course in the open waters just east of the YCM with the fastest times determining the winner (assuming all slalom gates are navigated).
  • Speed Record: Boats are timed over a 1 kilometre distance in the same waters, with the speed course inspired by the boundaries of the original 1904 course where the Yacht Club de Monaco hosted the first international powerboat contest.
  • Endurance Challenge: For the endurance challenge, boats race for as long as possible on the course to demonstrate their boats’ energy capabilities (with the course open for 4 hours).
  • Championship Race: This event takes place within the marina of the YCM. Two teams compete going opposite directions where they have to navigate an outer loop and inner loop and then come out of that course to go head to head for the final straightaway. This is a spectacularly entertaining ‘knockout’ event where all of the students gather to roar their encouragement and support.

Last year’s winner (and in 2022) was the Uniboat Solar Team from the Università di Bologna. Their solar-powered boat is a blend of academic excellence and innovation, with consecutive wins highlighting both their technical prowess and commitment to a greener maritime future.

This year they are joined by 17 other teams:

 – Polytechnique de Montréal
 – Pontifical Catholic University of Chile
 – University of Rijeka

Solar Class

MEBC Solar Class boat

The Solar Class competes in the same races as the Energy Class, but at different times.

The boats all have battery-electric propulsion systems with a full battery for the start of the race. The are allowed to harvest solar energy during the race – especially important in the Endurance challenge. The engineering challenge is to create as large a space as possible for solar panels and battery while also being conscious of the effect on the boats’ speed and manoeuvrability. Some teams have incorporated foiling technology.

Last year’s winner, the Sunflare Solar Team, has been participating in the MEBC since the first 2014 solar only event. They have a very hands-on approach to innovation, with the team prioritizing efficiency and weight reduction. Their motto is simple: for the best results, craft it yourself.

Open Sea Class and SeaLab Class

Candela C-7 competing in the 2023 Monaco Energy Boat Challenge

The Open Sea Class started life as the Offshore Class in 2018 and has evolved into the class for commercial electric boat entries and also prototypes from students and teams that want to develop their projects outside the strict rules of the Energy and Solar classes.

The boats compete in similar, but different events from the student teams.

  • Manoeuvrability Challenge: replaces the slalom event that Energy and Solar classes compete in. For the Open Sea and SeaLab boats, they are required to navigate a manoeuvrability  course set within the confines of the YCM marina, with a maximum speed of 3 knots (3.5 mph / 5.5 kmh)
  • In a sort of combination of the speed and endurance races, the Open Sea and SeaLab boats will participate in a 21 nautical mile round trip between Monaco and Cala del Forte in Ventimiglia, with timings for each leg. Contestants are allowed to recharge if needed, and the event also provides a platform for showcasing their innovative boats to the Italian audience.
