The Madleen—a diesel powered sail boat—is currently en route to Gaza as part of the Freedom Flotilla Coalition’s effort to deliver humanitarian aid and challenge the ongoing Israeli blockade. While the word “flotilla” typically refers to a group or fleet of ships operating together, this mission finds the Madleen sailing alone, with prominent climate activist Greta Thunberg onboard.
The boat is registered as Barcarole (MMSI: 232057367), a sailing vessel sailing under the flag of United Kingdom. Her length overall (LOA) is 18 meters and her width is 5 meters.
Though equipped with sails to reduce fuel use, the Madleen also depends on a diesel engine.
Still, the voyage raises questions for environmental advocates about issues like bilge discharge (are there composting toilets onboard?), fuel sourcing, and carbon offsetting—especially with a high-profile environmentalist onboard.
The current crew consists of 12 individuals from a range of countries and professional backgrounds. Notably: Greta Thunberg (Sweden) – Global climate activist, now expanding her focus to include humanitarian issues.
Liam Cunningham (Ireland) – Actor known for his role in Game of Thrones, and an advocate for refugee rights and humanitarian causes.
Rima Hassan (France) – Human rights lawyer and newly elected member of the European Parliament, known for her outspoken support for Palestinian rights. She has previously been denied entry to Israel over security concerns.
Other crew members include activists, journalists, and medical professionals from around the world—including one from Turkey, where press freedom remains a contentious issue. While the group is diverse, they are united in their mission to highlight what they describe as a worsening humanitarian crisis in Gaza.
The Madleen is reportedly carrying basic aid supplies, including baby formula, food staples, hygiene products, and medical equipment. Still, given the vessel’s limited cargo capacity, its humanitarian impact is likely to be symbolic rather than substantial. The mission is as much political as logistical, aimed at drawing attention to the blockade, which restricts the movement of goods and people in and out of Gaza.
Egypt, which also borders Gaza, reportedly charges refugees large sums—often around $5,000—for safe passage, limiting alternative escape routes for civilians.

Public reactions have been mixed. Some online voices have expressed harsh criticism and even hostility toward the voyage. Others see it as a legitimate and peaceful form of protest aimed at raising awareness.
The intersection of environmental and human rights activism is particularly visible in this mission. The coalition claims to minimize its environmental footprint using sails, yet questions remain about the broader sustainability and ethics of such journeys.

The use of flotillas to challenge the Gaza blockade has been done before, most notably the Mavi Marmara in 2010. That mission, organized by the Turkish NGO IHH, ended in violence when Israeli forces boarded the ship in international waters. Nine activists were killed, and a tenth died later from his injuries. Israel claimed self-defense, citing improvised weapons used by passengers that they found later. The IHH has faced allegations of ties to terrorist groups, which it denies. The event remains controversial and is cited by both sides of the debate as either a cautionary tale or a justification for resistance.
US Senator Lindsey Graham announced in a controversial post on X, “I hope Greta and her friends can swim.”
On X, the Maccabee Task Force wrote, “Greta Thunberg’s so-called “freedom flotilla” encapsulates the delusion and hypocrisy surrounding the Israel-Gaza war. This isn’t a humanitarian mission—it’s a Mediterranean leisure cruise.
“Participants are smiling, swimming, and filming TikTok videos. This is self-serving activism. And let’s be honest: she wouldn’t dare try this stunt anywhere near Hamas-controlled waters. She knows she’s safe because Israel has Hamas on the ropes. That’s what makes this spectacle possible. It’s not activism. Its performance. And it’s pathetic.”
Participants on the boat posted on X about a worrying drone circling overhead yesterday, “From Forensic Architecture: Helenic Coast Guard Heron drone was seen active close to your location a couple of hours ago – ADSB hasn’t updated assets location since 20:30 pm. It did a similar trajectory the last couple of days.”
It turned out to be Greek coast guard patrol drone doing routine surveillance.
Among the crew is Brazilian Thiago Ávila who supports “the resistance”. He met Hezbollah’s former leader Hassan Nasrallah in 2006 and also attended Nasrallah’s funeral in Beirut in February 2025. Here he is singing a “resistance” song aboard the boat, in a video posted to X. Hezbollah is considered a terror organization by the US, Canada and Europe, the Arab League, Japan etc.
Whether the Madleen’s voyage ends peacefully or is met with confrontation remains to be seen. What is clear is that such missions continue to stir international debate—not only about the politics of Gaza but also about the evolving roles of civil disobedience, humanitarian action, and environmental responsibility in an increasingly complex world.
While violence uprisings happen in the Middle East, there is little acceptance of peaceful protest, especially in Gaza. Before the October 7, 2023 attack on Israel, people in Gaza had tried to rise up against Hamas and were met with a fatal warning or their end.
Meanwhile the Freedom Flotilla has an excellent opportunity to shed a light on Libya’s human rights abuses as it sails by Libya, a country mired in instability and lawlessness over a decade after the fall of Muammar Gaddafi. Armed groups continue to operate with impunity, engaging in extrajudicial killings, kidnappings, and attacks on civilians.
Let us hope that this Gaza “flotilla of one” can offer more than just political controversy and instead deliver a message of unity, dignity, and peace for all people everywhere.
We are waiting for a response from Israel’s IDF on what Israel plans to do once Greta Thunberg enters its territory.
