In an announcement kept firmly under wraps until this year’s DEMA Show, Aggressor Adventures has unveiled the latest expansion to its global portfolio with the introduction of the Madagascar Aggressor, due to set sail on its maiden voyage on 6 June 2027.
The new liveaboard will operate in the waters surrounding Nosy Be and the archipelagos of north-western Madagascar, home to colourful coral reefs, dramatic underwater formations and an extraordinary diversity of marine life.
‘Madagascar represents exactly the kind of destination Aggressor was created to explore – remote, culturally distinctive and surrounded by extraordinary marine ecosystems,’ said Jay Roberts, CEO of Aggressor Adventures.
‘I am excited to welcome guests aboard the Madagascar Aggressor and introduce them to Nosy Be and archipelagos that relatively few divers have experienced.’
Designed to accommodate 24 guests, the Madagascar Aggressor will feature 12 staterooms across three decks, spacious indoor and outdoor gathering areas, and a sun deck with a hot tub for relaxing between dives, providing an intimate setting for exploring one of the Indian Ocean’s most distinctive diving regions.
Diverse diving and remarkable marine life

The waters of north-western Madagascar offer a variety of underwater environments, including coral gardens, gorgonian-covered reefs, pinnacles, drop-offs, arches and wrecks.
Divers may encounter humpback whales, whale sharks, reef sharks, rays, turtles, and large schools of tropical fish, including fusiliers, jacks, barracuda, batfish and surgeonfish.
The region also offers opportunities for underwater photographers to search for smaller marine life, including nudibranchs, leaf fish, scorpionfish, crocodile fish, moray eels and octopus.
The variety of habitats and marine species makes the area appealing to divers with a wide range of interests and experience.
Seasonal wildlife encounters

Madagascar’s marine life changes throughout the year, offering different highlights across the diving season.
From April to June, divers can enjoy reef exploration with opportunities to encounter turtles, schooling fish, rays and manta rays. Between June and November, migrating humpback whales pass through the region, and guests may observe them from the yacht or tenders and potentially hear their songs underwater.
Whale sharks gather in the waters surrounding Nosy Be between September and December each year, with the strongest period during October and November, offering opportunities for encounters alongside manta and mobula rays.
All wildlife encounters are subject to natural conditions and cannot be guaranteed. However, each departure offers the opportunity to explore Madagascar’s reefs, remote islands and diverse underwater ecosystems.
