In 2026, the risk of seasickness on a Greek ferry depends heavily on the type of vessel and the specific "Meltemi" wind conditions in the Aegean. The large, slow Blue Star-style conventional ferries are massive and equipped with advanced stabilizers; they are very stable even in moderate chop and are the best choice for those prone to motion sickness. Conversely, the high-speed "Seajets" catamarans and smaller hydrofoils are much more susceptible to the "pitch and roll" of the waves. Because these vessels travel at high speeds on top of the water, they can feel like a "bumpy ride" in even mild winds, which often leads to passengers feeling unwell. In 2026, seasoned travelers recommend taking a proactive dose of Dramamine (or the local Greek equivalent, Emetostop) at least 30 minutes before boarding. To stay stable, try to find a seat in the center of the ship on a lower deck, as this is the "pivot point" where the vessel's movement is the least pronounced.
