Poseidon Expeditions has entered into an agreement with shipowner SunStone Ships to extend the charter of the 114-passenger expedition ship Sea Spirit for two years.
The charter contract renewal means the ship will continue sailing under the Poseidon Expeditions banner until May 2024.
Sea Spirit will continue to spend each year between the two polar regions, in Antarctica and the Southern Ocean from late October through mid-March and then in the sub-Arctic and Arctic regions of the British Isles, Svalbard, Franz Josef Land, and Greenland from mid-May through September.
