Launched in 1991 and last extensively refurbished in 2017, the Sea Spirit is a highly versatile and ice-strengthened expedition vessel operated by Poseidon Expeditions. Designed for global navigation, the ship carries only 114 guests across 54 spacious suites and staterooms, making it one of the most intimate expedition ships operating in polar regions. Its compact size and 1A ice rating allow it to reach remote bays and narrow channels inaccessible to larger cruise liners, offering genuine, immersive exploration experiences in the Arctic and Antarctic. The Sea Spirit is focused entirely on discovery and comfort. 

It features a fleet of 10 Zodiacs for frequent, guided landings and excursions, a dedicated expedition team of expert naturalists, and a spacious observation lounge with panoramic views. Onboard amenities include a restaurant with unreserved seating, a bar and lounge, a library, a small fitness center, and a hot tub on the top deck for scenic relaxation amidst icy landscapes. The atmosphere is casual and educational, appealing to adventurous travelers who prioritize destination immersion and expert guidance over formal luxury. The Sea Spirit is a premier choice for those seeking a true polar adventure in a comfortable and friendly environment.
