Sea Spirit
What's Sea Spirit like?
Small-ship polar expeditions focused on Zodiac landings and time ashore in Antarctica and the Arctic, for travelers prioritizing wildlife and landscapes over onboard amenities.
- Single small ship: The line's current ship, the 114-passenger, ice-strengthened Sea Spirit, keeps Zodiac landings quick to organize.
- Landing-centered days: Expect roughly two Zodiac outings daily, weather permitting, with lectures aboard; kayaking and camping are paid add-ons.
Worth knowing: Mandatory travel insurance needs at least $200,000 emergency medical cover; flights and gratuities are extra, so add these to the fare.
Style notes describe Poseidon Expeditions in general, not this ship specifically.
