Why we picked it
Sea Spirit sits in a useful gap between stripped-back expedition ships and larger modern vessels. She is small enough to run a nimble operation, yet her cabins are unusually spacious and the fare includes the pre-voyage hotel, house drinks, Wi-Fi, parka and boots.
Travellers who value landing efficiency, a friendly 114-guest atmosphere and an expedition-first programme more than contemporary ship design.
When the kayaking group operates separately, the remaining guests can generally land as one group rather than working through the rotations common on larger ships.
Sea Spirit is an older, traditional ship. Suites are spacious and comfortable, but the design is less modern than newer X-BOW vessels such as Ocean Albatros or Ocean Victory.
Why Sea Spirit’s size matters
Poseidon’s short film explains how a 114-guest ship changes the rhythm of an expedition—from landing logistics to the atmosphere aboard.
A classic Peninsula route, properly paced
This itinerary allocates five flexible days to the South Shetland Islands and Antarctic Peninsula. The expedition leader chooses landings and Zodiac cruises around weather, ice and wildlife rather than following a rigid port schedule.
The route normally includes penguin colonies, glacier-lined bays, iceberg-filled channels and opportunities to look for seals and whales. Hiking and photography guidance are part of the core programme; kayaking and camping are limited optional activities and differ by departure.
The EA insight
The advantage here is operational scale, not a promise of more landings. Antarctica controls the schedule. Sea Spirit simply gives the team fewer passenger movements to manage when a short weather window appears.
A typical day in Antarctica
Poseidon’s expedition team explains how a day unfolds aboard Sea Spirit—from the morning briefing and first Zodiac launch to landings, wildlife encounters and the evening recap.
Day-by-day plan
The precise sites remain flexible. This is the usual structure rather than a guaranteed landing list.
Arrive in Ushuaia
Poseidon meets guests at Ushuaia Airport on the scheduled arrival day and transfers the group to the included pre-voyage hotel. The afternoon is free, followed by the operator’s practical embarkation arrangements.
Embark Sea Spirit
A group transfer connects the hotel and ship. After embarkation, the team completes safety briefings and begins the journey through the Beagle Channel.
Cross the Drake Passage
Lectures, wildlife watching and biosecurity preparation fill the crossing. Wandering albatrosses, petrels and the transition across the Antarctic Convergence provide the first signs of the Southern Ocean ecosystem.
South Shetlands and Antarctic Peninsula
Five days are available for landings, Zodiac cruising, wildlife encounters and hikes. Possible areas include the South Shetland Islands, Gerlache Strait and the Lemaire Channel, but the captain and expedition leader continually adjust the route.

Zodiac landingsReturn across the Drake
The ship turns north for final lectures, wildlife watches and the expedition recap.
Disembark in Ushuaia
A group transfer is included to Ushuaia Airport or a central location immediately after disembarkation. Poseidon recommends booking flights from noon or later.
A small expedition community
One of Sea Spirit’s quieter advantages is the atmosphere created by travelling with 114 guests. The expedition team becomes familiar, briefings feel personal and the ship develops a genuine group rhythm over twelve days.
Why it matters
The ship’s size affects more than landing logistics. It also shapes how readily guests, guides and crew get to know one another during the voyage.
The people who shape the voyage
Poseidon’s expedition leaders introduce their polar backgrounds, what draws them back to Antarctica and the onboard rhythm they create for guests.
Sea Spirit and her cabins
Sea Spirit carries 114 guests in suite-style accommodation. The ship has an ice-strengthened hull, retractable fin stabilisers, a fleet of Zodiacs and larger cabins than many expedition ships of a similar size.

Poseidon’s Request-Share guarantee
This is one of the clearest reasons to shortlist Poseidon. A solo traveller can request a same-gender cabin mate in eligible categories and pay the normal shared per-person fare. If Poseidon cannot provide a match, it waives the single supplement rather than moving the traveller to a solo price.
Available in Triple, Main Deck, Classic and Superior Suites, subject to the operator’s current terms.
Ask EA to confirm sole-occupancy availability and the current single supplement for Main Deck, Classic and Superior Suites.
Ask EA for a current private-cabin quote for Deluxe, Premium and Owner’s Suites.
Travelling as two singles?
If two friends already intend to share, we ask Poseidon to confirm the correct twin-bed setup and cabin category rather than relying on the matching programme. If each wants a private cabin, we compare dedicated Single Suites with sole occupancy in eligible twin categories.
