RMS St. Helena has one of the best backstories afloat. Built in the UK in 1989, she spent nearly three decades as a genuine Royal Mail Ship — the lifeline that carried mail, cargo, and passengers to St. Helena, one of the most remote inhabited islands on earth, until the island’s first airport retired her in 2018. After a stint supporting the Extreme E racing series, Terra Nova Expeditions chartered her, poured in a reported $10.8 million refit, and pointed her south.
The refit cut her capacity from 150 down to 98 guests, which tells you the priorities: more room, fewer people, and a 1C ice-strengthened hull built for remote coastlines. Onboard is all-inclusive in the truest sense — kayaking, camping, snowshoeing, the polar plunge, gratuities, and beer and wine at dinner are baked into one flat price — plus a working science lab, a gym and spa, two Jacuzzis, and a genuinely rare perk for solo travelers: single cabins at no supplement. On select departures you can add a day sail aboard the Icebird yacht for a closer look at the ice.
We’ll be straight about our vantage point: Terra Nova is a young line and St. Helena a freshly reimagined ship, so our read leans on her specs, her heritage, and the relationships behind the brand as much as on time aboard. But for travelers who want authentic expedition character over polished luxury, she’s one of the most intriguing ways to reach the ice. Worth stacking against the rest of the Antarctica fleet.

What makes RMS St. Helena the ship
All-Inclusive Dining
Flat-priced, no upsells
Hearty, expedition-style meals with beer, wine, and soda included at lunch and dinner, plus a daily happy hour. No extra upsells — it’s all folded into the flat fare.
Observation Lounges + Open Decks
Wildlife viewing from the warm side
Generous observation lounges and open decks built for wildlife viewing and big Antarctic panoramas. The social heart of the ship between landings, with sweeping views from the warm side of the glass.
Spa, Gym + Two Jacuzzis
Wellness for sea days and post-landing
The ship’s wellness corner: a spa for post-landing recovery, a gym for sea days, and two Jacuzzis for soaking in the polar air. Earned relaxation after a day on the ice.
Onboard Science Lab
Scientists in residence every sailing
A working science laboratory with researchers in residence all season. Guests can join citizen-science projects — real data collection that contributes to Antarctic research while you sail.
Icebird Sailing Yacht (Add-On)
Optional paid day sail on select departures
On select departures, St. Helena carries the Icebird — a 61-foot custom aluminium sailing yacht (Van de Stadt-designed, ice-strengthened for polar waters) you can board for an optional paid day sail. With a rigid inflatable, kayaks, skis, and dive gear in her aft garage, she brings a handful of guests closer to the ice and wildlife than any Zodiac can. It’s an extra-cost add-on, not a standalone voyage.
Onboard Medical Clinic
Doctor aboard every voyage
A medical clinic with a doctor aboard for every voyage — the reassurance you want when sailing to one of the most remote places on the planet.
