Sylvia Earle

What is the Sylvia Earle?

The Sylvia Earle is the second of Aurora Expeditions' three purpose-built small expedition ships: a 104.4 m (343 ft) ship with an X-BOW hull that takes at most 130 guests on polar voyages.¹² It was built at the CMHI shipyard in Haimen, China, for the shipowner SunStone, and the final delivery documents were signed on October 21, 2022.⁴ SunStone still owns it and has it on long-term, year-round charter to Aurora.² Its inaugural voyage was scheduled to leave Ushuaia for Antarctica on December 10, 2022.⁴

The ship belongs to SunStone's Infinity class. Ulstein designed the exterior and Tomas Tillberg Design the interiors.⁴³ In Aurora's fleet its sisters are the Greg Mortimer (2019), the first passenger ship with an Ulstein X-BOW, and the Douglas Mawson (2025).⁵

Who is the Sylvia Earle ship named after?

It is named after Dr. Sylvia Earle, the marine biologist, oceanographer and explorer.¹ Mission Blue, the ocean conservation group she founded, describes her as a National Geographic Society Explorer in Residence, a former Chief Scientist of NOAA and the first "Hero for the Planet" named by Time magazine. It adds that she has led more than 100 expeditions, logged more than 7,000 hours underwater, led the first team of women aquanauts in 1970 and set a record for a solo dive to about 3,300 ft (1,000 m).⁶ Public decks on board are named for her and for six other women in conservation: Dr. Carden Wallace, Joanna Ruxton, Sharon Kwok, Bernadette Demientieff, Dr. Asha de Vos and Hanli Prinsloo.¹

How big is the Sylvia Earle, and what are its specs?

The Sylvia Earle is 104.4 m (343 ft) long, 18.4 m (60 ft) wide and 8,076 gross tons, with 71 cabins on 8 decks.¹² Aurora and the ship's owner publish these figures:

The passenger figures differ because they count different things. 130 is Aurora's cap on its polar expeditions, 144 is the number of passenger beds the owner lists, and Ulstein's launch story said the ship was designed for an average of 132 passengers per voyage.¹²⁴

The two ice labels come from different rating schemes rather than contradicting each other. 1A is a Finnish-Swedish ice-class notation, while PC6 is one of the seven IACS polar classes, and Ship Technology describes Polar Class 6 as equivalent to the Finnish-Swedish notation 1A Super.³¹²⁵ A ship can hold both: Quark Expeditions lists Ocean Explorer, another SunStone Infinity-class ship, as 1A and PC6.²⁹³⁰ Polar Class 6 is the second-lowest of the seven polar classes: it covers summer and autumn operation in medium first-year ice.²⁵ That is the same class as Oceanwide Expeditions' Hondius; Lindblad Expeditions' National Geographic Endurance is one step higher, at PC5.²¹²²

How does a 130-passenger ship affect landings in Antarctica?

It means a full ship can put everyone ashore in two groups of 100 or fewer. IAATO, the Antarctic tour operators' association, allows no more than 100 visitors ashore at one site at a time (fewer where a site's guideline sets a lower cap), one guiding staff member for every 20 visitors, and one ship at a site at a time.⁷²⁷ Ships with 201 to 500 passengers face extra restrictions on the time and place of their landings; with 130 guests, the Sylvia Earle sits in IAATO's 13 to 200 passenger category and avoids them.⁷

The published Antarctic Treaty site guidelines matter even more. Of the 45 the Treaty Secretariat publishes, 11 admit only ships carrying 200 passengers or fewer, among them Penguin Island, the Aitcho Islands, Hannah Point, Paulet Island and Baily Head on Deception Island.²⁷ At 130 guests the Sylvia Earle qualifies for all of them. Viking's Viking Octantis, listed by IAATO at 378 passengers, is shut out of those 11 and needs at least four rotations at a 100-person site (our arithmetic).³²

Aurora says its expedition team works at a staff-to-guest ratio of about 1:7.⁸

Is the Sylvia Earle stable in the Drake Passage?

No ship makes the Drake Passage smooth, but the Sylvia Earle has both an X-BOW and stabilizers that work at anchor. Ulstein, which owns the X-BOW design, says the inverted bow gives a gentler wave entry, less slamming and less pitching.²⁴ The owner lists zero-speed stabilization, and Aurora says the bow "cuts through the swell for a smoother transit."³¹ These are the builder's and the operator's claims; we found no independent measurements comparing its motion with other ships.

If seasickness is your main worry, compare the crossing options in our fly or sail the Drake guide. Of the ship's 2026-27 Antarctic departures listed below, only Wild Antarctica skips one crossing, by flying from Punta Arenas to King George Island.¹⁵

What cabins does the Sylvia Earle have, and what do they cost?

The Sylvia Earle has 71 cabins in 11 categories, from two porthole triples on Deck 3 to one 472 ft² (43.9 m²) Captain's Suite.¹ Every category except the triples and the Deck 7 Aurora Stateroom Superiors (which have French balconies) has a private balcony.¹ Prices below are for the December 29, 2026 Spirit of Antarctica departure, which showed no discounts, per person as listed on October 14, 2026.¹⁰

On that departure every cabin below the Balcony Stateroom Superior was already sold out.¹⁰ The ten solo cabins cost the same as one person's share of the matching twin balcony cabin, so they carry no single supplement; taking a twin cabin alone cost $32,543 in the Aurora Stateroom Superior, half again the shared price.¹⁰⁸ Discounts do not always reach the solo cabins: on the March 13, 2027 Whale Migration departure a Balcony Category C solo cabin was $18,595, against $15,806 per person for the discounted twin.¹⁴

Fares differ by voyage and date. The same Aurora Stateroom Superior was $16,646 per person on the 14-day Antarctica Active departure of November 24, 2026 (sold out), after a "save up to 10%" offer, and Aurora's offers page calls its current savings of up to 35% available "for a limited time."¹¹²⁶ Junior and Captain's Suite guests get binoculars, a stocked minibar, champagne and crew gratuities included.¹¹⁰

Is a balcony worth it on the Sylvia Earle?

On this ship a balcony costs little extra, so for most couples it is worth it. On the December 29, 2026 departure the cheapest private balcony (Balcony Stateroom Category C, $22,295) was $600 per person more than the French-balcony Aurora Stateroom Superior ($21,695).¹⁰ Because nearly every cabin has one, the real choice is size: Category A cabins are up to 309 ft² (28.7 m²) against 265 ft² (24.6 m²) for Category C.¹ The two triples on Deck 3 trade a porthole for the lowest fare and a short walk to the mudroom and Zodiac platforms.¹ Our Antarctica cruise balcony guide covers the trade-off across ships.

What activities can you do from the Sylvia Earle?

Zodiac cruises, landings and guided walks are included on every voyage; camping, kayaking, snowshoeing, snorkeling, scuba diving and ski touring are paid add-ons.¹⁰ The exception is Antarctica Active, which includes paddling, camping, snowshoeing and snorkeling in the fare.¹¹ Aurora's published add-on prices for its 2026-27 Antarctic voyages, per person:¹⁰

On the Svalbard voyages, sea kayaking is listed at $630 on the 8-day Realm of the Ice Bear and $780 on the 11-day Svalbard Odyssey.¹⁷¹⁶ The ship was laid out for these activities: a mudroom with individual lockers and drying areas for dry suits and wetsuits, four Zodiac doors and an activity launching platform.¹ It also has a Citizen Science Center, a lecture theater, a heated pool, two Jacuzzis, a sauna and a gym.¹ Aurora says it aims to offer a polar plunge on every suitable voyage, weather permitting.⁸

What is included in a Sylvia Earle fare?

Aurora's Antarctic fares include the bar: from the 2026-27 Antarctic season, premium spirits, cocktails, beer and wine are included, along with all meals, Starlink Wi-Fi, a 3-in-1 polar jacket, Muck boots on loan, landing fees and one pre-voyage hotel night on all Antarctic voyages.⁹ The ship's doctor is free for an initial consultation.⁹

Not included: flights to Ushuaia, travel insurance (which must cover medical evacuation), and a gratuity of $20 per person per day that Aurora adds to your onboard account; you can remove or change it, and the two suite categories include a crew gratuity of $15 per person per day instead.⁸¹⁰ Our Antarctica trip cost guide adds these up.

Where does the Sylvia Earle sail in 2026-27 and 2027?

The Sylvia Earle spends the austral summer on the Antarctic Peninsula from Ushuaia and the northern summer in Svalbard and Greenland. Its size counts in Svalbard too: since January 1, 2025, ships in Svalbard's protected areas may carry no more than 200 passengers.²⁸ These are its departures on the voyage pages we read on October 14, 2026, with the lowest per-person price shown for any cabin, discounts included:

The South Georgia voyage is the long one: three days at South Georgia and four on the Peninsula, after two days in the Falklands.¹³ Wild Antarctica's 2027 departure runs March 2 to 14 although Aurora lists the voyage at 11 days, so confirm the length before booking.¹⁵ The cheapest cabin still for sale on any of the ship's 2026-27 Antarctic departures was that $17,336 Wild Antarctica triple.¹⁵

How does the Sylvia Earle compare with similar ships?

It is a near twin of Aurora's Greg Mortimer and Douglas Mawson, which have more cabins but the same 130-guest cap on expeditions, and it is one of the smallest ships we cover. The table compares it with its Aurora sisters, Quark's Infinity-class Ocean Explorer and the nearest small-ship alternatives:

The three Aurora ships are all about 104 m (341 to 343 ft) long, cruise at 10 to 12 knots and take 130 guests on expeditions, so the choice between them comes down to dates and price rather than the ship.¹¹⁹²⁰ Pick Ultramarine for helicopter flights, National Geographic Endurance for the higher ice class, or the Sylvia Earle and its sisters for the smallest landing groups.

Who should book the Sylvia Earle?

Book it if you want the smallest practical landing groups, a balcony for little extra money, or add-on activities from camping to ski touring. Solo travelers do well here: ten balcony cabins carry no single supplement, though they may miss out on sale discounts.¹⁰⁸¹⁴ Look elsewhere if you want helicopters, a large suite inventory (there are five suites), or to fly both ways across the Drake, which none of its 2026-27 Antarctic departures does.
