EYOS · Explorer Yacht Inputs for a Newbuild

The Antarctic Peninsula

11 Dec – 16 Jan (mid-summer) / 1,931 NM / Two back-to-back charters / Fly in & out via Antarctica

Two explorer yachts at the fast-ice edge, Antarctic Peninsula

Two explorer vessels working the fast-ice edge. Antarctic Peninsula.

The Antarctic Peninsula begins 520nm south of South America and spans 500nm south to the main body of the continent. The Peninsula offers spectacular scenery ("…like Switzerland emerging from the sea"), incredible wildlife and sheltered coastal cruising conditions. 98% of EYOS clients elect to 'skip the Drake' and fly across from Punta Arenas, Chile, direct to King George Island in Antarctica. This allows the yacht to cross the Drake ahead of the guests and within a weather window that is optimal. By utilising this intercontinental air link, EYOS is able to fly guests in and out on multiple expeditions before the yacht needs to return to South America to refuel.

Peak summer months are December to March, with ice gradually disappearing during this period. Vessels with light or zero ice capability are limited to the more northern latitudes and a shorter season (Jan/Feb), while those with ice capability are able to explore the Peninsula in its entirety, and extend their cruising to encompass the entire summer.

To the East of the Peninsula is the fabled Weddell Sea, made famous by the exploits of Shackleton. The Weddell Sea typically retains significant ice all through the summer and is better suited to vessels with ice capability. It is the only destination on this side of Antarctica where an Emperor penguin may be sighted.

The Weddell SeaThis area offers a wide range of ice conditions, including multi-year sea ice, first-year sea ice, and glacial ice. One of the defining features of the Weddell Sea is its large tabular icebergs. Ice conditions can be challenging, and any vessel entering the Weddell Sea will carefully assess weather forecasts and ice charts before committing. As a result, vessels operating deeper into the Weddell Sea are typically ice-classed.

The Antarctic PeninsulaAt this time of the year, it might still be possible to find fast ice to park the vessel in. EYOS has celebrated both Christmas Eves and New Years Eves on solid ice, having service directly from the vessel's gangway onto the ice. Aside from fast ice to park in and step on, ice navigation is a feature all along the coast. And if the vessel would like to transit South through the Lemaire Channel, famous for its high peaks and narrow channel (which is often blocked by ice), an ice-classed vessel is a significant advantage. South of Lemaire awaits fantastic skiing opportunities, ice navigation, wildlife sightings and landings.

The Ross Sea, Antarctica

13 Jan – 2 Feb / 6,065 NM / One charter / Fly in & out via Antarctica

Explorer yacht framed between blue icebergs

Ice navigation among grounded bergs, Ross Sea region.

The Ross Sea is located 1,500nm south of New Zealand and Australia and requires a yacht to traverse the entire Southern Ocean. This is the most exclusive Antarctic cruising destination and offers dramatic scenery, excellent wildlife and one of the most pristine places on Earth. Home to the original huts built by explorers Captain Robert Scott and Sir Ernest Shackleton, it is possible for guests to visit buildings that have remained in their original condition since the Heroic Era (1898–1920).

The Ross Sea is shielded by a vast band of pack ice that generally dissipates in mid January, offering vessels a few weeks of polar cruising before the first autumn storm arrives in early March. Vessels can expect to traverse a 10 to 30nm band of loose pack, and then enjoy relatively ice-free waters.

The Ross SeaThe Ross Sea is one of Antarctica's most remote regions, known for its extensive sea ice, vast tabular icebergs, and the Ross Ice Shelf. Depending on the season, vessels may encounter first-year and multi-year sea ice, as well as glacial ice. Ice conditions are often demanding and require careful planning using weather forecasts and satellite ice imagery. Access is generally limited to ice-strengthened or ice-classed vessels, with opportunities for wildlife encounters, historic site visits, and landings where conditions allow.

Greenland + the Northwest Passage

10 Aug – 10 Sep / 5,690 NM / Reykjavik to Nome

The Northwest Passage is an iconic voyage that spans across the top of Canada and Alaska to link the Atlantic and Pacific Oceans. Spanning 3,500nm from Nuuk, Greenland to Dutch Harbor, Alaska, the 'passage' consists of several different channels that are fully iced over in winter. The ice begins to dissipate in July and by late August most vessels are able to transit through during a 3 to 4 week window. Vessels with some ice capability are able to traverse the passage 2 to 3 weeks earlier. The Northwest Passage also includes areas that can be added to the transit, or cruised as a stand-alone itinerary. These include Ellesmere Island, Baffin Island and of course the west coast of Greenland.

Greenland offers a wide range of expedition opportunities throughout the year. In spring, Disko Bay is particularly well suited to ice-classed vessels, with sea ice often persisting well into the season. This provides access to exceptional heli-skiing terrain, while also allowing guests to experience ice navigation among icebergs and sea ice.

On the east coast, East Greenland is one of the most ice-affected regions in the Arctic. Sea ice and multi-year ice drifting south from the Arctic Ocean can remain well into the summer, making an ice-strengthened hull a significant advantage. The region offers dramatic fjords, extensive glacier systems, remote communities, and excellent opportunities for wildlife viewing and exploration in an area visited by relatively few vessels.

Greenland · glacial iceWhen approaching the Greenlandic south coast, it is not unusual to encounter heavier sea ice from the east coast being brought south by currents. Heading in to the fjords, the predominant type of ice is glacial ice. Greenland's west coast have highly active glaciers, producing ice bergs in a rapid speed. Ice navigation among intensively blue ice bergs and bits is a highlight here. In spring and early summer we may still encounter fast ice or large ice floes in the bays. The fast ice is fantastic platform to use for ice set ups, helicopter take offs or kayaking off the ice edge.

Self-Sufficiency

Endurance

A minimum of 40 days for regular itineraries in Northwest Passage, Ross Sea, extended Antarctic Peninsula periods. Ideally, a charter yacht operating in Antarctica would be able to do 60 days without shore support. Note that fresh provision can normally be flown in from the mainland on the charter flights used by guests.

Fuel

Enough fuel (min. 40 days, ideally 60). Sea water temperatures may be as low as −2 degrees Celsius.

Provisions

Food provision possibilities in polar regions are very limited and there can be weeks between possibilities. Ensure amount of provision is not limited by the holding capacity onboard.

Potable water

Water maker redundancy and sufficient holding capacity. Note that production capacity drops to 50% when the water temperature goes below 5 degrees Celsius. Water production is often interrupted due to silted water.

Waste

Consider holding capacity and waste handling systems such as compressor, glass crusher etc. We often see vessels with great fuel range but only garbage holding capacity for 1–2 weeks. Garbage can not be offloaded in Antarctic, and a full charter season could be 60 days.

Food waste

Polar regions have special food waste regulations. Ensure there is enough storage for food waste to be kept onboard for the duration of the trip. Consider food processing systems.

Sewage / grey water

Treatment plant for both BW and GW? Consider holding capacity as well. Certain areas (Norway) have a no discharge regulation, no matter if it is treated or not. There are ongoing discussions regarding a no grey water discharge in polar regions.

Stores for technical spares

'Bring it if you need it' applies to both the Arctic and Antarctica. To get hold of spares in these regions takes time, as all needs to be flown in. All spares considered critical for the expedition should be carried onboard. Consider stores in technical spaces.

Expedition Operations

Zodiac Mark V

EYOS recommends 2× Zodiac Mark V in addition to the yacht's tenders. These can be stacked. Preferably located far astern, so the vessel can give lee during Zodiac launch. The forward tech store will be difficult to launch and retrieve from in challenging conditions. Is there space in the tender garages?

Tender fuel capacity

Most common engine for Mark V is Yamaha petrol outboard engines. A Zodiac heavily in use requires about 25 liters/day. Petrol can be found in most Arctic communities but not in Antarctica.

Tender garage platforms

Consider clearance from waterline to the tender garage, so launching can be done even when weather is more challenging. The platforms will not be used when there is ice around, as there is a high risk that ice might damage them.

Transition area / mudroom

Guests returning from shore or tender cruising tend to be salty, wet and muddy. A designated area to take outer gear on and off is preferred (the 'Spa Lounge' could work):

Boot dryers; bench / chairs for wet gear
Clothing racks / hooks; shelves for gloves, beanies, walking sticks, cameras
Drink station, towels
Boot wash station ('Virkon' dip between landings, biosecurity)

Presentation facilities

A large screen in the guest lounge, with seats for all guests, for lectures, presentations or safety briefings.

Observation area

The outdoor area on top deck forward would be the best area for spotting wildlife, but will be very exposed. A glass wind shield would make it more comfortable in polar regions.

Heaters on outer decks

For guest comfort, heaters for dining and lounge areas.

Gangway gates

At various decks, to always be able to get guests on and off, even at locations with extreme tide or odd piers.

Supernumerary cabins

Noted two staff cabins (two bunks each?) on the GA. The EYOS polar team is normally 2 guides and 1 ice pilot. With skiing, ~3 additional ski guides. Helicopter team is 2–4 (one or two helicopters). Also consider local pilots (Norway), entertainers, nanny, security etc.

Helicopter

Two-helicopter capacity

Heli skiing in Antarctica is very popular and there are currently few yachts able to do it without a support vessel. The requirement is to carry two helicopters with two heli teams if the helicopter lands. Does the vessel have the beam for a sideways hangar? If a helicopter is parked there it would block access to the primary helicopter; a 2nd heli on the forward deck would obstruct the bridge view.

GA top deck, sideways hangar / cabin zone marked — Sideways hangar / staff-cabin zone (marked) — top deck

Helicopter Lounge

Suggesting a Helicopter Lounge on top deck, converting this area and making the hangar the centerpiece, with glass walls and the lounge around it. An area where guests get in and out of gear, get the final safety briefing, put lifejackets on. For heli skiing, where they can change ski boots to interior shoes.

Helicopter fuel tank

Located rather high. We often see it low due to stability, and it gets pumped up to the helideck.

Heli firefighting

For take off and landings, a firefighting team from the crew stands by close to the pad. There are no areas for the team to 'hide'; often sidewalks to the accommodation let them roll out hoses. No storage for firefighting equipment, so it would be brought up by crew through the guest accommodation.

Storage at heli deck

A deck storage close to the helicopter deck is convenient. For heli skiing, skis could be kept here between rounds, avoiding equipment being brought up and down during operations.

Owner's outer deck

Guests and crew heading to the heli or observation deck pass through the owner's private area. Shut off the staircase? With heavy helicopter use this could become a high-traffic area. Decks near the pad are cleared of loose items for take off / landing, so crew may access the owner's private deck for every operation. The jacuzzi water may also be at risk during approaches.

Fold-down sides

Cruise vessel 'Scenic Eclipse' has fold-down sides to protect the helicopter during sea transits.

Access to the Canadian Arctic is governed by the Shipping Safety Control Zones and a Zone / Date / Ship-type system. A vessel's construction standard, expressed as a Transport Canada Type (A–E) mapped from its ice class, determines which of the 16 zones it may enter, and during which dates.

Outside the listed period, a vessel may still navigate a zone only if the ice regime allows it: for vessels built before 2017, the AIRSS ice numeral must be zero or greater; otherwise the POLARIS risk index must indicate normal operation. Polar Class 3–7 vessels facing elevated risk must follow the mitigations in their Polar Waters Operations Manual. An emergency exception applies for saving life or preventing the loss of a ship.

Worked example

A yacht holding Ice Class 1C equals Transport Canada's Type D. A Type D vessel is allowed in Zone 16 between 1 July and 31 October. Outside that window, entry may still be permitted if the POLARIS risk index for that ice regime indicates normal operation. This is not guaranteed; it depends on the ice situation.

In short: the higher the ice class, the more zones the yacht can reach, and the longer the season it can operate. This is the regulatory floor underneath the design recommendations in Section 02.

The 16 Safety Control Zones

Canada divides its Arctic into sixteen numbered zones. Each zone opens to a given vessel only inside a set window, and the strongest ice classes reach the high zones (1–6); a light ice class is held to the outer, eastern zones in late summer.

Canada's sixteen Shipping Safety Control Zones on the Arctic globe — Figure 1 — Canada's sixteen Shipping Safety Control Zones, on the Arctic chart. Indicative zone extents; Schedule 1 governs the dates.

Ice Class to Transport Canada Type

A vessel's ice class is translated into a Transport Canada Type, A (strongest) through E. The Type is what Schedule 1 reads to decide zone access. EYOS recommends a minimum of Ice Class 1C for this newbuild, which is Type D.

Zone, Date and Type: Schedule 1

Schedule 1 is the master table: for each Type, the exact dates each of the sixteen zones is open. A Type D (Ice Class 1C) hull is shut out of the high Arctic zones entirely and reaches the eastern zones only in a short late-summer window, the constraint the worked example above describes.
