Sea Hawk
—103 m

Sea Hawk is a true expedition yacht, designed for those with a sense of adventure. Robust, capable and luxurious, it can travel to the most challenging environments in total luxury.

Breaking the ice

With a Polar Class 6 rating, Sea Hawk has a strengthened hull that can break through 80 cm of medium first year ice with old ice inclusions, giving exceptional access to the unspoilt and majestic scenery of the Polar Regions.

Ice Friendly hull shape
The hull is designed for safe navigation in polar waters, pushing through smaller pieces of ice or breaking through thicker ice.
Expedition style Sea Chests
In the Polar Regions there is a chance of ice and slush entering sea chests and inlets, which can block seawater flow to the ship's systems. To avoid this, compressed air and steam may be introduced to clear the ice and slush.
Highly manoeuvrable
Our yachts are designed with Becker rudders and strong side thrusters for efficient operation and manoeuvrability. Extendable azimuthing propellers also provide extra manoeuvrability and dynamic positioning.
High-power boiler for cold environments
To operate comfortably in cold climates our yachts are designed with high-power boilers and heating systems.
Reinforced Ice Belt
The hull has thicker plates and narrower frame spacing at the bow and around the waterline, which protects the hull from ice interaction.
Heated shell door seals
Heated seals avoid the chance of door seals freezing in cold climates.
Oversized propellers and machinery
All yacht machinery has been developed to meet the requirements of ice interaction and polar expeditions.
Designed for ice accretion
Sea Hawk is designed to be stable with up to 100 tons of ice accretion.

Sail beyond the sea

Not only is Sea Hawk able to withstand polar climates, it is equally capable in tropical climates, with the ability to travel through warm waters and up silty rivers, opening up the wonders of this unique but challenging environment.

Effective cooling capacity
Water temperatures in the Amazon can reach up to 36°C, putting a strain on ship systems. The oversized cooling capacity system keeps engines from overheating whilst travelling in hot waters.
Insect Filters and Pollen Barriers
At sunset in tropical regions, there tends to be large amounts of insects in the air. Easily accessible filters will be installed so that insect blockages in air conditioning filters can be cleaned away.
Maintenance friendly water intakes
River water is often silty, increasing the likelihood of blockages in the engine cooling systems. Our systems are easily accessed for cleaning in such conditions.
Oversized air conditioning systems
Air-conditioning will be installed that is capable of dealing with extremely high temperatures, humidity and condensate.
Freshwater production
Easily accessible filter systems and brackish-water permeators for reverse osmosis freshwater production will be installed.
Oversized propellers and machinery
Sea Hawk's machinery and systems are engineered to withstand interaction with floating logs and debris.

Luxury without limits

The yacht experience is just as much about the journey as it is the destination. With an 18m wide beam and six decks, there are extensive possibilities for luxury features.

Accommodating guests
We have a set of flexible designs in place for accommodation, including everything from large staterooms for up to 12 guests to spacious accommodation for up to 36 guests. Concepts also include extensive entertainment spaces which are ideal when hosting events for business or pleasure.
Helicopter Hangar and Bar
The helicopter hangar and bar is a unique design that showcases the helicopter alongside the bar area, so that instead of the hangar being hidden away, it can be used as an entertainment area for guests, and also provides some of the most stunning views on the ship.
Wide interior spaces
Sea Hawk’s spacious interiors are ideal for implementing design concepts, including a 330m2 mezzanine spa over two decks, with a gym, sauna and massage parlour.

Explore further

Sea Hawk is a true expedition yacht. With maintenance friendly systems and an impressive range, it is designed for long haul expeditions and extensive exploration.

Self sufficiency
Sea Hawk is designed to operate away from ports and infrastructure and maintain safe operation in remote locations, with redundant systems built-in where possible.
Generous storage facilities
Providing plenty of storage, Sea Hawk can be taken to sea for over three months.
Get Home Mode
With the ability to provide propulsive power from any one of the six engines and a retracting azimuthing thruster, which can be used as backup propulsion, the ship can operate in a ‘get home’ mode to allow the yacht to continue its voyage out of remote areas without assistance.
Expedition Side gates
The expedition gates provide separate areas to prepare for expeditions, and ensure that guests can disembark for landing and moving on to the supporting tenders safely. The tenders are designed to cope with extreme conditions and have interior seating for travelling further afield in cold or humid climates.
Long haul range
Sea Hawk has a 12,000 nm range at 12 knots (Electric Mode).

Ecologically protected areas

Some of the most beautiful locations on earth are protected by strict ecological restrictions. We have designed yachts that meet the stringent requirements of travelling through ecologically protected areas, so that these extraordinary and remote locations can be explored.

Electric mode
Using the hybrid diesel-electric propulsion system, which is adapted to future emissions regulations, the low-impact Electric Mode uses the generators alone to sail quietly and without vibrations at speeds of up to 12 knots.
Ocean waste regulation
On board incinerators for burning waste and sludge, biological sewage treatment, metal shredders for storage, cooled waste storage and sophisticated grey water treatment facilities minimise the effect of ocean waste.
Fuel tanks
We have avoided fuel tanks being in contact with the shell anywhere forward of amidships to avoid the chance of fuel spillage.
Yacht expedition is not about going rough, it's about access to the memorable exclusivity of unspoilt nature in comfort, safety and style.

Special features

Keeping systems in check

Keeping systems in check

Incorporating state of the art technology, Sea Hawk offers extensive remote monitoring of the engines and machinery. It detects required maintenance up to 6 months in advance and alerts to critical cases 7–30 days in advance. As a result, problems and operational trends are spotted before failures occur, resulting in proactive maintenance, optimum times between overhauls, less downtime and reduced costs.

Beautiful design in practice

Beautiful design in practice

The innovative Hawk Bow shape seamlessly combines beauty and functionality. It encloses the forecastle at the front of the ship, protecting systems that can get damaged or worn in heavy seas. Effectively 1.5 decks higher than a traditional bow, the shape is designed to break and throw aside large waves instead of scooping them up. This makes for more comfortable and efficient sailing through heavy seas.

The hull is designed for smooth and economic sailing in a wide range of conditions. It has large bilge keels and retractable fin stabilisers for efficient and steady sailing, and an ice friendly shape, so it can push through up to 80 cm of ice.

A new perspective

A new perspective

The asymmetric bridge was designed so that guests could be part of the expedition experience. With their own dedicated viewing space beside the captain's, they can gain an insight into how the ship's navigation and radar systems work.

Power management

Power management

Sea Hawk is powered by a highly efficient and clean hybrid diesel-electric power system, adapted to future emission regulations. The four generators and two main engines can be used together or separately to power the ship in three modes.

17.2 knots


The main engines power the yacht at speeds of up to 17.2 knots.

12 knots


The generators power an electric motor for slow speed cruising and sailing without vibrations at speeds of up to 12 knots.

18.2 knots


Using both the main engines and generators to power the ship it can reach speeds of up to 18.2 knots.
