Next generation hull technology

Our patented technology enables boats to glide on a cushion of air which reduces energy usage by 50% compared to conventional hulls! This reduces CO2 emissions, enables battery or other zero-carbon propulsion solutions and significantly reduces costs.

Surface Effect Ships (SES) is a term for vessels that are lifted out of the water by pressurized air, and is a well-proven technology often being used in high-performance military applications

Our unique SES solution is a mix of catamaran and monohull – gaining the upside from each technology - with soft motion and increased comfort and seakeeping capabilities from the air cushion, increased stability from the catamaran and low hull complexity from the monohull. Additional benefits are significantly reduced waves – highly beneficial in sheltered waters.

Three types of planing hulls - conventional hulls are inefficient

There are three key types of planing hulls: conventional, surface effect ships (SES) and hydrofoils. It is an established fact in maritime tech that SES and hydrofoils have 50%+ energy savings compared to conventional hulls. Yet, conventional hulls have 95%+ of the market. Given the urgent need to go carbon-neutral on water, SES and hydrofoils must take large market shares from conventional as soon as possible.

The key problems with hydrofoils are safety, reliability, high complexity and radical redesign of the boat itself and its geometry and depth in water.

We take SES to the mass markets

 A big problem with traditional SES is the costly high maintenance rubber skirt and air bag that is used to contain the air. Our patented solution is simply air cushion cavity integrated into the hull – eliminating the use for skirt and bag. Simple and elegant - high performance without compromise - this is how SES will be brought to the mass markets.

Yes – 50% energy savings! 

It is an established fact in the maritime domain that SES is highly energy efficient, and our full scale prototypes show plus 50% reduced fuel consumption compared to conventional hulls – testing by Motor Boat & Yachting November 2010.

SES-X hull technology combined with high efficiency electric propulsion systems, can take the total energy usage down one order of magnitude compared to conventional diesel vessels.

In the figure below, the two blue lines represent boats with SES-X's Air Supported Vessel (ASV) technology. The two grey lines represent conventional boats at similar length and weight.

Significant wave reduction

Wake wash reduction - enabling faster travel in coastal regions and congested waters - a highly sought-after feature for fast commuter ferries and fast work boats.

Full scale concept verification through two pilot vessels

BB Green: The world’s first 20 m and 30 knots fast battery powered commuter ferry with Volvo Penta IPS propulsion. Design Studio Sculli, construction at Latitude Yachts, Latvia.

Tuco workboat: 2015, Tuco Soft Motion Demonstrator, 18m crew transfer ferry,  powered by 2 diesel-driven Volvo Penta 600 pod drives / IPS - operating at 37 knots. At a speed of 25 knots, the total system (propulsion and air lift fan) fuel consumption is only 3,0 liters per nautical mile. This boat is built by Tuco Marine Group in Denmark.

Technology is a result of decades and 20MUSD in R&D

2500 towing tank model tests at SSPA in Sweden have contributed to the development, test and verification of the hull technology and design principles for a series of ship concepts. This has resulted in an optimized hull design capable of tackling various sea states - which is the key to commercializing the technology.
