Sauter Carbon Offset Design reduces fuel consumption by up to 50% in Superyachts at no extra cost
by making them less of a Drag.

Traditionally, above and below the waterline, it’s the Fluid Dynamic Inefficiency or the immense “Drag”of Superyachts that stands out as their weakest point. The most visible examples are seen in the conspicuous Radome towers and the bow waves of semi-displacement Superyachts which reach levels of Fluid Dynamic Inefficiency that are unmatched by any other form of passenger transport.



When it comes to Aerodynamic Drag, with the sole exception of boats, every type of modern surface transport, from trains to motor scooters have adopted innovations that dramatically reduce drag,thereby reducing their fuel consumption by up to 20%

In short Superyachts could reduce their outrageously large Carbon Footprint by employing well established Aerodynamic solutions that involve no risk, require no maintenance, have no movingparts and at virtual;at “no extra cost”.

One is tempted to ask why the Maritime Shipbuilding Industry has yet to adopt the fundamental Aerodynamic Principles seen in every form of modern transport which clearly reflects the knowledgeand ecological conscience of our age?

From a State of the Art Fluid Dynamic perspective it doesn’t seem possible to answer that question without putting other aspects of Superyacht design under scrutiny, namely the serious HydrodynamicInefficiency seen at work in the wave making signature of semi-displacement Yachts of every size and description.

If you are the owner of a semi-displacement Superyacht,you are probably not aware that this type of vessel consumes up to 30% more fuel than is necessary and doing so with Marine Diesels asopposed to EPA “ON Road” engines is emitting possibly up to 10 times more Toxic GHG Pollutants than it has to.

It’s time we saw fast fuel-efficient displacement Superyachts taking the place of their semi-displace- ment predecessors. The way to accelerate this process is by educating and thereby encouragingSuperyacht customers to demand that their vessels are all that the can be.

As with Aerodynamic improvements, the benefits derived from passive Hydrodynamic innovations are essentially a “no extra cost” way to reduce the staggering fuel consumption and GHG emissionsassociated with Superyachts not to mention the ever increasing numbers of Mega and Gigayachts. High levels of Fluid Dynamic Efficiency are achievable with hi-speed wave piercing displacement

Yachts that that function best cutting through the water. The enormous bow wave produced by semi- displacement Superyachts does make their presence known, but not without broadcasting a disregardfor the harmful effects of extreme Drag.

Towering appendages give Superyachts a higher profile, but not without defying common Aero- dynamic practices, common sense and the common good.
