Problem we are solving
13 Mari has developed an innovative way to reduce cargo ships' drag, thereby lowering fuel consumption to reduce carbon emissions and align with the maritime industry's goals.

The addressable market is estimated at $6.7B p.a., with 1/5 of it as a 13 Mari take rate (the product comes with 1 ROI in a 5-year scheduled maintenance-voyages-scheduled maintenance cycle). The CO2 elimination potential of the technology is estimated at 45,000,000 tonnes p.a..

The product is back by recent advancements in understanding origins of the fluid drag in a turbulent flow regime. It is decoupled from a propulsor and applicable to all vessel hull types, regardless of fuel and engine type, making it of interest longer term.

The 13 Mari product won the Captains Table global Maritime competition in Hong Kong, also won by Greywing and Clearbot. https://youtu.be/QJR6p98Kst4

Sustainable Impact on Blue Ecconomy
Passive, simple, zero OPEX product reducing fuel consumption and associated with the fuel wel- to-wake emissions by up to 7% across the entire commercial fleet. While there is no direct competition to the 13 Mari product, none of the competing energy saving devices come close in terms of return of investment and overall efficiency.

The product comes with 1 year return of investment. Just as an illustration, the following median fuel cost savings p.a. are projected across the different commercial vessel types:

Handysize $120,000
Handymax $150,000
Supramax $160,000
Panamax $180,000
Post-Panamax $200,000
