We help shipowners future-proof their fleets with innovative tech that aligns with tightening maritime regulations and their sustainability goals.
13 Mari offers a passive drag reduction system that improves ship fuel efficiency and low-carbon shipping without altering how vessels operate. Our patented composite elements are designed to reshape the flow of water along a ship’s hull. This helps reduce resistance and increase hydrodynamic performance.
We start with a detailed analysis of the vessel’s hull using advanced computational fluid dynamics (CFD) simulations and towing tank testing. Our proprietary mapping software then determines the optimal location for each element based on flow behavior and hull geometry. These lightweight components are installed using marine-grade epoxy, requiring no welding or structural modifications. Installation can be done in a single day during a regular dry dock cycle or underwater, with zero off-hire time.
Fuel savings typically begin immediately, helping offset rising energy prices and tightening budgets.
With rapid installation and nodowntime, fleets remain operational and profitable.
Our elements are built to last at least five years and support long-term fleet optimization goals.
The passive design means no power input, no moving parts, and no new onboard equipment.
The system supports decarbonization efforts and helps vessels stay aligned with IMO emission targets.
Commercial shipping is under increasing pressure to operate more efficiently and sustainably. Rising fuel costs continue to erode profit margins. Tightening environmental regulations demand low-carbon shipping. Shipowners and operators must also contend with high retrofit costs, off-hire time, and complex systems that often require ongoing maintenance or onboard integration. In this landscape, fleet optimization and energy efficiency are no longer optional; they're essential for long-term competitiveness.
Many solutions on the market add complexity or require operational changes that slow adoption. What the industry needs is a simple, scalable, and proven method to improve performance without disrupting day-to-day operations or ship design.
