Discover how 13 Mari can advance your maritime operations with cutting-edge fuel cost reduction and fleet optimization strategies.
Reduce drag, cut emissions, and save fuel with our award-winning hull technology.
Advancing green shipping with nature-inspired solutions that make vessels cleaner, faster, and more efficient
Cut fuel costs, optimize operations, and enhance sustainability with our innovative maritime technology.



















Fuel costs are soaring. Regulations are tightening. The pressure to decarbonize is increasing. Ship operators need reliable drag reduction solutions that cut CO₂ emissions without adding complexity.
At 13 Mari, we deliver low-cost, patented, passive hydrodynamic technology that boosts fuel efficiency for commercial vessels. Our engineered hull elements reduce water flow resistance, lowering operating expenses. The solution is always on, applicable to any hull form, engine and fuel type, and at zero operating expense.
Using advanced simulations, precision hull mapping, and towing tank validation, we tailor each solution to the ship’s unique flow dynamics for fleet optimization. Our composite elements require no power, maintenance, or structural modifications, making them a simple, scalable upgrade for any fleet.
