Navgathi Marine

What Navgathi Marine does

Navgathi Marine, doing business as Navalt, is a Kerala, India-based designer, engineer, and manufacturer of solar-electric and battery-electric marine vessels founded in 2008. The company operates a broad product portfolio spanning ferries (Aditya, Aditya Supernova, Poseidon, Vega, Riveire), cruise boats (Limo, Marsel, Avalon, Avalon Plus, Maritimus), water taxis (Nirva), fishing boats, defence and security vessels (Third Eye, Indra, Dialga), and RoRo vessels. It also sells two technology platforms: Oceanix (vessel performance analytics) and Greenship (electric propulsion and energy systems for large vessels, including retrofit/greenification services).

The core technology is an integrated electric propulsion architecture centred on the in-house STING LTO Battery Pack — a Lithium Titanate battery system certified by Class NK (Nippon Kaiji Kyokai), reported as the first such approval in India for marine applications. Navalt controls the stack from battery cells through electric drivetrains, vessel hull design, and an analytics layer, positioning itself as a vertically integrated marine EV OEM rather than a system integrator. Notable deployments include the Aditya solar ferry (India's first), a 100-tonne capacity vessel under construction for a State Water Transport Department, and the LIMO luxury cruise boat delivered to Mr. Joy Alukkas for Isle of Joy operations.

The business model is B2B hardware sales of custom and standardised vessels, supplemented by retrofit services (Greenship) and a nascent subscription analytics offering (Oceanix). Pricing is quote-based with no public disclosure. Go-to-market relies on direct enterprise sales to government water transport departments, commercial ferry and cruise operators, and defence organisations, combined with a 'Become a dealer' channel programme for regional distribution. Navalt reports active deployments across 11 Indian states and five countries (India, Israel, Canada, Maldives, Seychelles). The legal entity is Navalt Solar & Electric Boats Pvt. Ltd (with a related entity, Navalt Green Mobility Pvt. Ltd), both privately held in Kerala. Headcount is reported at 22 employees, no funding rounds or institutional investors are disclosed, and revenue is not publicly reported.

Direct peers

• Torqeedo: German manufacturer of electric marine propulsion systems and integrated battery drives. Direct competitor to Navalt's in-house electric propulsion and STING LTO battery pack on the technology axis, especially for small-to-mid-sized commercial and leisure vessels.
• Vision Marine Technologies: Canadian electric boat powertrain and boat company selling fully electric recreational vessels. Directly comparable to Navalt on full-stack electric boat delivery, with a similar small-cap, publicly listed profile and multi-market presence.
• X Shore: Swedish premium electric boatmaker for leisure and commercial operators. Comparable to Navalt on the combination of integrated electric propulsion, design-led vessels, and a focus on silent, zero-emission water transport as the core value proposition.

Emerging players

• Corvus Energy: Canadian-Norwegian supplier of lithium-ion battery energy storage systems for marine and hybrid propulsion. Directly comparable to Navalt's STING LTO pack on maritime-certified battery systems, and a likely competitor or partner depending on tender specifications.
• Zin Boats: US electric boat builder focused on recreational and commercial electric vessels with integrated propulsion. Comparable to Navalt on full electric vessel delivery for premium and small commercial use cases.
• Arc Boats: US electric recreational boat company integrating in-house battery and powertrain. Comparable on the vertically integrated approach of combining boat design with proprietary battery/electric drivetrain technology.
• Evoy: Norwegian electric outboard and inboard propulsion systems for commercial and leisure boats. Overlaps with Navalt on electric drivetrain and battery systems for commercial-scale vessels (ferries, workboats, tourism).
• Echandia: Swedish provider of marine energy storage systems based on LTO and lithium-ion chemistries. Directly comparable to Navalt's STING LTO pack on maritime-grade battery systems optimised for high-power, long-cycle applications.

Broad incumbents

• Wärtsilä Marine: Global marine technology major offering hybrid and electric propulsion, energy storage, and vessel services. Overlaps with Navalt's Greenship large-vessel electrification offering and STING LTO battery systems, but at much larger scale and across broader vessel classes.
• ABB Marine & Ports: Major supplier of marine electric propulsion, drives, batteries, and shore power systems. Comparable on the electric/hybrid propulsion and energy storage axis that Navalt addresses for ferries, RoRo, and large vessels.
