Rhodan Marine Systems

What Rhodan Marine Systems does

Rhodan Marine Systems (legal entity: Rhodan Marine Systems of Florida, LLC) is a Sarasota, Florida-based specialty marine electronics manufacturer founded in 2016, operating with 11-50 employees. The company designs, manufactures, and sells GPS-guided trolling motors, with the GEN 5 as its flagship fifth-generation product. Its core technology is the HD GPS Anchor+ system, a differential-GPS receiver that holds a boat's bow on station by automatically compensating for wind, waves, and cross-current, supplemented by manual, track, and route-playback operating modes, wireless remote and app-based control, and a full screen base display reporting voltage, current draw, speed, and heading. Rhodan manufactures the majority of its products in-house at its Sarasota facility, claiming 90% U.S. content in the Gen 5 motors.

The product portfolio spans the Gen 5 motor platform (24V, 36V, 48V configurations; 48-120 inch shafts) and the ABYSS sub-brand of lithium marine batteries (12V, 24V, 36V) and a full charger family (on-board precision chargers, alternator chargers, bi-directional DC-DC chargers, and NOCO distributed units), plus replacement parts and accessories (lower units, quick-release brackets, prop kits, covers, FOB remotes). The Gen 5 motor carries built-in integration with Simrad, Raymarine, and Lowrance marine electronics, UL/IEC/CE/UN38.3/ROHS battery certifications, and a 5-year limited warranty.

Rhodan runs a hybrid B2B/B2C go-to-market: direct e-commerce through rhodanmarine.com paired with a regional marine dealer locator network for installation and in-person purchase, plus social (Instagram) and email newsletter demand generation. Revenue mechanics are unit-based hardware sales at premium price points (motors from $3,779.99; ABYSS 36V 60Ah battery at $1,999.99; accessories $11.99-$499.99), with no disclosed subscription, software, or service revenue. The customer base is fragmented recreational and offshore fishing enthusiasts with no named enterprise accounts, implying low customer concentration. Ownership is described as locally held with no institutional or private equity backing disclosed.

• MotorGuide: Brunswick-owned trolling motor brand offering GPS-enabled and pin-guided motors. Competes head-to-head with Rhodan in the same retail and OEM channels.

Broad incumbents

• Garmin: Major marine electronics incumbent that owns the Force trolling motor line and through Navico also owns Lowrance. Competes with Rhodan's motor business and controls a key integration partner.
• Lowrance: Marine electronics brand under Navico (Garmin). Functions as both an integration partner for Rhodan GEN 5 and a potential competitor via the broader Garmin trolling-motor portfolio.
• Raymarine: Premium marine electronics brand (FLIR/Teledyne). Functions as an integration partner for Rhodan GEN 5 and an adjacent incumbent in the marine electronics ecosystem.
• Simrad: Marine electronics brand under Navico (Garmin). Functions as a core integration partner for Rhodan GEN 5 and a broad incumbent in marine navigation and control systems.
• Brunswick Corporation: Marine conglomerate that owns MotorGuide, Mercury Marine, and numerous boat brands. Comparable as a deep-pocketed incumbent shaping marine propulsion competitive dynamics.

Emerging players

• Torqeedo: Electric marine propulsion specialist (outboards and pod drives). Comparable to Rhodan in electric marine DNA and lithium battery integration, but focused on higher-power applications.
• ePropulsion: Chinese-born electric outboard and marine propulsion company with growing U.S. presence. Comparable as a competitor targeting electric trolling and small outboard segments with lithium-battery integration.
