Vetus Unveils E-line Air Electric Propulsion Motors for Small Craft

Vetus, the Dutch pioneer in marine electrification best known for its thruster systems, has introduced a compact new line of electric propulsion motors called E-line Air. Announced at boot Düsseldorf, the series is designed specifically for repower projects and new builds on boats up to 26 feet, providing a space-efficient, quiet and low-maintenance alternative to small diesel or gasoline inboard engines.

Three Models Covering Typical Small-Boat Needs

The E-line Air family is offered in three sizes to suit different installation and power requirements:

• EAIR04024 — 4 kW at 34 volts
• EAIR040 — 4 kW at 48 volts
• EAIR060 — 6 kW at 48 volts

Each model is engineered to meet the typical power demands of tenders, daysailers and small coastal cruisers, while remaining compact enough for straightforward installation during repower projects or integration into new hulls up to 26 feet long.

Compact, Light and Direct-Drive Design

The E-line Air motors are intentionally lightweight and compact; the complete motor unit weighs approximately 143.3 lbs. All E-line Air drives use a 1:1 direct-drive configuration, which means the propeller rotates at the same speed as the motor. The absence of a gearbox simplifies installation, reduces moving parts and allows for smooth, instantaneous shifting between forward and reverse without the mechanical complexity of conventional gearboxes.

Battery Options and Monitoring Compatibility

Vetus supports several battery chemistries for its electric propulsion packages, offering Deep-Cycle, AGM deep-cycle and lithium battery options to match different budgets, weight targets and duty cycles. Choosing the appropriate battery type helps optimize runtime, recharge behavior and lifecycle cost depending on how the vessel will be used.

To support situational awareness and system integration, Vetus’ E-drive systems are compatible with NMEA2000 networks. When integrated with a vessel’s NMEA2000 system—or with Vetus’ own NMEA2000-capable components—users can monitor real-time battery state of charge, system voltages and other key parameters directly from compatible displays and multi-function instruments.

Benefits for Repower and New Builds

Electric propulsion offers several practical advantages for small-boat owners and shipyards considering repower or new construction:

• Quieter operation and reduced vibration, enhancing onboard comfort for day trips and overnight stays.
• Lower routine maintenance due to fewer moving parts and no oil or fuel systems to service.
• Instant torque and smooth throttle response, which can improve maneuverability in close quarters.
• Compatibility with modern monitoring systems like NMEA2000 for simple integration into existing electronics networks.

Installation Considerations

Because the E-line Air motors are direct-drive and relatively compact, they are suited to a variety of installation layouts commonly found in small craft. Shipyards and experienced installers should evaluate battery capacity, charging infrastructure and ventilation requirements for battery compartments during repower planning. Weight distribution and shaft alignment (where applicable) should also be addressed to preserve handling and seaworthiness after installation.
