Electrify Any Boat. Anywhere.
Custom-configured. Expert-selected. Delivered.
Battery-hybrid packages for power & sailboats between 25-100ft. From concept to open water, we electrify boats for builders, yards, and owners ready to make the switch.
Our packages include: design drawings, machinery and equipment, generators, batteries and power electronics. Everything is packaged in a container to be shipped to your nearest boat yard for installation.
Smaller & Lighter
Smaller footprint, fewer components, and no need for soundproofing. Our systems are compact and intelligently integrated. On Karma, we actually opened up significant service space — making residual systems easier to access and maintain. It’s a cleaner, more streamlined setup that makes the most of your mechanical room.
Power
OSEA systems are designed to meet all your propulsion and hotel load needs—so you can cruise, cook, charge, and unwind without limitations. Everything you need, powered effortlessly.
Performance
OSEA delivers the comfort and convenience of life on land—at sea. No more power juggling, no more range anxiety. Just reliable, responsive energy that lets you enjoy your surroundings without compromise.
Charging
OSEA is charged by whatever power is available — generator, shore or renewables. We design the system to take advantage of your existing infrastructure.

Quiet Strength
Maximum Range
Quiet instant power
With quiet, instant response and precise control, you’ll notice a big boost in maneuverability and onboard safety.
Cruise longer, refuel less
With 1,700 nautical miles on 400 gallons, Karma shows what it means to go farther—cruise longer, refuel less.
Anchor for days in silence
With 3–4x the battery capacity of a typical vessel, stay at anchor without the hum of a generator. Extra capacity and renewables mean longer, quieter nights on the water.
