Hybrid Electric
Packages

A lot less than you’re used to.

The electric components require minimal upkeep — around 10% of what a traditional diesel setup demands. And when it comes to our generators, you’ll see up to 40% savings on maintenance thanks to fewer running hours and steady-speed operation. Less time at the boat yard. More time on the water.

Quite the opposite.

Our systems are compact and intelligently integrated. On Karma, for example, 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.

Typically, between 3 days and a full week — completely silent, fully powered.

We size your battery system based on how you use your boat, so you can enjoy quiet anchorages without compromise. Run your lights, galley, systems — everything you need to stay comfortable and connected, without ever starting a generator.

That depends on your system setup — but in most cases, you’ll go farther with less fuel.

Take Karma, for example: with its original diesel setup, the range was around 1,800 nautical miles. As a serial hybrid, it now reaches over 4,500 nautical miles. That’s more distance, fewer fuel stops, and a dramatically reduced environmental footprint.

Absolutely. OSEA systems are designed to charge from whatever’s available — shore power, generator, or renewables.

We tailor your setup to match your existing infrastructure, so you can plug in at the dock, top up underway, or harness solar at anchor. We’ll size your shore power input based on your boat’s needs — whether that’s 30A or 100A, single-phase or three-phase. It’s seamless, flexible charging — built around you.

Absolutely — and our track record proves it.

The team behind OSEA has spent the last15+ years designing and installing some of the world’s safest marine battery systems — on vessels that operate 24/7 in some of the toughest conditions on earth. From offshore supply ships to ferries, our technology has been trusted where safety is non-negotiable. That same expertise goes into every OSEA system.

It’s extremely unlikely — and even then, you’re covered.

OSEA hybrid systems are built with redundancy. If your battery ever runs low, your generator automatically takes over to keep you moving. And just like any diesel-powered boat, you still need to manage your fuel — only now, you have more flexibility and more ways to stay powered. You’re never left without options.

Service is not included in our design quotes, be we do offer inclusive service packages to all of our customers at the time of purchase. Our Service packages include all maintenance costs and parts needed, but do not include travel expenses or shipping if different from the home port.
