How Hybrid Propulsion Actually Works
Diesel acts as a generator only — never drives the prop. Electric motor drives the shaft at all times. Silent operation. Efficient at low speeds. Best for defined coastal routes with available charging infrastructure.
Diesel and electric motor both connect to the shaft — switchable or simultaneous. Silent electric mode at anchor and low speed. Full diesel power offshore. Three modes: electric only, diesel only, or both. Redundancy built in.
No diesel propulsion at all. Battery to inverter to motor to shaft. Zero emissions underway. Range is the primary constraint — best for defined short-range use cases with reliable charging infrastructure.

Frequently Asked Questions
A hybrid yacht combines a diesel engine and an electric motor — in a parallel hybrid system like Greenline's, both connect to the prop shaft and are switchable or simultaneous. You can run in silent electric mode at anchor or low speed, full diesel offshore, or both for maximum power. It is a fundamentally different experience from conventional diesel — not just a different engine.
Real-world fuel reductions of 20–30% are typical for coastal cruisers using a parallel hybrid system at displacement speeds. At anchor, solar panels and batteries run house loads without a generator running. The savings are most pronounced for owners who spend significant time at low speeds or on the hook — Great Loop cruisers, liveaboards, and ICW travelers see the biggest benefit.
Yes — and it is increasingly viable for vessels 40 feet and larger. The process involves integrating an electric motor alongside existing diesel engines, adding a lithium battery bank, and connecting a solar array and charging system. YSI works with leading propulsion engineers to assess suitability, specify components, and manage the project from initial survey through commissioning and sea trial. A good hybrid system is engineered as a whole, not assembled from parts.
As an authorized U.S. Greenline dealer since 2017, YSI offers the full current lineup: Greenline 39, 40, 42, 45 (Fly and Coupe), 48 (Fly and Coupe), and 58 (Fly and Coupe). All models are available in diesel, hybrid, or full electric configurations. New inventory, pre-owned brokerage units, and demo sea trials are available from our Fort Lauderdale headquarters.
Hybrid yachts have demonstrated strong resale demand — particularly as fuel costs rise and more marinas introduce low-emission zones. The buyer pool is more specific than conventional diesel, but those buyers ask better questions and understand what they are buying. Documentation matters: boats with clearly explained systems and realistic maintenance records sell well. Greenline yachts in particular have maintained strong pre-owned demand.
