REAL LIFE DATA:
Our OEM propulsion partners at Integrel Solutions have just published the third and final instalment of their E-Drive Performance Series — and it’s the most data-rich of the lot.
Parts 1 and 2 covered power generation efficiency and electric-only range respectively. Part 3 dives into intelligent hybrid motoring: what actually happens when one hull runs on diesel while the other runs on electric — and the results, drawn from real sea trials on a Balance 502, are compelling.
Key takeaways from the data:
- At 4.5 knots in hybrid mode, the system achieves a power generation efficiency nearly four times greater than a standalone diesel generator
- Just above 5 knots, the hybrid configuration matches twin-engine fuel consumption — but with only one engine running, cutting engine hours and maintenance in half
- Above 5.5 knots, the hybrid delivers genuine net fuel savings
For Balance owners running the VersaDrive, this is the technology working exactly as designed: propulsion and power generation operating as a single, intelligent system rather than two separate concerns.
