A parallel hybrid system
Introducing EcoDrive. A Parallel Hybrid System
EcoDrive is a robust and redundant hybrid electric/diesel propulsion system designed to deliver a multitude of benefits. Originally conceived in conjunction with the HH44, the Parallel Hybrid EcoDrive is a ground breaking industry advancement that we’re proud to now offer on all HH Catamaran models.

A traditional Diesel engine is coupled with a large electric motor. Much like an alternator sits on a diesel engine today, a belt connects the two units and a simple cam shaft allows the user to switch between the two, creating the ultimate redundant propulsion system.

This depends on the size of the unit and the size of the boat (we offer this across our range), but on average the systems are designed to conservatively offer 1.5-3 hours of silent, fume free, electric propulsion without requiring the owner to carry an unnecessarily large battery bank. This should be more than enough time to exit the marina or anchorage, hoist sails and regenerate power as you sail away. With 4.2kW of solar, the lithium batteries should charge quickly and massively extend the range.

Working with other brands, the Hudson Yacht Group has built several serial electric/diesel hybrid boats, and the technology used has been historically problematic.
We feel the battery technology today is not ready for an electric-only boat. We took the learnings from these previous projects and are working to develop a system that is ready now, and that can be trusted to provide a reliable, trouble free, eco-friendly option to our clients.
