Still, why is this not the future of sailing?
The kick-in point is programmable.
I think it is the future but it's going to take several years for the systems to evolve. They need to operate off of high voltage for efficiency just like the Prius. But meanwhile we don't have standards and experience for using high voltage in boats. Hybrid systems are more complicated than direct drive diesels and need more specialized engineering per vessel. There are more barriers than with the current diesel drive solution.
The catamaran is ideal for this since you can replace two diesels with one relatively smaller one thereby freeing up space in the aft of the hulls.
If I had a vessel with a blown engine I'd probably repower with a custom hybrid system.
