You know, it's a fair point that the diesel-electric part is actually a significant improvement in efficiency, at least according to the article. There's a reason trains don't use mechanical transmissions anymore.

But yup, she's hauling around a lot of deadweight for no practical reason.

You are exactly correct and carrying the extra weight makes it less efficient. And, if the batteries were fully charged, how many trips could the ferry make with the diesel turned off? More like old diesel submarine technology now that I think about it. I’m surprised that they didn’t put solar panels on it. But it’s Seattle and maybe some outside advisor showed them how much sunshine to expect.
