The concept of multiple inputs for tugboat power continues to evolve

Anytime there’s a legit, suitably notable “first-in-the- world” introduction, it’s usually a big deal. Such it was on a rainy day in 2009 when Foss Maritime unveiled the world’s first hybrid tug, the Carolyn Dorothy. Maybe 300 guests heard speakers from Foss and the ports of Los Angeles and Long Beach tout the new environmental credibility of the tug, which was the point of the ports’ $1.3 million grant money that helped build it.
