Several of the diesel ferries that operate from Auckland harbour will be replaced with electric ferries next year and in 2026. Apparently ferries in Auckland carry only 6% of public transport passengers, but account for 20% of the public transport emissions [0].

Going fast in water takes incredible amounts of power.
I don't know why hydrofoils aren't more popular
Because they're expensive and unreliable for most applications. They need more power, they increase draft, they don't tolerate debris, and they really dislike rough seas.
