I had no idea that would be the cost of a ferry albeit old. We have a massive problem with transportation between islands due to lack of ships/investment. For example, out of the 9 islands only three have daily voyages and right now even that isn't happening as one boat broke down and another is away on maintenance. We could do we a couple even old ones.
The main issue I saw here with the electric ferry was that 90% of the installed generation in the islands uses HFO so we would be charging the ferry with a fuel that pollutes more than the diesel used to run it.
General survey of ferry prices in the 25+ meter range to give you an idea. Length number can be changed to filter for longer / shorter. There's 37 in the 25+ range, 19 in the 50+ range, and 11 in the 100+ range currently, although a few false positives on the keyword matches.
