I know it's possibly vapour but I wish they build the craft and find a market for it to make it commercially viable. I was thinking Hawaii, Canary Islands, Azores, Balearic Islands, crossing between Sardinia and Corsica and from around Messina Sicily to mainland Italy, Japan, South Korea (eg. Wando-Jeju), NZ (eg. Wellington area to Waikawa or Picton). You don't need shipping port or ferry infrastructure for it, a smaller port or a marina with good acces to electricity might be enough. For the rest of SE Asia it might be too expensive, but it might be useful in the Philippines and Indonesia.
