I am not sure regular hydrofoil cargo ships are practical. My understanding is that hydrofoils don't do well in high seas. All the passenger ferries I know about are in coastal waters. It may not be possible to have one that can cross ocean and deal with storms. The Boundary Layer proposal is pretty small, 200 tons and 20 TEU capacity. It would have the same scaling problems as the sailboat in article. Is there a market for slightly faster shipping? The hydrofoil is 40 knots which is 6 days from China, container ships are 20 knots and 11 days. If there was a market for faster shipping, would expect to see 30 knot ships. I bet the really urgent needs air and current cargo aircraft are sufficient.
