Fairly large hydrofoil ships have been built before so it will probably work from an engineering standpoint. But the economics are questionable. They're betting on finding customers who want a middle option between slow, cheap container ships and fast, expensive air freight. I'm skeptical that many such customers exist.

Hydrofoils obviously can't operate safely in heavy sea states. When a storm comes up they'll have to delay sailing, or route around. That will add some unpredictability to delivery schedules.
