It would definitely use more energy, and container shipping is all about efficiency. It's a non-starter.

- petschge 7y agoare you sure? wave drag is a big part of the total drag ob a ship. which is also why dolphins go pretty fast with much less than one horse power.
- usrusr 7y agoMany military subs are actually faster submerged than surfaced. The wave drag (or wave resistance, to disambiguate from the shock wave drag of supersonic aerodynamics) referenced in sibling comment is the energy contained in the waves created by a surface vessel. The details that you'd have to understand to optimize a hill shape are quite complicated, but for a simple surface vs sub comparison it's enough to know that surface waves exist and that they contain energy that is projected away. A sufficiently submerged vessel does not create those.
