There was research done into compliant "shark skin" ("dolphin skin"?)
coatings for subs that greatly decrease drag - and recently a shield of air
around the sub to completely eliminate drag, although at the cost of not
having any control over trajectory. We need more research into these ideas
- a sub traveling at, say, 50 m below the surface would surely avoid all
(most?) weather related effects, and have as smooth a ride as maglev
(barring tidal waves).

How high do waves get, anyway?
