Aerodynamics can be quite complex. Don't forget that water is over 800 times as dense as normal air pressure. Also Reynolds number is very important. Look it up if you don't know how it affects lift and drag.
Also sometimes attached flow can create more drag than a shearing action. See Kammback for examples. Many principles are fairly universal but there's the details that makes it all work for a given scale and form factor.
