Increasing Fuel Efficiency through Propeller Upgrades

Hello,

I am looking into ways to increase the fuel efficiency in a various number and type of ships, with engines running from diesels to steam plants to gas turbines. I was wondering where I might find information on the state of the art practices with propeller design.

Specifically, what is better for constant low speeds, high speeds, fast acceleration, etc.

I've read about contra-rotating thrusters, highly skewed propellers, BTL, TVF, and many others. What parameters are best to look for to assess the practicality of energy savings with different propeller designs?
