Adding/Replying to my post:

I just realized that an item of difficulty might be in basic assumptions of propeller design and efficiency. I don’t know whether or how DELFTship assumes anything about propellers when it does the resistance calcs. Maybe these are simulations of a towed model having no propeller appendage? Since each prop is hull design specific, maybe a module to allow for ranges of efficiency would be useful, such as 75% through 90% for traditional props, and some other, reasonable values for ducted/tunnel/azipod types of propulsion.
