I fiddled with the “Waves” properties sheet and entered some 9 meters high waves with 500 foot lengths (to be shorter than my model’s LPP. The resistance calcs didn’t seem to change.

That’s correct. The resistance calculations are based on statistical tank data with still water. The results from the resistance calculations obtained by using a wave in the hydrostatics would be completely out of the valid range of the test data and therefore unreal. Not to mention the fact that the Delft series and Kaper are not really suitable for 500ft ships B)
