Their freeboard isn't far from some similar coast defense or escort cruiser designs. Here's some of the designs operating now. I've made no attempt to take account of their sizes, but some of the higher-freeboard ships, like Calabria, Elba, Alswinn, Ringhorn, Tyrfing, Gugnir, and Nagelring have a top speed of 24-25 knots, which is significantly higher than either Revansh (1
or Varyag (20). So if there's a freeboard criteria for ocean-going ships, from these data I'd have to conclude that there's a good many non-ocean-going escort cruisers out there already:
