Well...



Actually, this type of ship would also be very attractive on the export market. Many navies have a need for a decent boat that can make oceanic trips but would mostly be deployed in the local littoral zone, and have respectable armament.

They need to take crew comfort into account in wartime, since a bone-tired crew can't fight with their ship effectively if they haven't had a chance to get enough rest. This is very, very important in wartime periods. Well, in wartimes, a ship has to make do with what needs to be done. The NATO ship wasn't at war, so if they didn't need to sail in a storm, they probably wouldn't.

This article indicates the Canadian Flower Class Corvette was a very small, reliable ship that was way uncomfortable to sail on. The top military brass doubled the crew strength to allow off-duty crewmen enough rest to function. Even so, I have a picture of a Flower Class ship making slow headway into big ocean swells while the foredeck was being washed over by breaking waves across the port or starboard bow. They didn't sink, but they weren't fun to sail in a storm. Right. 80 degree, full side-to-side rolling moves from vertical were described in the Wikipedia article---for that class of ship. The American Buckley Class destroyer escort(essentially a small frigate/large corvette) had at least 50%-75% more displacement than the Flowers. The newer ships were more seaworthy.
