Why a Skjold-class North Atlantic crossing would be punishing

Could a Skjold-class corvette cross the North Atlantic with frequent refuelling?

The crossing is possible, but the class's relatively flat hull form makes it poorly suited to North Atlantic motion and very uncomfortable for the crew.

Frequent refuelling can solve the Skjold class's range problem, so the ship could make the passage in principle. Its relatively flat bottom suits a different operating environment and would produce a punishing ride in the North Atlantic. The crew's ribs and tailbones would bear the cost of that hull form in heavy seas. Endurance figures alone cannot establish whether a ship is effective for an ocean crossing.
