Sloop seakeeping depended strongly on size

How well did sloops keep station at sea compared with the rolling Flower-class corvettes?

Larger sloops could be good sea boats, but the smallest Kingfisher-scale designs were unsuitable for heavy seas.

Not every sloop had the famously lively motion of a Flower-class corvette. Larger designs at the upper end of the category could behave well at sea. The roughly 518-ton experimental end of the spectrum was much less suitable for a heavy swell.
