Question

How much larger would a Flower-class corvette need to be for two shafts and two reciprocating engines?

Short answer

About another hundred tons, using the two-shaft Bathurst class as the nearest comparison.

Notes

The single-shaft Flower and two-shaft Bathurst classes provide a rough comparison for adding a second shaft and engine. The Bathurst is quoted at 1,025 tons full load, while figures of 940 and 1,031 tons are given for versions of the Flower. On that basis, another hundred tons is estimated for a Flower with two shafts and broadly similar capability. It is an approximate comparison between existing escort designs.
