Thanks Thom, I probably asked the wrong question. Lets rephrase it: to what extent is it correct to call "Farriers" the recently constructed Corsairs derived from F-Boats?

Mathematically and legally, if they changed ANY detail (and we know they did it), it is not his responsibility anymore.

Naturally one can use the F31 figures from the website as a reference (to discover that questioning the F31 stability is ridiculous...), but one can not be sure that today's Corsair 31 will behave as predicted for the F31.

And before you ask: five and a half years and counting. Folding system operational, mast half rigged, sails follow next.
