How to interpret "Stability Category" certificate ???
 

Hi Folks, I have in possession a copy of a sisterships "Sailing vessel
15M Stability Category" certificate, issued by The Committee of the
YBDSA Certifying Authority (Australian??). Anyway, we own sister

displacement with 3260 kg ballast. LOa 11 M, beam 3.38 m, lwl
8.617 m, DCB 0.842M (????).

My questions is how do I interrept the info quoted below?
