I'm aware that the Oyster was about twice the displacement of the
Beneteau, so the inertia stresses on the Beneteau rigging would
have been higher (all that bouncing around!).

=============================================

Perhaps not. The most important predictor of rigging stress is
righting moment (resistance to heeling). A boat with a higher
righting moment can carry more sail for a given wind strength, and
consequently has higher rigging loads.
