Too many factor involved to give a meaningful answer.

Banging and Slugging around a 1000 kg lead keel is sure as hell putting a lot a stress and strain on mono contruction as well.

And the fashion these days is to make monohull racers with relative flat keel lines to get them planing. These vessel are far removed from the classical working boats that could survive petty much anything. Both the mono's and the multis'

But again to main idea was to not be at the spot where the [censored] hits the fan.
