Interactive cloth, tear but not on move?

Hi,
I’m trying to use cloth for the sails on a ship. I’d like to have the cloth tear when hit by a cannon ball but not when the ship moves. Problem I’m having is that if I set a tear value and the ship moves quickly the cloth rips apart.

Anyway I can make the transforming the cloth not make it tear so it only can tear when hit?

Still stuck on this. Any ideas?
