This document, which Larry provided the link to, contriticts you with actual

See damage distribution graphs. There will usually be some damage and some
strikes will overwhelm any system. However, saying protection is pointless

crashes will be fatal anyway.

Everything on the water is about odds. Stack the deck in your favor when
you can.
