How about Leaky Armor?

[Suicide Junkie]

Imagine something like a thick ring of slots around your ship. Maybe 50 slots in a circle, and slightly overlapping.
Larger ships could have a second or third layer for extra protection. Or maybe just Double/Triple strength and weight leaky armor components.

Leaky armor plating would probably be 1kt in weight, and give a lot of hitpoints; 30 to 50 or so.

These slots would not be armor slots, but would be hit first by virtue of being on the outside.
Since there are 50 of the slots, it will be relatively easy to punch a hole by destroying two or three adjacent slots.

The "armor" would be repaired like hull components, (since its not technically armor) but would likely need to be left at priority #9
