Skeg / Fin question

I recently used an AIRE kayak with and without the optional short skeg attached. (Class I-2 river with lots of turns).
I was very surprised how much the skeg improved the kayak’s performance and handling! Noticeable after only a few strokes.
The kayak tracks better and surprisingly carves turns better.

It’s pretty much a guarantee I will ground out on the occasional shallow spot.

My. Question:
How durable are skegs?
(6 inches or less)
When they break can I expect the mounting base to remain intact?

Any feedback is greatly appreciated,
Thanks!
