So what happens to the raft over time? It seems to be pretty secure in its fiberglass case, protected from UV. What else deteriorates?

I have a 30 year old liferaft that came with my boat. There's no way it can be repacked, I'm guessing, so it's a very expensive chunk of ballast at this point. So, I've been wondering what to do with it. My longest planned offshore trip will be to the Bahamas so I really don't need the raft, but it seems like a shame to just toss it. I could keep it and if my boat started to sink half way to Georgetown see if it would deploy. Or, I could have some fun with it and launch it here at the marina to see what would happen.

The last option would be fun.
