How capable are 21' boats

I have a 1978 Buccaneer 210. (I know, not the quickest, least tippy, best pointing boat) it's great for my wife and child to take out though.

We just purchased it about a month ago. I haven't sailed in 20 years but used to be competitive.

We will of course build up our experiance on this boat but what are some reasonable expectations for wind and wave tolerance on this thing?

It's in good condition. Well taken care of. 1 owner before me.
