My buddy had a Ranger 33 as his first boat and enjoyed it. I have a Viking 33...they are quite similar in the specs and the general '70s racer-cruiser design mindset. Bolt through plexi or Lexan portlights are quite common and when installed well (bedded securely and the boltholes through the...likely...balsa core have been given epoxy "donuts") are probably better than the original butyl-tape gasketted aluminum frames.
The Ranger 33 used to be on the big side of middle and is now on the big side of small , but if it's fair, it's still a good windward performer and a very nice size for a couple. Just watch for old dangerous crap like frozen gate valves over the thru-hulls and rotted mast steps or dodgy original standing rigging.
