Hopefully there was more to the survey than what you posted. At first I thought that is the saddest survey ever, but then it occurred to me that you may have only posted part of it. If that is all you have, ask the broker for the rest of the survey.
If what you posted is the whole survey, you should get your own survey performed (by someone different, obviously) if you are really seriously considering purchasing this boat. Catalina changed things with the 30 over the years, different model years of Cat-30's have different characteristics so get a surveyor who knows this model.
Also, if the broker presented that one sheet as a complete survey, you might think twice about him/her, too.
