Opinions if you will ..
Sail area in and of itself and ratios are just numbers without other pieces of informatiion such as length, draft, beam, displacement and waterline length, but in a general sense the boat in question would be a little overweight by modern standards (a well engineered cruiser should have a L/D around 160-180), underballasted (Ballast/disp should be somewhere around 40% or more) and not have enough sail area for light air performance or an easily handled standing sailplan (ideally the sail plan should have a SA/D above 20 to avoid a dependance on kites and larger overlapping genoas in light to moderate winds.)
You would have to figure that the rather conservative SA/D reflects a pretty tender boat unless of course if this is a deep draft boat with a bulb at which point the Ballast ratio might work OK.
There is no "Is this good or Bad?" without knowing what you planned to do with the boat but without any other info than the above, I would say that you are looking at a boat that is tender and under-canvassed making it a poor light air and a poor heavy air boat.
