As Killarney alluded to, you have to 'like the look'.. this one, and her bigger sister the 26 won't necessarily be the 'prettiest girl at the dance' but these boats have a solid rep and sail well. As a starter boat in BC waters you could do much worse - esp at that price.
Your pictures don't look too bad; the 'filthy' sail is mainly the result of long-time disuse and having been left furled.. it's mostly dirty on the exposed portions and the rest of it looks not too bad. New or better (used) sails would be a good (and perhaps early) upgrade.
The only pics that gave me pause were the keel bolt images, but that might just be surface rust due to standing water - still, that needs a careful look.
