I have a 30 which I bought about 15 months ago. Love it. Plan to sink some money into it, but don't delude myself that I can recover the costs. This boat loves to go to weather it is strong, we've been out 40 mph winds and she has handled them with grace, far more than its crew.
The YSB 12 is grossly under powered. Not a problem without strong currents but we went out on Delaware Bay early this fall and the engine wasn't really up to the combination of unfavorable wind and a fast current. we'd tried to time coming down with the current and getting to Cape May with slack tide, unfortunately for the first half of the trip there was no wind and it took much longer than planned.
As to the bottom, mine had not been pulled in four years when we pulled it for the survey, the surveyor kept warning me not to be shocked by blisters. To his amazement there weren't any and I have been told these hulls were made reasonably early in the adoption of fiber glass and they tended to be generous with resin and there aren't a lot of blistered bottoms.
If you want to see her under sail on the Cape May run, check out the video on You Tube
