Re: Sirocco 15 daysailer a good first "real" boat?
I don't know the boat but it looks quite okay considering age, and the mast looks decent from what the photos show.
I vote, go out and have fun with her. 19 chances out of 20 those are just surface gel coat cracks/chips to be ignored. Looks like a three-stay rig, nice looking line drawing and blood simple so no hidden disaster areas.
Take note that 80 pounds does not really a "keel" make, it's basically a heavy centerboard. that said, no reason it shouldn't sail well, just use your weight placement to make up for the lack of weight in the "keel". And keep weight forward, with that faux cabin it's easy to sit too far aft and drag the stern, which will slow you and affect handling.
Good luck and let us know how it turns out.
