That's a pretty subjective question, imho. Do you have a lot of experience with sailboats? If not, it's always better to have a survey done by a professional. They can find things that could save you years of frustration, or better still, make you feel good about your new purchase. If you're familiar with sailboats/boats in general, then that's a different story. Is the deck soft in any places? Is the motor covered in oil spray or does it look like it's been freshly "degreased"? What's the condition of the wiring, etc. etc. etc. The list can get kinda longish, I'd think. Ultimately, there's never any guarantees, of course, but solid homework will sure help better your odds. Good luck.
