you have a long road ahead
I'm not sure what condition your boat is in from your post. It sure sounds like the interior is trashed from the weather/acorns/nests/etc. How is the exterior? Any cracks? Any rust? Does the deck hardware work OK? When you rub your finger over the hull, does it leave a white chalky deposit on your finger? Since it sounds like the condition is below average (due to being neglected for 7 years) and since you're missing some parts (mast step, sails), I would say the boat is probably worth $2000. However, I need to warn you of how big a job you have ahead of you, depending on your standards and goals. Just to get it operational, you're probably going to be spending $1000 and 6 months of weekends. And that's if you just ignore the interior. Are you a fairly experienced sailor? Have you owned/maintained a sailboat before? If you answered no to both questions, I think you might want to consider finding a boat in ready-to-sail condition instead of the one you have. The learning curve is very steep for a newbie trying to restore an old boat. On the other hand, if you have the gumption to stick with it through the hard work and long hours, then it'll be a very rewarding project. I had no idea how much work and money I'd end up spending on my 1982 Mac 21. I still haven't been able to sail it much after 18 months of owning it. But then again, I want it to sail better than it did when it came out of the factory. If you just want to sail, period, then see the time and money estimate above. Before I bought my boat and started realizing how much work even a "good condition" boat needs, I wondered why people shelled out $20k + for a newer boat this size. Now I know. If I had ponied up the dough, I could have spent 95% of my time sailing. But instead, of all the time I've spent on my boat, more than 95% of it has been spent on maintainance and refurbishing. New sails from a good sailmaker will cost you ~$1200. Cruising Direct is a good source for cost-effective quality sails; http://www.cruisingdirect.com . Used sails can save you 50% or more, but buyer beware. The performance and ease of handling of used sails can be significantly less than 50% of new ones.
