I've been looking around for a used Macgregor 22 or 24. In my internet travels, I've been in communications with someone at a Mac dealer her in Seattle that said they may have a trade-in boat coming any day now. No photos of the boat yet, the women that I've been emailing said she was concerned that the boat might be "icky" which is why the owner may be slow to send photos. She told me that I should watch out for Macs without a keel (obviously) and make sure to examine the keel carefully since they aren't made anymore. She said watch out for seized keels that don't move since the lead inside the fiberglass may have "swelled" and jammed the keel in place. So, what is there that I should look out for? I figure when I examine boats I'll just start from the bottom - check the keel, tap on the hull and check for delamination...etc then work my way up until I've reached the top of the mast. What exactly are the keels made of? Are they a chunk of iron, lead, do they have a fiberglass coating...? What should I be checking? Do they get rusty and covered with salt water crud that should be aware of??Tom- Seeking my dream ship
