Go for deep draft Hunter 27
We sail a shoal draft '77 Hunter 27 on Lake Erie - we love the boat, and just finished an 8 week cruise (mostly on her) last summer. Even in the thin waters of some Lake Erie harbors, though, I would still recommend the deep draft version of this boat. At 4 feet, it still is well within your target, and will point better that our shoal draft version. Note that most builders offered shoal draft designs in the 70's, so there is no need to buy more modern to get a boat for thin water. Also, there are enough 5 footers around that marinas _will_ dredge to that draft, and as already commented, Lake Michigan itself is quite deep.The Hunter 27 is a clean, simple design, that just fits our needs. The cabin is just 6' tall, and the Admiral and I just fit into the v-berth. Our best friends, (from Rockford, IL) own a Hunter 30 on the slip across from us in Sandusky! (Go figure.) Their boat offers more headroom, and a bigger v-berth, and more complex systems to maintain.Do check out the boat reviews under "Boat Info/Model Information" on this site. They really will fill you in on the characteristics, and usual problems of the boats you are considering.If you are looking at "good old boats" from this era, I strongly recommend that you and your crew get aboard some boats now, and sit in the cabins - lie down in the berths. Picture yourself on the boat, and narrow down to a couple of models you like. Then find one in the best condition you can - a few thousand more could save you lots on initial maintenance, and rework costs. But any of these boats will offer great fun on the Lake.DavidLady Lillie
