Thanks for the response Jim. Lake Manitou is 40 square miles. There's a tiny island about 200 feet from our shoreline, and there are other small islands as well, which makes them islands in a lake in an island in another lake. Or something like that.
Mostly I think I'll be staying within my small lake, and if I venture out into the great lakes it will be after my skills are more honed and I'll require an upgrade. I was also looking at an O'Day Daysailer II, and a 14 foot Sunfish.
