ALL- Thanks for the information and advice.
Jeff-I am told that Lake Monroe has some fairly shallow areas, so the centerboard suggestion may be a better fit. Thanks!
Don- Thanks for the suggestions. Yes, I would like to find a boat with decent headroom as I am 6'1", but have heard that I will have headroom issues with most boats unless I move up into a longer boat. I'll look for the book you suggested.
Andy- Thanks for the feedback on your Aquarius.
So far I am not having much luck on-line searching within 2-3 hours of Indianapolis, but will continue my search. I was hoping to find a great deal on a boat during the off-season.
