Tudy,
You guessed it - I use a Vermont Castings Encore!
As for the boat you describe, I'm not much of an expert on older cats, but you've sure come to the right forum to find someone who'll be able to figure it out for you. As for sails, does the boat have a jib? Or just a main?
Then there's the age thing. At 54, you're in your prime! Go for it. Sailing on the more protected waters of the small lakes in Waseca (a mile or so across) will be a good place to start. One of the early challenges will be learning what to do in the event of a capsize and righting the boat by yourself.
