I'll second the Kent Ranger 20 as a great boat, I currently own 1 and have owned another. They are local for you (100 miles) and close for dad. They sail very well, weigh 1550 lbs. and trailer great. 1 healthy person can set the mast in place and be sailing from trailer in 30/45 minutes. Active forums both here in Seattle, and in Portland, with at least one active Sailmaker, and several of the original vendors still at the same addresses that they were when the boat was built. Approx 700 boats were built with some even being built in Salt Lake City.
Mine is in the water, If you or dad want to see it, let me know....They come up for sail on the Forums/Craigslist but you have to be fast, as they sell quickly. After the snow stops/melts I'm willing to go for a sail if you are interested. I'm on Lake Washington, near downtown.
Let me know
