What Boat Replaced The Sunbird?

Thread starter #1
I have sailed Sunfish many times, but its not big enough for my wife and 2 boys. I know the Sunbird is no longer made (I think) and I am looking for a new boat about the same size as the Sunbird. What boat would you recommend for taking the fam on a lake and to enjoy the day. Don't want anything too big, but just big enough for 4 people. I prefer a 2 sail vessel as well.

After doing some searching on the internet, it looks like a Vanguard 15 might be a good option. Not sure if 4 people would be too tight.
