With out a doubt buy the Seafarer. It is a stiff and very stable well manered and well made boat.It was designed by Mc Curdy and Rhodes. They were all hand built, not cookie cutter boats. I have three boats at this point and my seafarer is unquestionably the best sailor of the three.
The Pearsons a good boat but a little tender for me.
Which ever boat you purchase make sure to get a survey. No boat is perfect.
