Wow- last week you were looking at a Mirage 24, this week a Sonic 23.
First boat, huh? You're as unfocused as a virgin with ADHD and access to a trust fund on his first visit to a whorehouse. What, exactly, do you want to do with your sailboat? Race? Cruise? Both? What is your budget this year, including initial purchase, maintenance, mooring, and unexpected surprises? Where do you plan to sail? Who do you plan to sail with? What kind of creature comforts do you want? I say, boy, I say, focus, boy, focus!
