My V21 got its name from my screen name - Blue Runner.  My screen name came about in July of 2003 when I joined my first message board ever - 
www.reddrumtackle.com - which is a tackle shop on the outer banks where I used to surf fish some.  
 
Just prior I had been surf fishing at the OBX and caught two strange fish that I could not ID.  It turns out they were blue runners.  I ate them (along with a bunch of croakers and sea mullet) before I even knew what they were.  Looked like a bluefish to me, but tasted better LOL! 
 
My first boat was named Cash Money - because that's what I paid for it - $900 clams.  And a fine boat it was.  Pictures in my gallery.
