Indeed a great thread.
Carl has, in #55, my vote for the ugliest boat so far. It is a little known fact that the Hickman Sea Sled ( a much smaller but more handsome boat) way back when was the precursor to the Boston Whaler, late '50s-early '60s?
And the Sea Ray in #56... oops, WATCH OUT! Don't step in the puke that Connie Ray just left behind!
