48° North - Feature Article
Looking at the top picture on the right hand side. The white Tbird "Rev" is still sailed competitively, and does very well. The red one to the right, appears to be "Flair" out of my club, still raced, and does well. I have a fit with both at times, as we are in the same class. I have them by 5-10 secs, but they are always just in front for Rev, or either direction for flair. Rev is dry sailed, Flair is wet, ie always in the water. Flair way back finished in this magazines top 25 boats in Puget Sound with current owner.
