The VS mainsail won four of the last five Nationals. It is a very pleasing sail to trim and is exceptionally smooth. While slightly flatter down low than the DSD, it is full and powerful up high for true all-around performance. It is a slightly more mainsheet sensitive sail and due to its lighter, stiffer fabric reacts quickly to changes in wind velocity. The VS main responds well to vang sheeting, so it is an ideal choice for Thistlers who are comfortable with vang sheeting when sailing in bigger breeze.
