For most of us a wind gauge is like training wheels on a bike. If you have learned to sail without one you do not need one. If you continue to rely on the "training wheels" that come with a chart plotter, GPS, and wind instruments it is just a matter of time before the crew gets themselves in trouble. Modern history repeats itself over and over here. You certainly do not need any of those things to move around the BVI and if you think(or know) you do you are putting yourself, the boat, and the people with you in the wrong place. Just like going too fast on a bike with training wheels you will crash. It is just a matter of time. When The Moorings opened shop the boats came with none of those toys. The original Moorings Pearson 35's chartered for $500 a week after they were sailed to the BVI on their own bottoms from New Orleans and Houston. Depth sounders were added to charter boats +/- 1975.
