A light air/ high performance airvane is included with every Monitor. The light air vane makes it possible to sail with a spinnaker even in very light air with boat speed down to 1 - 2 knots.
Sailors have discovered that a larger sail area works better than small in light winds and of course the same applies for windvanes. The problem is to make a large air vane that is both strong and light. Our light airvane has 60% more area than our standard airvane, yet weighs the same (one pound) and is very strong. The larger airvane will give a better signal and steer better in light wind and downwind when the apparent wind is very light. If you use the light air vane when the wind increases, you do not have to worry that it will break because we have tested it at 40 mph. However, you could use the standard airvane in speeds over 15mph.
