The regatta elements kit contains three wind direction arrows and one wave/tide arrow, each 8.5 x 3.5 cm in size, and one 360 penalty marker. The wind arrows are of three different colors: red(port wind shifts), blue (main wind direction) and green (starboard wind shifts). Each element comes with an embedded magnet which makes it easy for elements to be used on a whiteboard for example. The regatta elements kit makes for a great addition to your race and coach kit.
