- Participants must assume the responsibility for whichever activity they are participating in: either ATV riding or Land Sailing.
- Use them at your own risk and only if you can take this responsibility.
1. HOW TO USE A LAND SAIL SAFELY:
• Always wear protective gears: Proper shoes covering toes, a helmet and preferably gloves.
• Put on your seat belt.
• Do not go faster than you feel comfortable and never exceed 25 miles per hour.
• Ride very slowly to familiarize yourself with the controls: steering with both feet, brake by left hand, controlling the sail by pulling the rope with right or both hands.
• Practice turns. Always turn into the wind. Never turn into downwind as it will flip and cause a mess in the sail.
• Slow down to comfortable speed before you initiate a sharp turn, or turn very widely so as not to tip the land sail and yourself.
With the land sail, you can travel into every direction, even towards or against the head wind. But to do so, you need to zig zag into the wind. You cannot go straight into the wind. Read below and see the Figure 1 and 2. (SOURCE: Wikipedia)
HOW TO GO AGAINST THE WIND?
A land sail can be 'worked to windward', to arrive at an upwind destination, by sailing close-hauled with the wind coming from one side, then tacking (turning the boat through the eye of the wind) and sailing with the wind coming from the other side. By this method of zig-zagging into the wind, known as beating, it is possible to reach any upwind destination. A yacht beating to a mark directly upwind one mile (1.6 km) away will cover a distance through the water of at least 1.4 miles (2.3 km), if it can tack through an angle of 90 degrees including leeway. An old adage describes beating as sailing for twice the distance at half the speed and three times the discomfort. .

HOW TO GO FASTER THAN THE WIND?
Sailing faster than the wind is the technique by which vehicles that are powered by sails (such as sailboats, iceboats and sand yachts) advance over the surface on which they travel faster than the wind that powers them. Such devices cannot do this when sailing dead downwind using simple square sails that are set perpendicular to the wind, but they can achieve speeds greater than wind speed by setting sails at an angle to the wind and by using the lateral resistance of the surface on which they sail (for example the water or the ice or land) to maintain a course at some other angle to the wind. The Extreme 40 catamaran can sail at 35 mph when the wind is 23 mph. The high-performance International C-Class Catamaran can sail at twice the speed of the wind. Iceboats can typically sail at five times the speed of the wind. By sailing downwind at 135 degrees off the wind, a sand yacht can sail much faster than the wind. The velocity made good downwind is often over twice as fast compared to the same land yacht sailing directly downwind. The catamarans that will be used for the 2013 America's Cup are expected to sail upwind at 1.2 times the speed of the true wind, and downwind at 1.6 times the speed of the true wind. In 2009, the world speed sailing record on water was set by a hydrofoil trimaran sailing at 1.71 times the speed of the wind. Also in 2009, the world land speed record for a wind-powered vehicle was set by the sand yacht Greenbird sailing at about three times the speed of the wind.
Figure 2: What is the best sailing angle?
The angles between C and B in the figure above provides the fastest speeds. When you sail at these angles, you will go faster than the wind. This is the magic of sailing. When the wind is 8 mph, you can easily go about 12-16 mph or more. In fact any direction other than no go zone that is marked with red stripes and straight downwind should be faster than the wind itself. When you go down wind you can only go as fast as the wind.
2. HOW TO RIDE AN ATV SAFELY:• Walk around the ATV and familiarize yourself with the machine.
• Check the tires and other visible parts to make sure everything is good and safe to operate.
• Learn where all the controls are: Brakes, steering, throttle. Check to see if they work fine.
• Use proper footwear, toes and ankles protected.
• Wear a helmet.
• Never ride someone else with you on the same ATV.
• Ride safe and slow, familiarize yourself with how the vehicle is responding and behaving.
• Do not test your limits by going fast or turning sharply. Enjoy it nice and slowly.
