1. SAILING REGATA BRIEFING in Barcelona EventOrganised by: Dreams & Adventures www.dreamsandadventures.com

2. 2 3. 3 Basic understanding of how a sailboat works. Boat direction is not always equal to wind direction. Aerodynamics and hydrodynamics. 4. 4 Centerboard or keel underneath the hull. The flow of water over the underwater surfaces creates a sideways force, countering the force of the wind. The boat is pushed forward by the combination of these forces. 5. 5 Form stability and ballast prevent capsizing. The keel is weighted, pulling the boat down. Centerboards are not weighted, so the crew must use their weight. If the crew does not use their weight, the boat can capsize. 6. 6 7. 7 The movement of air from areas of high pressure to areas of low pressure. It is stronger where there is less resistance. The wind is constantly changing in both strength and direction. It is important to be aware of the strength and direction of the wind. By doing so, you can harness its energy efficiently and sail safely. 8. 8 There are several ways to determine the direction and strength of the wind The most accurate way: ripples on the water s surface. Strips of nylon tied to the shrouds and backstay. A masthead fly, with a wind arrow. The luffing of the sails. 9. 9 Whitecaps: 12-14 knots. Small boats become unstable. Inexperienced sailors should not be out alone. 10. 10 11. 11 Eyeball navigation. Compass.
