Developmental Analysis

  This page will give you an idea of the skills needed to participate in sailing.  This will also give the students cues for each
              skills.  The developmental analysis will give the instructor the correct progression to teach his or her students about sailing.






 Skills                                                      Keys to Success                                     Effective Drills
Getting to Know the parts of the Sailboat Parts of the Sailboat Handout Sailboat Name Game
Students will get into groups three or four depending on how many models you have in your classroom.  Then each group of students will be given a model.  Each partner will be asked to name the different parts of the sailboat. It should be stressed the importance of knowing the different parts.
Which way is the wind blowing? Ways of telling which way the wind is coming from.
      a.  Look to see what the wind does to flags, trees, smoke, and your hair. 
       b.  If the wind is barely blowing see where the birds are perched they always face the wind. 
       c.  Look at the water wind creates ripples which make the water darker. 
Wind direction search
Have all of the students go outside and name two different ways to tell which way the wind is coming from.
Safety Safety tips 
Listen to the local weather forecast. Bad weather and high seas can be very hazardous even for the experienced sailor. You will learn over a period of time through experience and reading books on how to handle unexpected bad weather. But for now, only go out when the weather is favorable for pleasant sailing. 
Know the waters you are sailing on.  Ask questions concerning local regulation rules, navigational aids, hazardous rocks, strong currents etc. Ask an experienced local sailor about conditions or hazards you should know before venturing out. 
Leave a float plan. Let someone know where you're going and when you'll be back. Then, when you're back ashore, cancel the float plan by letting the person know you've returned. 
Safety 
Give the safety handout and lecture.
Sail zones and no sail zones Examine the sail zones Creation of the wheel
Students will get into groups and create their own wheel of sail zones.  This can be done in any way.
Life jacket fitting
Tieing Knots Examine the Knot tieing page Partner Knot tieing
Partners get together and tie different knots on a cleat.
Environmental Concerns Examine the environmental handout. Environmental Concerns
The instructor will lecture on the topic of environemental concerns
Understand how the sail works
How it works
As wind approaches the leading edge of the sail, it separates and flows along both sides of the sail from luff to leech. The air on the windward side reaches the leech first, since it has a shorter route to travel. The results is lower pressure on the leeward side of the sail creating a lift perpendicular to the wind. 

Another way to look at how an airfoil works is the wind on the outside curve is spread out, so its pressure is lower. The wind on the inside piles up, and its pressure is higher. The result is that the high pressure inside pushes on the sail, while the low pressure outside creates suction. Together they make a push-pull effect that drives the boat forward. 

The push-pull action drives the boat forward and sideways. The centerboard or keel prevents the boat from slipping sideways.. 

Notebook Activity
 Taking a piece of notebook paper and holding it up horizontally by the two corners in front of your face. The far edge of the paper will drop down because of gravity. Now blow hard along the top surface. The paper will be sucked back up to the horizontal. Your sail works in the same way.
