Fall Line: 2. When you reach the point where the anchor is to be lowered, you should have steerageway, but no more. Shoot the bow directly into the wind, let the sheet run, and drop the sail. As the Boat loses headway, her bow will fall line off and the Boat will begin to drift to leeward. Now lower your anchor.
3. As the Boat drifts back, pay out scope. Occasionally give a few jerks on the line; this helps to set the anchor. Hand test the line by pulling it. Your anchor will be holding when the Boat is drawn toward it as you pull on the line. Pay out the usual scope of approximately
Make certain that the tops of each pair of stakes are perfectly level.
If you use a line level, the pairs of stakes may be 20 feet apart. On top of the stake that should be lowest place a block of a thickness equal to the difference in heights between successive pairs of stakes (one and two tenths inches if the fall line is to be six inches per 100 feet). Stretch a thin line •with line level hooked at about its center between the top of the block and the top of a stake of the next pair farther up the line. Read the level. It should indicate that the top of the block and the top of the stake are level. If it does not, adjust the upper pair of stakes until they are level.
Semilogarithmic paper distorts the y-axis so that, when locating a I/value, the actual length found is proportional to log y. Hence, the graph of y = ab* will be a straight line. If data are suspected to be exponential, one can simply plot the data on semilogarithmic paper. If the points fall line on a line, the relation is exponential.
