Sailing Simple Pole Adjustment Construction and Tricks

Simply Setting A Pole

Sailing boats need to have accurate direct settings in order to improve their sailing performance and navigate safely. In our technical article, we simply discussed the techniques of setting directly.

First, we're going to need to know two terms correctly.

* Rake : The bending of the mast is called leaning backwards without bending, spraining.

* Bend: The sail pole is called spraining and yawning under the influence of forces.

The Backward Reclining of the Mast / Rake

The backward reclining of the sailpoles provides the most important privilege in races and orsa performance. But there's a limit to his flatness. Under normal conditions, in double-gurcata monolets, the recommended backwardness of the poles is around 2 degrees. But increasing this angle in harsh weather will affect the boat's orsa performance in a very positive way.

The tricks for rake are that in mild windy weather, to catch the wind above the sea sequencing, it is necessary to reduce the backwardness (rake angle) and to move the mast forward. In severe weather, it is necessary to reduce the angle of the rake and make the mast steeper in order to both miss the wind a little and increase the performance of the orsa. The tilt of the mast on many cruise and racing boats cannot be arranged during the cruise. So an optimum adjustment should be made, or fine-tuning according to the weather on the morning of the race day.

 

Rake / Making A Direct Flatness Adjustment

Sailing boats can not be adjusted rake in the mediocre area, i.e. with the crucifixion wires holding the mast from the sides. By adjusting the adjacent crucifixes and the diagonels above the gurcata, the slope, i.e. bend adjustment, can be made. To make rake, the head of the scaling wire had to be extended and shortened. If you have a lift set on the head scaling wire, it is easy, or it is difficult. Moving the mast base is also necessary for the tilt adjustment. By taking the moving mast base back and forth, a direct trim can also be made.

 

Calculating Rake

In order to make an accurate calculation, the ropes attached to the boat need to be loosened. In particular, the head vault of the boat to be measured is not too tense, the aft palapers are not too tense, the weight balance of the boat should be normal.  The weather should not be choppy and windy.

We'll also need the measurements of the main mast. In particular, we need to know the "I" measure of the mast. Our goal is to calculate the reclining of the mast with the help of the main sail mandar. At least 7-8 kg of object should be hung on the main sail latch and free movement should be ensured. Buckets full of water, hand tools, etc. Can.

From the back end of the main mast, the point at which the mandar rope cuts on the boom should be measured. It usually has a value of 40-50 cm. The ratio of this value will give us the rake, the backward ness.

We'll use the triangular formula to find the rake angle.

I/B should be done as seen above. The result should be reversed by tangent on the calculator. Then the mast will be leaned back.

Eg

I = 16 meters = 1600 cm;

B = 50 cm.

50/1600 = 0.03125

Tan -1 (0.03125) = 1.78 degrees straight back.

 

Crucifixion Wires and Direct Tension Adjustment

The easiest way to observe this is in an air (TWS) with a real wind speed of 10-12 knots, and in the course of the orsa, the underwind crucifixes must be slightly discharged. Not too much to swing, it shouldn't be as tense as staples. For this purpose, 18% of the breaking force of the wire will suffice.

The easiest way to understand this is to die with a blood pressure meter, but otherwise you make an eye decision. When you hit the crucifix, a slight tin should sound. If there's no sound, the crucifixion wires are too empty. Direct producers indicate that the maximum blood pressure should be 20%.

By setting the crucifixes and the crossed dioganel wires above the gurcata, you make a direct inclination (bend). The mast should never, ever tilt forward, i.e. pre-bend.

Direct Slope (Bend) Setting

The area where the mast slopes must be close to the top of the mast. Starting just from the bottom of the first gurcata, stretching slightly forward, reclining backwards is not suitable at all. The backward inclination should usually start two metres above the first gurcata or after the second gurcata.

Tip : Excess bend is for harsh air, bend should be reduced in light air.

 

Calculating Rake Correctly

If the bend, i.e. the tilt back, is too high, the rake value will also be incorrect.

To accurately measure Rake.

• The ass should be emptied in the ass.

• There should be no overload on the crucifixion wires.

• The boat must be balanced.

 

 WARNING – Direct checks should be performed every season

The masts of sailing boats should be checked by authorized persons at the beginning of each season. Unfortunately, the number of professional people who can do the direct trim of sailboats in our country is very small. Therefore, do not hand over your poles to unauthorized persons.
