ERFORM HEEL CALBRATE CAL VAL1 3 6 2 Leeway Calibrating leeway is a notoriously difficult thing to do it may be easier and as accurate to consult the yachts designer who may have a theoretical value for leeway coefficient as it is to try to measure it Should that not be possible then we can calculate the Leeway coefficient from the following formula L KxH Bs x Bs HB 0845 05 3 25 Hercules 2000 User Manual Part 3 Calibration where Bs Boat Speed K Leeway Coefficient H Heel Angle L Leeway Angle K then is the constant that needs to be entered and to establish a value for leeway coefficient we need to measure the leeway angle at a particular heel angle and boat speed shown in Fig 3 6 below Back Bearing Leaway Angle Fig 3 6 Leeway Angle Measurement The idea is to sail on a steady course and drop markers over the stern at regular intervals the angle between them and the centreline of the yacht is measured with a hand bearing compass and hence leeway angle is measured Whilst this is happening the boat speed and heel angle should be noted at intervals and an average calculated These values can then be used to calculate the leeway coefficient from the following expression K LxBsxBs H Obviously the flatter the water and the steadier the breeze the more likely this is to be successful but even in perfect conditions it is difficult to say the least Once you have the leeway coefficient K th

SOG is not the same as Boat Speed as it is referenced to the ground rather than the water which may be moving due to tidal flows and currents so SOG will not allow calculation of Tide Calculation of Wind data via SOG will actually give Ground Wind data so will appear inaccurate in strong tidal conditions SOG is also updated less frequently on the network 3 3 MEASURED WIND SPEED AND ANGLE 3 3 1 Principles of Wind Speed Angle Calibration One of the greatest problems for an instrument system to overcome which has not yet been conquered is wind shear and HB 0845 05 3 11 Hercules 2000 User Manual Part 3 Calibration wind gradient These two effects are at the root of some apparent instrument inaccuracies The effects themselves are relatively straightforward and are due to the simple fact that as moving air comes into contact with the ground it slows and changes direction The slowing creates the effect called wind gradient The change in direction creates wind shear Both shear and the wind gradient depend on the amount of mixing of the wind at ground level and the wind aloft if the wind is well mixed both effects are minimised The best example of this is the sea breeze which starts off almost completely unmixed Differences of direction of 40 50 degrees between the wind at the mast head and the wind at the water are not uncommon in an early sea breeze but as the day goes on and the sea breeze strengthens this will disappear

SS Angle Downsind Fig 2 4 Polar Performance Curve The advantage of tacking performance over VMG is that it takes into account changes in windspeed You should also be aware of the potential inaccuracies caused by your polar table being incorrect Tacking Performance has a CALBRATE option which allows you to choose a type of polar table which equates to your type of yacht In the next Paragraph Target Boat Speed we discuss polar tables in general and the implications of this choice 2 9 41 Target Boat Speed HB 0845 05 2 42 Hercules 2000 User Manual Part 2 Operating Information Menu heading PERFORM Function text TARG SPD Update rate 1 Hz Units Knots Notes 1 At Target True Wind Angle 2 Requires a Performance Processor This is the boat speed at which the optimum VMG will be achieved and can be measured from the polar table or obtained by careful analysis of both VMG and boat speed while you are sailing The Polar Table describes the performance of the boat in all conditions of True Wind Speed and Angle The Boat Speed is plotted radially against the True Wind Angle for each True Wind Speed in turn The result is a diagram as shown in Fig 2 4 Polar Wind Curve which shows the boat speed plotted for just one value of true wind speed Polar tables can be derived either by theoretical predictions the IMS certificate for instance or by analysing the boat s actual performance You may well use one of these

76. This creates a problem for the two things we are about to try to calibrate measured wind speed and measured wind angle It is easy to see how shear can affect the measured wind angle no sooner have you set it up than the shear changes and everything is out again This can lead to a circular situation if one is not careful and the best solution is to do your calibration on a day when the shear is minimal and thereafter leave it as an indicator of the wind angle at the masthead always remembering that this is not necessarily the wind angle that you are sailing at How do you know the shear is minimal If you are finding it easier to get speed on one tack than the other for no obvious reasons then there is likely to be shear A good look at the general weather conditions is also helpful Do not calibrate in building sea breezes Wind gradient is the biggest culprit for getting true wind speeds accused of gross inaccuracy The problem is that most people use the wind speed as a measure of the pressure which it is not It is a measure of the wind speed at the top of the mast and that is all If it is 12 kts at the top of the mast and only 4 at the water then the breeze will feel a lot softer and provide less power for the rig than if the breeze is twelve knots all the way down to the water HB 0845 05 3 12 Hercules 2000 User Manual Part 3 Calibration There are other signs that can help get a feel for the pressure on the rig One o
