    This display is now set to ignore any alarm function. TRIP FUNCTIONS The Hercules 2000 provides three trip functions: Timer (count-up and count-down), Trip Log and Dead Reckoning. The functions can be reset and restarted as required, e.g. for keeping a separate log of elapsed time and distance run for a given passage.

  • Page 42: Race Timer

    Hercules 2000 User Manual Part 2 - Operating Information When any trip function is started, all other trip functions which have been reset start simultaneously, except when the timer countdown is started. Under this condition, the other functions start, again if previously reset, when the countdown reaches zero.

    Hercules 2000 User Manual Part 2 - Operating Information (5) When the timer reaches zero, the counter starts counting upwards. Selecting START in this condition resets the counter to the SET value and starts counting down again. When STOP is selected, the timer stops at whatever value is currently displayed.

  • Page 44: Lighting Control

    The level of illumination at system displays is controlled by the Power Lights Key. Use of this key normally controls all the Hercules 2000 displays simultaneously. However, the level of illumination on a single FFD can be controlled individually under the menu choice - LIGHTING - LOCAL.

    OPERATING FUNCTIONS We have seen how the Hercules 2000 System is built up and how the key and menu system operates. Here we will describe each of the functions in greater detail, to see not only the information they provide, but also some of the ways this can be employed on the boat.

This incorporates Leeway into heading and is sometimes called Course Made Good. Leeway can only be calculated if you have the heel sensor fitted, but Course is the preferred function for most navigational purposes and should be used when possible.

    Hercules 2000 User Manual Part 2 - Operating Information Cross Track Error indicates how far you are from the direct (Rhumb Line or Great Circle) as a perpendicular distance and allows you to correct even the slightest deviation. Although this may not be the objective, on long, tidally affected legs you will plan to be swept first one way and then the other.

  • Page 57: Heel Angle

    Leeway is the angle between the boat’s heading and course through the water. The difference is caused by the sideways slip that the boat has when going upwind. For the Hercules 2000 to be able to measure this it needs to know the heel angle, and hence a sensor must be fitted.

    Hercules 2000 User Manual Part 2 - Operating Information Function text: LAYLINE Update rate: Provided by position fixer Units: Nautical miles Note Requires NMEA 0183 interfaced position fixing system transmitting the ZDL sentence. If tacking upwind or downwind to a waypoint, some position fixing systems will provide layline information based on a pre-defined tacking angle (usually adjustable).

  • Page 60: Next Leg Wind Information

    Should the leg be upwind or downwind, rather than free, the Hercules 2000 calculates on the basis of the true wind angle for the optimum VMG on the advantaged tack; this is indicated by the position of the small bar at the top or bottom of the digits. The tide calculated by the Hercules 2000 can be applied to the calculation if required.

  • Page 64: Stored Log

    Hercules 2000 User Manual Part 2 - Operating Information This is most useful in races such as the Newport-Bermuda, where the ocean currents are critical to the tactics. Changes in sea temperature are good indications of ocean current. Sea temperature can be useful in other ways too; water flowing out of rivers differs in temperature quite markedly to the sea, and this can assist in choosing a favourable current.

  • Page 65: Tacking Performance

    Part 2 - Operating Information Notes 1. Requires Performance Processor. The Hercules 2000 calculates the optimum VMG from the polar tables for the wind speed and then compares this to the VMG actually being achieved, displaying the result as the tacking performance percentage.
  • Page 66 IMS certificate for instance, or by analysing the boat's actual performance. You may well use one of these techniques to obtain your polar table, however, if you do not, then the Hercules 2000 has one polar table already stored in its memory. A copy of this polar table is shown in Table 2.1 on page 2-47.

  • Page 67: Target True Wind Angle

    Hercules 2000 User Manual Part 2 - Operating Information performance, optimum wind angle and target boat speed, as well as the predictions of next leg. We can see from Fig. 2.4 how the target boat speed is obtained from the polar tables. It is the point at which a perpendicular drawn to the 0 degree true wind angle first touches the curve, hence optimising speed in a windward direction.

However, it is not possible for the helmsman to sail to it directly because of the momentum of the boat.

    As an absolute minimum your system should measure these four parameters. There are many really useful additional values that the Hercules 2000 allows you to measure, but they are not essential to the system's primary function.

    The boat speed/log calibration value is always shown as Hertz per knot (Hz/Kt) The Hercules 2000 allows for calibration of a port and starboard log, as well as a single unit. There are occasions when you will need to calibrate each tack separately e.g.

    Hercules 2000 User Manual Part 3 - Calibration to their mechanical nature, they are likely to over-read and require correction. An Ultrasonic sensor is linear in its response and does not require significant correction. Heel Angle corrections apply to all types of sensor and are actually due to the change in water flow patterns over the surface of the hull rather than the sensor characteristics.
  • Page 88 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.

  • Page 89: Measured Wind Angle Calibration (Mwa)

    Hercules 2000 User Manual Part 3 - Calibration There are other signs that can help get a feel for the pressure on the rig. One of the most important of these is the heel angle; it is no bad thing to have an idea of how much heel you normally have in any given windspeed.

    Hercules 2000 User Manual Part 6 - Diagnostic Data (d) The transducer is receiving extra reflections off an adjacent pontoon or jetty. (e) The transducer is receiving interference from another B&G system located in an adjacent yacht. (f) The transducer is faulty or has been damaged. The transducer should be checked for any damage, barnacle growth or thick layers of paint.
