WP32 Wheelpilot 1 GENERAL 1.1 Introduction The Simrad Wheelpilot WP32 is a self-contained automatic pilot suitable for a wide variety of wheel steered sailing yachts up to 12m (39 ft) overall length. Combining highly sophisticated electronics with advanced soft- ware and a powerful mechanical drive, they are capable of pro- viding reliable and accurate steering performance under a vari- ety of different conditions with minimal current consumption. -
Page 7: The Simnet Network System
Instruction manual 1.2 The SimNet network system The SimNet system is built around a high-speed bus network- ing system, that allows Simrad instruments, navigation equip- ment and autopilots to be easily interconnected and share data. All units are interconnected and powered using a standard sin- gle cable (Fig 1.2) - WIND Tx WIND... -
Page 8: Operation
WP32 Wheelpilot 2 OPERATION 2.1 General The WP32 powers up in Standby mode, indicated by a flashing LED next to the STBY/AUTO key. The two direction LEDs above the Port and Starboard keys are always dimly lit, which provides night illumination for the keypad. All functions are confirmed audibly by a “beep”... -
Page 9: Adjusting Course
Instruction manual To lock the pilot onto the desired course, either steer the cor- rect course and then engage the autopilot, or engage the autopilot and then adjust the heading until the correct course is being sailed (see section 2.4 below). If the STBY/AUTO key is pressed and held, the pilot will beep a second time and lock onto the previously used heading (note that this feature will not be available if the unit has just been switched on). -
Page 10: Autotack
WP32 Wheelpilot 2.5 Autotack The Wheelpilot has a built-in autotack facility, allowing easy tacking of the vessel when single or short handed. An autotack is only possible when in autopilot mode. To initiate autotack, press and hold the TACK key, followed by either the Port ( ) or Starboard ( ) key, depending on which direction you wish to tack (Fig 2.4) - TACK... -
Page 11: Autotacking In Nav Mode
Instruction manual In all cases, the autotack is confirmed by a long beep, with the relevant Port or Starboard LED flashing during the course change. 2.5.3 Autotacking in Nav mode As the Wheelpilot will be steering directly to a waypoint, the autotack facility is disabled while in Nav mode. -
Page 12: Advanced Features
WP32 Wheelpilot ADVANCED FEATURES The WP32 Wheelpilot contains many advanced features, one of which is the ability to accept course data from a variety of sources apart from the internal fluxgate compass, including SimNet and NMEA compatible navigational receivers (GPS/ chartplotters, etc) and windvanes. -
Page 13: Steer To Wind
Instruction manual 3.2 Steer To Wind The Wheelpilot can sail to the apparent wind angle, rather than a compass course, using wind data via the SimNet or NMEA interfaces. Due to the faster data rate, the use of a SimNet windvane such as the Simrad IS12 Wind is recom- mended –... -
Page 14: Using An External Compass
WP32 Wheelpilot 3.3 Using an external compass Normally, the accurate operation of a self-contained autopilot is very difficult on a ferrous hulled boat (steel, ferro cement, etc), as the hull will affect the bearing read by the internal flux- gate compass. Although the Wheelpilot operates using its inbuilt fluxgate compass, it will give priority to an external SimNet compass if detected on the network bus. -
Page 15: Configuration
Instruction manual CONFIGURATION 4.1 Scaling Before using the Wheelpilot, it is necessary to program the steering sensitivity, which is related to the number of turns Setting Turns lock- that the wheel makes between end stops. This will determine to-lock (Beeps/flashes) the amount of steering correction the Wheelpilot applies. -
Page 16: Calibration Mode
WP32 Wheelpilot 4.2 Calibration mode The Gain and Seastate settings can be adjusted while the Wheelpilot is in either Standby or Autopilot mode. Press and hold the TACK key, then press NAV (Fig 4.3) - TACK TACK TACK TACK STBY STBY AUTO Fig 4.3 - Entering Calibration mode... -
Page 17: Adjusting Seastate
Instruction manual When Gain is selected, the Nav LED will flash and a repeated sequence of beeps will be heard. The number of flashes and beeps in the sequence indicates the level of the Gain setting. Use the Port ( ) and Starboard ( ) keys to adjust the Gain set- ting between 1 and 9 (Fig 4.5) - TACK STBY... -
Page 18: Autotrim
WP32 Wheelpilot 4.5 Autotrim Under differing conditions a helm bias (sometimes known as standing helm or rudder trim) is applied, in order to steer a straight course. An example is when sailing close hauled, where the vessel will normally pull into the wind, and the helmsman applies a standing helm to leeward, in order to Wind &... -
Page 19: Installation
Instruction manual INSTALLATION 5.1 Fitting the Wheelpilot With correct preparation, the Wheelpilot can be installed in under an hour. However, it is important that it is fitted correct- ly to operate to its maximum efficiency. Please read this sec- tion thoroughly before attempting installation. The pedestal mount is fixed to the pedestal using two band clamps. - Page 20 WP32 Wheelpilot 3. The exposed section of the band clamps are slotted through the sleeving provided, which covers the clip and also prevents it from scratching the pedestal when tightened. It is recom- mended that the sleeving length is reduced to approx. 25mm (1.0in) shorter than the length of the band clamps when tight- ened around the pedestal, to avoid fouling the slots in the pedestal mount.
- Page 21 Instruction manual 7. Fit the Wheelpilot to the pedestal mount by inserting the two guide rods into the slots on the pedestal mount. Check that the Wheelpilot ring is centred on the wheel shaft (Fig 5.6) - Fig 5.6 - Pilot should be central to wheel shaft If necessary, reposition the pedestal mount by removing the pilot and the front plate and loosening the band clamp.

Page 23: Electrical Installation
Instruction manual 5.2 Electrical installation The Wheelpilot operates from a 12v DC supply. The cable fitted to the Wheelpilot is used to supply the power, SimNet and NMEA data via the junction box supplied (Fig 5.10) - Junction box NMEA0183 In SimNet 12v DC Fig 5.10 - Wheelpilot junction box wiring... -
Page 24: Interfacing Via Simnet
WP32 Wheelpilot Notes: * Mount the junction box in a dry location. * No power is supplied to or from the SimNet bus – the Wheelpilot must always have its own dedicated power connection. * Use a suitable gauge power cable to run from switch panel to the junction box (see Fig 5.11, previous page). -
Page 25: Interfacing Via Nmea
Instruction manual 5.4 Interfacing via NMEA The built-in NMEA processor allows NMEA0183-compatible equipment to be connected directly to the Wheelpilot, without any need for a separate interface unit (Fig 5.14) - Wind Speed GPS/Chartplotter SimNet Wheelpilot power Fig 5.14 - NMEA integration examples If a GPS or Chartplotter is connected to the Wheelpilot, it can extract the data necessary for Nav mode. -
Page 26: Electronic Interference Suppression
WP32 Wheelpilot Because of the vast number of different manufacturers and models of navigational equipment, Simrad cannot guarantee correct operation and installation of this equipment. Therefore, before connecting any equipment to the Wheelpilot, it is important that the unit’s manual is referred to with regard to interfacing via NMEA. -
Page 27: Configuring The Wheelpilot On The Simnet Bus
Instruction manual If the rate of turn or boat speed is too fast, the Port LED will flash (Fig 5.16). Either slow the boat or reduce the angle of turn. TACK Fig 5.16 - Rate of turn too fast If the rate of turn or boat speed is too slow, the Starboard LED will flash –... - Page 28 WP32 Wheelpilot In the example shown, there are two nav data sources (the CP44 Chartplotter and the NMEA GPS via the IS12 Mega instrument) and two external heading sources (the IS12 Compass and the RFC35R Rate Compass via the AP25 Autopilot). The Wheelpilot could be used as a backup pilot, while still using the RFC35R as the heading data source.

WP32 Wheelpilot 6 APPENDIX 6.1 Advice on operation When used correctly, your Wheelpilot can maintain as good a course, on most points of sail, as a skilled helmsman, with the advantage that it never gets distracted, whereas a human can start showing lapses of concentration after as little as 10 mins. -
