Boats that use the system
- Cruising and racing multihulls, e.g. Orange
- Shorthanded and single handed racing yachts e.g. B&Q
Yachts in this class require certain specifications
- The ability to accept speed inputs from each hull and calibrate them differently
- Functionality to account for mast rotation in wind measurements
- Facility to correct errors in boat speed linearity at different speeds
Benefits of this system
- CPU will automatically select the optimum speed sensor based on user choice of wind angle or heel angle
- Mast rotation sensor adjusts measured wind angle to correct for rotating masts
- Gyro-stabilised Compass and race-bred Pilot steers multihulls to heading, true wind angle or apparent wind angle
Complimentary hardware and software
- Deckman software can be used to great effect to call laylines and times to marks when racing at high speed
- Additional linear inputs can be used to measure daggerboard positions
- Faster racing multihulls should consider the WTP2 processor for faster and more accurate wind information
Recommended Simrad equipment
- RS82 VHF
- HT50 Handheld VHF
- SA50 SART
- RA30 Radar
Tips
- Use RemoteVision to control Pilot and check data when moving around the deck area or whilst sailing shorthanded
- Use Pilot in true wind mode when sailing fast downwind as the apparent wind tends to vary causing large course variations
- Calibrate port and starboard boatspeed inputs at low speed by motoring and use the linearity tables in Hercules to correct the over-reading at high speeds
- Ensure that there is a direct relationship between mast rotation and the sensor such that the sensor and mast rotate at the same rate
