2. WHISPER POWER“ The new way of yachting life” BMEA Annual Conference 2010

4. Product &Concept Design

5. QA

6. Joined WhisperPower in 1998 (at that time Mastervolt Whisper Gensets BV)

10. WhisperPower is the spin - off from the Generator division of Mastervolt which was founded in 1998

11. 14 Mio EUR sales in the first 18 months

13. From 3 kVA – 25 kVA, low and high rpm

14. System approach – all installation components from one supplier

15. Various markets: marine, mobile, domestic, defence

17. Electrical: From 12 V battery based systems to high kVA 230 V/50 Hz AC systems

18. Technical installations became more and more complicated in order to meet customer need for comfort: entertainment, comfort during mooring, anchorage and navigation

20. Price/ performance /size / weight / audible noise level and “ silent time” critical

21. Interfacing of components with Bus systems

22. System design in such a way shore power can be used in an optimal way

24. More adequate service, higher quality, better infrastructure (marinas), more cost effective approach/ lower prices

25. Environmental: audible noise, emissions, exhaust gasses, soot, more efficient hull design, building materials must be durable, etc.

27. Owners want to navigate the vessel with family – preferably without crew

28. All comfort from home has to be available

29. Short and long range use

30. Systems have to work properly, silently and clean

32. Hull design, building material wood FSC approved, low emission engines, exhaust filters for generators etc.

33. Latest launch: AzimutMagellano 50 Ft (Hull design by Bill Dixon, exterior Cor de Rover)

35. We can improve the energy balance by using the generated energy in a better way

37. Hybrid Generator (5 kVA) Sine wave inverter provides AC power from 24VDC, inverter power 2kW Continuous, 4kW peak Permanent Magnet alternator integrated with fly wheel: compact and high efficient Intelligent power management system controls: variable engine speed Switch mode battery charger with 3-stage charge characteristic 1-Cylinder WhisperPower diesel engine

38. Transfer Switch Power Electronic Converter Diesel Internal Combustion Engine Permanent Magnet Generator Block diagram AC Load G Battery

40. Permanent magnet technology

41. Flywheel alternator

42. Power electronics /inverter technology

43. Microprocessor control and power management

44. Oil cooled engine

46. Lower CO2 emissions

47. Lower exhaust emissions

48. Silent mode

49. Lower noise when running

50. Shorter running time

51. Longer lifetime

52. High peak power

55. Lower kVA rating of generator batteries will provide surge power (peak shaving)

56. Variable periods of “silent navigation”

57. Battery operates vital functions: maneuvering, hydraulics etc.

58. More freedom of interior design

59. Less environmental pollution

61. Hybrid Power and Propulsion Yacht Name : YANKEE Yacht Class : J-Class Sail No : J US 2 Year : 1930 LOA : 125ftft LWL : 84ft Beam : 22ft 6in Draught : 14ft 6in Displacement : 148 tons Sail Area : 7,288 sq ft Mast Height : 153ft

62. Hybrid Power and Propulsion Early 2012 Rainbow will be launched and rigged, after which there will be an extensive training period for crew and racing crew. In June 2012 at the J class event at Falmouth and Cowes, Rainbow JH2 will be able to compete against her sister ships for the first time.

63. Hybrid Power and Propulsion

65. 2 - 3 hours of electrical – zero emission – navigation

68. E-Propulsion and power generation

69. SAE 1 interface, 550 mm dia,150mm length

70. Water cooled stator

71. 460mm diameter stator

72. Inner rotor concept

74. Hybrid Power and Propulsion Shore 30kw 1ph-3ph 50/60hz 650 Vdc Short break 30kw -3 ph 50hz No-break 30kw -3 ph 50hz

75. Cooling pump Hybrid 0,75KW -400V- 3PH Cooling pump Freeze 0,75KW -400V- 3PH Cooling pump Arco 0.75KW -400V- 3PH Hydraulic Pump 1 35KW -400V- 3PH Bilge pump 35KW -400V- 3PH Arco Compressor 2.8KW -400V- 3PH Hydraulic Pump 2 35KW -400V- 3PH Sea water pump Arco 0.75KW -400V- 3PH FIFI pump 4KW -400V- 3PH Arco compressor 2.8KW -400V- 3PH Sea water pump Freeze 0.75KW -400V- 3PH Sea water pump Hybrid 0.75KW -400V- 3PH Shore Power 30kw 50/60hz Short break 30kw 400VAC 50hz NO break 30kw 400VAC 50hz

77. No generator(s) needed during sailing

78. Over 16 hours of silent mode, no generators even when Airconis on

79. Variable speed generator starts when batteries require recharge or high loads are switched on

80. Genverter generator will adapt RPM to load pattern – low noise level at low rpm

82. Diesel- electric with battery mode

83. Optimal freedom when configuring the interior

84. Diesel (s) are used for propulsion AND power generation

86. But much smarter functionality silent mode “ hotel periods” and zero emission navigation

87. Shore power amperage not a real issue / power support / peak shaving from the battery

88. Strong reduction of wear and tear/ maintenance costs

90. Rainbow Regenerative Power 13kn

91. Load Behavior
