The new WhisperPower system certainly seems to be the Egg of Columbus. On the E6, our new 65 ft model, it is running perfectly: Seakeeper on and air conditioning on, generator off, no problem. I’ve been out on the sea with westerly winds of force 6: with a cruising speed of 15 knots, no problem at all, in fact you could even describe it as extremely comfortable. Furthermore, with this sort of wind and the waves, plus a top speed of 22 knots out on the North Sea was still without problems. The WhisperPower system continued to function perfectly under all of these circumstances." Anton van den Bos, Director of Neptune Marine Shipbuilding, builder of Elling Yachts.
“During the design and build of the innovative DutchCatTwelve - DutchCat’s very first catamaran concept - I received a lot of helpful advice from WhisperPower. With the 48V power system they have supplied, you are able to sail for a long period of time whilst also enjoying all of the comfort on board, without the need to charge the system. Excellent company with excellent products. For more information on this unique concept visit www.dutchcat.nl." Jan van Eck, Managing Director Dutchcat.

"For the DAKAR Rally, I opt for the best material - with me, quality comes first. That is why I chose WhisperPower as the power supply for my 18 meter motor yacht. Perfect products with super service!" Hans Stacey, famous Dutch rally driver.
Auke van der Werff - Volharding Stavoren Shipyard
“WhisperPower is an undisputed leading brand. We are more than happy to use their generators as a power source on board - we are particularly taken by the new Piccolo: small, lightweight, powerful and with a very acceptable noise level.” Auke van de Werff, Director of Volharding Stavoren Shipyard, builder of Sturier and Dutchman yachts.
Hans Webbink - Steeler Yachts
"Since 2014 we have been equipping our yachts with complete WhisperPower packages. On our smaller yachts a combi (charger / inverter) and a large battery bank is usually sufficient. With our larger yachts there is an increasing demand for comfort (and silent power). Our customers expect that all the comforts from home are also available on board. With these large yachts, the installation of induction hobs, air conditioning, fan assisted ovens and even Quookers are becoming not the exception but the rule. In addition to onboard comfort, our customers also expect the power supply to be just "like home". A large number of our boats are now equipped with the the WhisperPower ‘New School’ systems." CEO Steeler Yachts
"We are very impressed by WhisperPower’s product range, plus the service is faultless. We deliver our deck-saloon sail yachts to customers around the world fully satisfied that we are guaranteed accurate technical support." Torsten Schmidt Sirius-Werft GmbH, Plön, Germany
Paul Eytjes - Eleggtricks
“At long last there is a high power capacity inverter system available that is able to provide a complete 230 V or 120 V onboard installation with power. An important innovation in this product is that you do not experience instability in the DC system which would usually cause visible fluctuations in the power line. An important additional advantage is that if the system has been well calculated, there is no need for it to be (re)connected to other AC sources. The WhisperPower System is the ultimate solution for both smaller and larger vessels. For owners who want to cleverly handle their onboard power and for those it just want it work, hassle-free.” Paul Eytjes, Owner / Director Eleggtricks, Engineering and Contracting, the Netherlands.
Dorus Wajer - Wajer Yachts
“The reason we have chosen WhisperPower installations, including the battery systems, is because their systems are robust and reliable. This is exactly what we need for our Wajer Yachts, all of which are delivered to customers with an onboard service contract. In this respect, as far as WhisperPower is concerned, we never have to worry.“ Dorus Wajer from Wajer Yachts BV.
Wies Hokwerda, De Boarnstream
"At the request of a Swiss customer, last year we installed the so-called WhisperPower 'New School’ system on our 14m Elegance. The concept impressed us so much that we put the system on the option list and have already sold and installed a number of systems. On our Elegance 1300 a system has been installed with a large battery bank connected to solar panels and an additional alternator fitted on the main engine which together ensure that the battery bank is always full. A 7kW inverter supplies all 230V consumers on board. The installed generator is only called in to action when the boat is anchored for a longer period of time. And for charging whilst in port, low shore power voltage is not a problem.” Wies Hokwerda, Director De Boarnstream, Friesland.
"On our latest model, our flagship Northline 50, in order to achieve comfort and silent time, we have opted for a WhisperPower Hybrid system. The 8 Lithium Ion batteries are charged by the extra alternators whilst the boat is sailing. This means that when anchored, the 640Ah "power tank" is full and therefore we can just carry on doing what we want and need to without the generator running. The 14kW inverter effortlessly supplies the 230V consumers, including a Quooker hot water system. If there are long periods of high power consumption, we have set the generator to start automatically. Further still, the client can clearly monitor the exact power consumption on the 10” screen which can also be used to set the shore power voltage - a top system which the customer is also more than happy with!” Sipko van der Sluis, Owner Yachtbouw Zevenhuizen / North-Line Yachts.
"I was the first user of the WhisperPower ‘New School’ system. It was really a pilot project. The idea that without needing to start the generator you could still be able to cook and run the air conditioning at night in the sleeping area only using the batteries really appealed to me and it seems to be working really well! On my boat there are 2 WhisperPower alternators fitted on the main engine and these run when we are cruising making sure that the big battery bank is full for when we are at anchor. I can almost always get through the night on “silent power”. If I have used a lot of silent power during an evening, before I go to bed I start the WhisperPower Generator (which is also extremely quiet) for an hour and the 2 x 150A battery chargers make sure the battery bank is full again. In the case of our boat, a 7kW 230V inverter is sufficient to supply the 230V consumers. A great system and I can recommend it to anyone. It turns out that in practice, we run the generator very little.” Mr van Rhijn, owner MY Pacific Pearl.
“It was in 2016 when we came across the phenomenon ‘New School’. A customer with a Van Den Hoven 21m motor yacht had initially chosen a traditional system. When the power demand was high, the combi’s were not proving to be the ideal mix. The generator was having to run almost all of the time when there was a demand for large power supply because the 2 x 3.5 kW inverters were having difficulty with prolonged periods of high use. The system has since been modified, the Combi's have been replaced with 2x 150A DC PowerCube chargers which are powered either by shore power or Generator and a 14kW inverter that feeds the consumers directly from the batteries. Whilst cruising, the 1650Ah battery bank is fully charged up so that on arrival in port we have sufficint supply for a long period of silent power. A top system! The choice for our latest model, the Hoven Executive 1850, was therefore not at all difficult - a WhisperPower New School system!”
