Waterworld 4.0 i 7.5 i 10.0 i 20.0 i electric inboard motor 4 - 20 kW 48V

• Review Watersport Tv online Epco Ongering Antaris Seventy5 with Waterworld 15 kW:
  If you look at the boat from the inside, you will immediately notice that the floor is completely flat and that there is no engine box. A separate table has been placed in that place and the rest of the cockpit in the middle is empty. This is possible because an electric motor has been placed under the floor here. Electric drives are lower than diesels and that even applies to the 15kW strong Waterworld electric motor. Just like the tender itself, the entire electric drive system is Made in Friesland.

  Integrated
  The 39 kWh battery pack is very advanced and consists of three parts with 2112 lithium iron phosphate cells. This pack has a management system like in modern electric cars. The nice thing is that the engine, management and batteries are integrated and that everything communicates with each other. If a cell fails, the entire system adapts immediately.
  On the clear Raymarine display you can read all the important data. Even if you have been able to charge at a restaurant in between, you can see that directly on your display. In addition to engine and consumption data, the display shows map data or other Raymarine options such as echo image of the water under the boat if desired.
  On the test day the weather was tough Frisian. A strong wind force six lashed the Frisian water around the shipyard in Woudsend. It is immediately noticeable that the drive with the 15kW Waterworld electric motor has more than enough power to give the strong wind a chance.
  The integrated display makes us happy, because when you sail very quietly (for example 4 kilometers per hour) you only use 350 Watts.
  The display then shows that you could sail for 4 days at this speed without interruption and have a range of 385 kilometers. That greatly increases the sailing area of ​​this power tender.
  The energy consumption is extremely low. At a speed of 8 kilometers per hour we consume 1.6 kW and we can keep that up for more than 24 hours with the largest 39 kWh lithium battery pack. At this speed you get a range of 192 kilometers on 1 charge.
  If you sail 10 kilometers per hour, you can see from the waves around the boat that you have reached hull speed. Then we use 4.3 kW, you can even keep that up for more than 9 hours and you have a range of almost 100 kilometers. You can go even faster, about 14 kilometers per hour. But who wants that?

  Advantages
• The WaterWorld motors are brushless asynchronous electric motors, which are powered by a 48 Volt battery pack and directly drive the propeller shaft.
• Quiet and clean. The WaterWorld engines operate in complete silence. The silent engine drives the axle without transmissions. Enjoy the peace and quiet that this gives and the clean air!
• Affordable. A complete WaterWorld system is no more expensive than the old diesel. The modern production, easy installation without water cooling and the limited maintenance ensure that. The Waterworld engine can replace the diesel without much extra cost.
• Or consider a more affordable pod motor.
• Reliable. The proven Dutch technology and easy installation ensure that you can rely on the WaterWorld drive. That gives peace of mind.
• Sustainable is also: Made in Holland. The WaterWorld systems are made in our own country by the professionals of Water World Electronics. And therefore not in countries with low wages far away. And that means: no transport of products halfway around the world.
• Easy to install with adjustable engine mounts that fit most existing foundations
• Engine and electronics in one, equipped with air cooling. Water cooling is unnecessary. Super efficient – ​​Affordable and longer sailing. The WaterWorld engine is so efficient that it produces little heat. Therefore, no water cooling is required! This makes installation easier , there is no chance of blockages and maintenance is minimal . Once on the water, another major advantage is apparent: you can sail longer with your boat.
  
  
• Replacing a diesel engine? A new diesel inboard engine is no longer an option, not even in terms of price!
  • 30 hp diesel: over 100 kilograms, 80 dB (loud conversation), 25% efficiency, annual oil change, winterization, environmental pollution.
    vs
    10 kW Waterworld: 76 kilograms, 45 dB (inaudible on the water), more than 85% efficiency, no maintenance, environmentally friendly.
    
    
• Very silent engines.
  
  
• Modern technology and design. When you lift the hatch you see the sleekly designed engine and electronics. But in daily use it is especially the modern touch screen colour monitor and the design of the throttles that stand out. In addition to the standard supplied display, it is also possible to see all information on your Raymarine screen or on your iPad via the special WaterWorld app (iOS integration).
  
  
• Suitable for intensive and professional use. The WaterWorld systems are also used in charter ships, tour boats and work boats. The robust engines, which can also continuously deliver maximum power, make this possible. The same applies to the WaterWorld batteries, which can handle up to 3,000 cycles while retaining almost all energy.
  
• A complete system with a 3-year warranty: that gives peace of mind. The WaterWorld components are integrated into one system. Via a CAN data connection, the engine, controller, batteries, display and throttle work together seamlessly. This way, you always have the necessary information on your display about the condition of the engine and batteries and the remaining range.
  And when using the WaterWorld batteries in the system, you get a 3-year warranty on the entire system.
  
  
• Sailing boats can regenerate: so you can charge your battery while sailing. With Waterworld you can regenerate continuously.
  In a full electric situation with a sailing boat, you should think of 500 W att to 2 kW, depending on the speed from 10 kilometers per hour; in a hybrid setup (rigid connection to the propeller shaft) you can reach 8 kW. This option is available for the 10 kW and 20 Kw engine: WaterWorld Regeneration package for hybrid or regeneration for sailing boats 695,-.

  • Example: the wooden sailing ship Boeier de Otter is equipped with the WaterWorld 15kW (see photo). The 'Otter' slowly glides through the doorway of the boathouse in Heeg, except for the sound of some splashing propeller water it is completely silent. That was what skipper-owner Peter van Heijst was mainly concerned with: peace and quiet on board, even on the engine. So that you can always enjoy your sailing trip, even when there is no wind or the wind right on the nose in narrow waters forces you to use engine hours. In the past you would then have been in the noise of a pounding diesel. But the aspect of greener sailing also appealed to Peter, despite the relatively high investment costs that this entails.
    The power of a combustion engine cannot be converted one-on-one to an electric motor, the differences are too great for that. For example, an electric motor delivers a much higher torque at a low speed and 'a few more teeth' also differs in the amount of extra energy consumption. Liters per hour suddenly become kilowatts per hour, simply a different calculation. The old diesel engine delivered more than 22 hp, more than enough to get the Otter up to hull speed.
    The electric motor also does a 'quiet' job at a cruising speed of five knots, consuming 1.5 kilowatt-hours. (Source: Stichting Stamboek Ronde en Platbodemjachten). Quiet and clean.
• A traditional 14-metre / 12-ton Bolpraam has also been converted to electric with a WaterWorld 15 kW electric motor.
  
  
• For heavier boats the ePropulsion I-10, I-20, I40, H-100 Electric inboard motor 10-100 kW 96 V is available.

• Example AdmiralsTender 28: With 16 kilometers per hour this exceeds the hull speed and that is a step faster than you would expect. The electric motor is combined with three Torqeedo lithium batteries of 5 kW. Good for a full day of sailing. With the fast charger the batteries can be charged in a few hours.
  
  
  

Hybrid .
The WaterWorld systems can also function perfectly in a hybrid setup. Both parallel hybrid, with a diesel and WaterWorld both driving the propeller shaft. And also as a series hybrid, where the combustion engine of a generator converts the mechanical energy into electrical current, to store in batteries and to feed the Waterworld engine.
Two parallel versions: 4 kW Hybrid version 4.0i and 10 kW Hybrid version 10.0i.

For parallel hybrid requires customization and we need the following information for a proposal:

• Make and type of boat and water length and displacement.
• Wishes regarding speed, sailing time and range.
• Is recharging by sailing on diesel desirable?
• Engine make and type.
• Maximum diesel engine speed.
• Speed ​​at 1500 rpm with diesel.
• Make and type of reversing gear (and reversing gear reduction).
• Available space around the reversing gear.
  Space above the reversing gear or further back around the propeller shaft is necessary. Space in front of the diesel engine is not usable.
• Maximum applicable diameter for a gear pulley immediately after the reversing clutch. Common sizes are 135 or 155 mm.
• How is the propeller shaft mounted and (with regard to force distribution) in what position? Please also provide photos of this.
• Space around the propeller shaft/flange reversing coupling with regard to diameter.
• Gear ratio.
• Corner of the setup.
• Propeller shaft and bearing arrangement (support bearing, python drive present).
• Propeller shaft water lubrication; water scoop / auxiliary pump during electric sailing?
• Type of screw. This is related to determining performance speed/torque.
• What is known about the propeller and the speeds at certain revolutions?
• Engine compartment ventilation inlet and outlet openings.
• Available space for batteries.
  
  
• A WaterWorld motor can be mounted above or next to the propeller shaft on a bracket, which is then fitted with a pulley.
  A separate engine bracket that stands on its own foundation above or next to the propeller shaft is also an option.
  The propeller shaft is fitted with a pulley with a toothed belt ensuring transmission.
  Since the electric motor is mounted on vibration dampers and the toothed belt is tensioned (by means of a tension roller), the alignment of the electric motor must be correctable.
• Pulleyset WaterWorld consisting of 2 toothed belt pulleys and Taperlock clamping bush for propeller shaft and a toothed belt (HTD 30 - to be measured after mounting). 455,-
• Currently only a standard ready-made bracket design is available for the Vetus 42 HP.
  For custom-made bracket construction, a welding or construction company or yard will have to be used to weld a frame.
  First it must be determined how many kW electric motor is needed and what diameter pulleys, then the dimensions of the frame can be determined and the legs to mount on the plane or foundation (trusses). Usually this is about 1 day of work + materials (estimated 150,-) such as (stainless steel) angle, bolts, threaded rod for a clamping possibility, welding electrode etc.
  Marinaut can supply the necessary drawings for this.
  
• Installation time hybrid entirely dependent on engine mounting, available space etc. 4 - 6 days.
• Exclusive WaterWorld Service Activities: - guidance installation in preliminary phase - commissioning on location - actual hours and travel expenses on post-calculation estimated 8 hours at 85 per hour in VAT. In principle, the customer can purchase the commissioning directly from Waterworld, preferably a business customer. It is important that the installer is present during the commissioning. Sometimes it is necessary for him to do some fine-tuning/adjustments/alignment at that time.
• Waterworld checks the installation and then the adjustment of the regeneration (lower and upper values), checks the safety devices and limit switches for Morse control + test run, checks under load, heat development in the motor, controller and wiring, etc.
  Additional costs of Hybrid integration with current engine; based on: Can Open; delivery of safety kit (including sensor on current throttle/reversing clutch); adjustment / test run of steering on existing setup (including torque/nominal load) 2,195,-
