A top speed of over eighty kilometres an hour, chilled wine on board, top quality speakers for the ultimate sound experience and LED lighting which can change colour in time with the music.


The new Waterdream s-850 Speedster offers all this and more, earning it the sobriquet ‘the king of sloops’. 

This is the world’s fastest boat in its class, hand-built in the Netherlands to a unique design and with an eye for detail. The Waterdream s-850 Speedster represents unsurpassed luxury. 

The Speedster’s designers were keen to create the ultimate sound experience. They called in two of the leading experts in the field, Rockford Fosgate and Pim Temsen. The result is a system with six speakers, two sub-woofers, output of over 3000 Watts and a DIP computer to ensure that the sound is distributed evenly throughout the boat.

Bernhard van Oranje: “Although we have used the same hull design as the standard s-850, everything else about the Speedster is entirely new. Over 25 people have been involved in its design and construction. The end result demonstrates why the Dutch boatbuilding industry enjoys such a high global reputation. We are really proud to have brought Yamaha’s racing DNA onto the water with the fastest sloop ever built, combining unprecedented speed with unparalleled luxury.”

The Dutch company Waterdream has developed the Speedster based on its highly successful 850 model.


The limited edition Speedster – there will be only five – is hand-painted in the colours of the Pata Yamaha Official World Superbike Team. This distinctive shade of blue is exclusive to Yamaha racing bikes, which are made in the same factory as the Speedster’s engines.

The Speedster is undoubtedly the fastest sloop in the world. Its Yamaha 4.2 litre V6 four-stroke 300 hp speed prop engine can thrust it across the water at over 80 km/h. Automatic trim tabs virtually eliminate listing and heeling at any speed, enabling your guests to enjoy their drinks and nibbles in comfort! The Speedster even has its own onboard wine refrigerator, as well as hand-stitched leather upholstery and a top-of-the-range sound and lighting system.

Waterdream was founded by Bernhard van Oranje in 2012, since when it has established a sound reputation for high-quality aluminium boats, all hand-made to the very highest specifications and with a fine eye for detail. For example, the Speedster s-850 has a 110 cm carbon-fibre steering wheel, something that has never before been seen in a boat of this size. The sleek design of the engine compartment, with no handles or protuberances, allows it to double as a comfortable sundeck. The luxury look-and-feel is completed by the unique lighting design by Wakersdelight. The Speedster’s seating area is trimmed with BleufinLed LEDs which extend below the waterline and which can be set to change colour with the beat of the music.

Contributing ideas

Rockford Fosgate, the premium car and marine audio brand, is involved in the develop- ment of several audio packages for our boats. Rockford Fosgate do not only contribute ideas, they also determine with their German engi- neers the ideal setup.

Optimal sound

We offer a basic setup with 4 speakers with a Bluetooth streamer, a midrange package with 8 speakers and subwoofer, and an extreme package with a Digital Sound Processing (DSP) computer that ensures optimum sound distribution on the boat, 3 amps and 10 + 1 speakers. The installation is performed by Pim Tensen.



Innovative and reliable

Waterdream opts for Yamaha motors because they are among the lightest, most innovative and most importantly reliable outboard mo- tors. In addition to high torque, they provide much horsepower, reinforcing the sailing qualities and performance of the boat.

Standard and more!

The standard motor delivered with Water- dream boats is the Yamaha FT25 (25 HP High 


Thrust), but other motors can be ordered. The larger Waterdream models can be equipped with the Yamaha 300 ( 300 HP ), F200 (200 HP) or two F115 (115 HP). Starting with models F30, Yamaha outboard motors come standard-equipped with the Y-COP anti-theft system, the variable trolling system and the Yamaha LAN network system. Depending on the model, the Power Trim and Tilt system comes standard and SDS (Shift Damping System) propellers are avai- lable. The largest Yamaha outboard motors are also equipped with electronic control of throttle and shift functions (drive-by-wire). In addition to the gasoline variant, it is also pos- sible to choose an electrical power unit

Optimal and personalised service.


In partnership with Yamaha, we can provide our global customers good support on engines. With the many optional features available, we offer an optimal and personalised treatment of the customer’s order. So you can start with a 25 HP motor and later replace it with another with more horsepower depending on your needs. Yamaha also thinks along with us about what could be the best engine setup for your boat. This creates the optimal situation for personalised service to our customers.
In addition to the gasoline variant, it is also possible to choose an electrical power unit.
