Waterdream S-550

Our 5.5 meter sloep with superb handling, wide body, stability & a handmade beauty

Aren’t you going on holiday this year? Take a vacation this summer on a new S-550. This 5.5 meter long aluminium sloop from the Waterdream S-line is meant for the demanding water sportsman who is looking for a high quality sloop and at the same time modest in size.

The Waterdream S-550 is developed in collaboration with Yamaha.

This spacious sloep combines the charm of the old lifeboats with the excitement of a modern speedboat. Agile and stable, the S-550 can be used for all-year boating, and even wakeboarding. The boat is powered by Yamaha, starting at 10 hp and up to 60 hp. The boat is also self-bailing.

High quality sloop

The Waterdream S-550 is intended for demanding water sports enthusiasts who are looking for a high quality sloop that is modest in size.


The sailing characteristics of the Waterdream S-550 are equivalent to the larger models and a slow sailing version can be chosen which is powered by a Yamaha F20BEL outboard engine or a fast sailing version which is powered by a Yamaha F50HETL outboard engine. Because of its dimensions and weight, the Waterdream S-550 is also perfectly trailerable behind a middle class passenger car.
