If you want to combine rough water comfort with passion, this very special offshorer is the right choice

Anyone who has ever travelled on the Maakermeer or Ijsselmeer and experienced the steep and short waves there can imagine how choppy the Maakermeer was on our test day with wind forces of around 5 Bft. You need a boat with good rough water qualities so that you can still enjoy travelling long distances.

And this is where our test boat, the Sacs Rebel 47, comes into play, as it not only has a deep V-hull, but also tubes filled with special foam that provide the necessary buoyancy at just the right moment when diving into the wave.

But that's not all: special offshore seats provide soft cushioning for the driver and two co-pilots. The best thing is that they can be adjusted in terms of firmness and thus adapted to the respective weight and desired level of comfort.

They definitely won us over, because with around three hours of riding time, we had no back problems and still had a lot of fun jumping over the waves.

With the sea, we sometimes thundered along at full throttle - which is over 40 knots. In the opposite direction, we were also travelling quite easily at 30 knots.
OneA special feature is the driveOutboards, sterndrives and the surface drives installed on our test boat are all possible. The power is supplied by two 550 hp Cummins diesels.

A clear characteristic of the surface drive: the tail, also known as theRooster Tailwhich the Rebel pulls behind her. In the acceleration phase, the propellers still turn quite "airily" up to around 18 knots before they gain real grip and then get the boat, which weighs over ten tonnes, moving at full speed. The faster, the higher the propellers have to be trimmed towards the surface.

It should be clear that the 1100 diesel horsepower needs to be fed properly: At cruising speeds of around 25 kn, the consumption is 4.5 l/sm and thanks to the two 750-litre tanks, an acceptable 280 nm plus 15% reserve is possible. Full-throttle pilots consume a good 5.2 l/sm, but after 243 nm both tanks are empty except for the obligatory reserve.


Fast circles can be travelled without any problems, but they are quite large. The advantage is particularly evident in the low lateral forces, with no hooking or rocking.

Slaloming is hardly possible as the hull reacts very slowly to rudder movements. To ensure that the harbour manoeuvre works, the shipyard has installed bow and stern thrusters, which provide extra safety, especially on windy days. Two electronically controlled single-lever controls, which are easy and precise to operate, also allow the Sacs Rebel 47 to be steered directly with the gears engaged in opposite directions.


AboutTwo large and easy-to-read monitors the driver can find out important information about the location or engines, for example. There is literally a whole range of round instruments for engine monitoring.

To access the diesels, all you have to do is press a button and the engine flap lifts up together with the sunbathing area. There is not a lot of room to work between the engines, but things look better at the sides. Lines and hoses are clearly laid out and the fuel can be cleanedDiesel filter with exemplary e-alarm.

Apart from a few silicone seams and gaps in the protective coating, the workmanship is impressive. The high-gloss lacquered fittings below deck are particularly elegant.


Four people in total can spend the night on board. Two in the double berth (1.62 m x 2.04 m) in the bow and two in the underfloor berth (1.54 x 2.00 m). However, there is no partition wall between the cabins. The wet room is different, it is separated from the rest by a door. In addition to a toilet and washbasin, there is also a shower. A deep-drawn edge at the toilet restricts comfort.

The perfect place to relaxtwo sunbathing areas on deck. The front has two longitudinally moulded loungers on which the crew can also relax during the journey.as in Abraham's bosom can feel. A seating area with table adjoins the double sunbed at the rear. The fully equipped wet bar is located in front of it. Above the front section is aHardtop with sunroof that lets the sun in.
