Product details

The ultimate solution for effortless manoeuvring and maximum stability at low speeds.

When manoeuvring in harbours or other confined areas, precise speed control is essential.

With the propeller stopped, boats without an effective rudder system lose much of their steering capability. As a result, many boats struggle to maintain their intended direction without repeatedly engaging and disengaging the engine. However, this inevitably increases speed, making precise manoeuvring even more difficult.

With the Course-Keeper, the boat’s natural deceleration can be used to full advantage. This allows calm, controlled manoeuvring at minimal speed, guiding the boat accurately into position.

Thanks to its additional rudder effect, the Course-Keeper makes reversing particularly easy. It enables precise stern control and allows you to bring the boat smoothly alongside the dock with confidence.

Low-speed handling presents a challenge for many boats, as hull shapes are typically optimised for higher speeds.

In addition, environmental regulations often require reduced-speed navigation in certain areas. At lower speeds, course stability frequently suffers — the boat may begin to roll, requiring constant steering corrections.

The Course-Keeper significantly improves directional stability. Its effective rudder action reduces the need for continual steering adjustments, resulting in smoother, more controlled navigation.

Available in four sizes:

  • Type 1 – for boats up to 5 m
  • Type 2 – for boats up to 6.8 m
  • Type 3 – for boats up to 8.5 m
  • Type 4 – for boats up to 10 m

No drilling is required for installation. The COURSE-KEEPER is simply bolted to the cavitation plate.
For use with Volvo Penta DP drives (series 280/290), the VP (Volvo Penta) version must be used.

The Coursekeeper does essentially what he is supposed to do. However, the price for 2 aluminum plates, which unfortunately are not very stable, is 2 thread bars and the joints with springs much too high. The material value is well under 20 euros. The 2 Aluplatten are completely bent even at the first lateral contact with reason and have me my propeller destroyed. The construction is far too unstable, especially at this price.

flop
Installation wasn't as easy as claimed. My 250 hp OB planer is somewhat more stable at slow speeds. BUT, it won't plane anymore. The coursekeeper won't fold up; the spring that supposedly adjusts it isn't adjustable at all for the average consumer. And even if it were, it creates a tremendous wake, and the boat gets stuck in a semi-planing position. I'm taking it apart again. It was an expensive mistake.

With our boat (6m sport boat, 135 HP Z-drive) has no remarkable effect, no stabilization set at slow speed. Will dismantle the part again. Service and delivery by SVB were outstanding.
