The system is fully electric with a minimum energy consumption. No need for a running genset. Humphree Fin Stabilizers are optimised for low water resistance, high efficiency and manufactured in advanced materials with unique characteristics. With the ability to rotate 360° at anchor – anchor walking is no longer a problem. The unique innovative custom-ready fin design will perfectly fit most hulls.

Combining the Humphree fin system with our interceptors and you have a full stabilization system for roll, pitch and yaw motions. For best control and lowest fuel burn.

Many waterjet boats experience course keeping problems. This is due to the missing underwater lateral area that helps the vessel to keep its course. An added lateral area is most efficient when installed in the very aft of the hull. Having a wing profile fin gives a corrective force on yaw with minimum resistance. Humphree has developed a series of fixed fins that can be bolted to the hull. The bolts have been tested and verified to break off and keep the hull intact to limit the damage to the boat in the event of collision or grounding.


  • Sub-cavitating stabilising fins (below 40 knots)
  • Several sizes available, HFF400 and HFF650
  • Base-ventilated stabilising fins (above 40 knots) HFF500
  • Several sizes available, HVFF300 and HVFF500

Our interceptors make the difference between enjoyment and seasickness; between low and high fuel consumption and between bad and excellent visibility at the helm.


X-Series for 25-60 feet boats

The X-Series is available in five standard sizes. Intended mainly for boats 25-60 feet. They deliver the same reliability and superior performance as all larger Humphree interceptors. The X-Series features the same control system, ultra-fast servo actuators and control panel. For superior control of dynamic hull motions they all have an interceptorblade with a powerful 50mm (2”) stroke. The X300 and X450 are also an excellent choice for high performance RIBs.



H-Series characterizes a customizable interceptor and are available from 350 – 1500 mm in width. No matter how the hull of your boat has been designed there is always a solution for our interceptors to fit the hull. And also be fit under your water jet, a perfect fit at the shine or make it follow the radius of the propeller tunnels,



This interceptor line with an asymmetric placed servo unit can be used when it has to fit under a water jet or if preferred area of the transom is limited. Also when the inner structure on the inside of the transom does not allow for a centre placed servo. The HA-interceptor can be custom shaped for a perfect fit and comes in sizes 500 – 1100mm.



The HE-Series interceptors are designed for heavy duty use. With their powerful 75mm stroke length they will add 50% more lift force than the standard 50mm interceptors. The HE-interceptor comes in sizes 750 – 1500mm and can be custom shaped for a perfect fit.



the HL-Series are designed and built for the large and heavy planing vessels. With a mechanical high performing structure the HLS-interceptors blade has a powerful 110mm stroke length. The HLS interceptor is available from 800mm to 1500mm width.


The HCS-5 system

The HCS-5 combines exceptional mechanical quality with electronic control including motion sensors and world class brushless servo motors to provide instant and exact response to the hull dynamics. Adding the fine-tuned boat control options Automatic Trim, Automatic List, Coordinated Turn or Active Ride Control will result in optimum comfort and performance regardless if the captain is a seasoned expert or a less experienced operator. All the units are connected with watertight cables with the servo motors positioned protected inside the hull. HCS-5 can easily be upgraded with more functions, interceptors and fins.



The HCU500-series control units consists of advanced sensors, calculating algorithms and works on 11 – 32 VDC. The control unit handles the system functions, controls the servo motors and powers the system. In a network with electrical fins, these are separately powered by 24VDC electricity.



CP502 is our new and advanced control panel – very easy to use – with a large colour display which is sunlight readable and therefore also suitable for outdoor installation, such as the flybridge. The control panel can change between day- and night mode and user selectable colour themes. CP502 is NMEA2000 certified which makes many installations easier. For service and support the control panel has an integrated Wi-Fi access point that enables remote access via your Internet connected device such as a mobile phone or computer.
