Fins

Our fins are optimised for low water resistance, high efficiency and manufactured in advanced materials with unique characteristics.

All Speed Fin

Humphree stabilising fins brings state of the art technology with fast acting brushless electric servo units. Powered by 24 V DC it gives you possibility to have full comfort without the need of genset running.

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

Features & benefits

– 24V DC – clean operation without hydraulics, and no genset required!

– 360° rotation – combats anchor walk
The 360° rotation allows Humphree to rotate the fins 180° and gently pull the anchor when anchored at the bow. This minimise the so called anchor walk and will keep the bow against the wind to a noticeable extent reducing waves coming from the side.

– Flange mount
The unique fin flange mount design minimises the damages in case of grounding and makes installation of fins very easy and fast

– All Speed Stabilisation
Full stabilisation at anchor and at full speed!

– Integrated Interceptors for total motion control (Pitch & Roll)
The combination of Interceptors and fins makes the difference, total motion control.

– Compact Size & low weight
Sturdy and compact with unbeatably low weight. A depth of only 310mm from outside hull. Humphree All Speed Fins can easily be retrofit installed where other options are too big.

Stabilising fin

The new electric fin stabilising system from Humphree brings a cost and power effective stabilising system to the marine market.

 

To control Roll and Pitch motions on board the vessel improves the ride and comfort for the crew and passengers. For better damping efficiency of a Fin Ride Control system is a proven design for underway stabilisation.

Features & benefits

– 24V DC
Powered directly from the power bank in the vessel there is no need for complicated installations with hydraulic pipes.

– Brushless electric motors
The electric motors have a minimum requirement of service.

– Designed for 24/7 operating time
No matter how many hours you have of operation per year, the Humphree pitch fins will keep your vessel stabilised.

– Classified installation
The installation can be class aproved.

Electric Rudder

The Humphree 24V DC electric rudders are used for superb course stability minimizing yaw movements. The rudders are operated in manual or during auto pilot mode. Effective integration with waterjets minimizes thrust losses when steering, saving fuel and increasing vessel speed. The use of electric rudders also provides less wear and tear on the waterjet steering systems.

Features & benefits

– Immediate steering response

– Improved vessel speed

– Less fuel consumption (up to 10%)

– Superb course keeping

– Improved maneuverability

– 24 V DC electric powered

– Easy integration with waterjet steering systems

– Emergency backup steering

– Easy to install

– Several rudder sizes are available

Fixed Fin

Many waterjet boats experience course keeping problems. This is due to the missing under water 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.

Features & benefits

– 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
