Small deployment = Large lift

Model testing results with equivalent lift:

Interceptor drag is 25% less than for Trim tab

The centre of lift is moved aft by 35% with interceptor (Provides larger lifting moment)

Humphree Interceptor system

Humphree Interceptor system

By adding lift to the stern of the vessel.

The vessel will change trim angle and

bring the bow down.

Possible achievements on hull performance

• Increased top speed

• Increased cruising speed at same rpm

• Increased range

• Improved fuel consumption

• Less environmental impact

• Improved stability and comfort

• Improved sea keeping

• Faster acceleration

• Wider speed range

Control systems

Humphree Boat Control Systems

• Automatic Trim Control – Automatic longitudinal trim control (pitch)

• Automatic List Control – Automatic list control (roll)

• Coordinated Turn Control – Automatic heel control in turns

• Active Ride Control – Active vessel stabilization, pitch and roll damping

• Interceptor Steering Assistance – Automatic steering assistance using interceptors on

water jet powered vessels

Humphree Functions

Automatic Trim Control

Longitudinal vessel trim is automatically adjusted to provide

optimum running trim for highest speed, lowest fuel consumption or

best possible running attitude.

Automatic Trim Control

The system automatically adjusts the Interceptor blades according to the vessel speed

Humphree Functions

Automatic Trim Control - Summary

Longitudinal vessel trim is automatically adjusted to provide

optimum running trim for highest speed, lowest fuel

consumption or best possible attitude.

• Always perfect Trim angle

• Better visibility

• Faster accelerations

• Reduces fuel consumption

• Increased top speed

Humphree Functions

Automatic List Control

With Auto List the captain simply sets the target angle and

the system will automatically adjust to the preferred boat

list (most often zero degrees).

Humphree Functions

Automatic List Control

The system automatically adjusts the Interceptor blades to reduce list

Auto List Control

Automatic List Control - Summary

- Corrects list for uneven load

- Corrects list in side wind condition

- Improved comfort

- Flexible loading conditions

(people, load, fuel and water etc.)

Humphree Functions

Coordinated Turn Control

This function controls heel characteristics during

turns for best comfort and safety. Additionally the

turning circle can be significantly reduced.

Humphree Functions

Coordinated Turn Control- Lift force gives the vessel support during the turn, to achieve that “true turn” angle

- Interceptor lift contributes to the turning radius

Hydrodynamic lift force

Humphree Functions

Coordinated Turn Control

Allows the vessel to heel with true

turn angle in 28 knots.
