HYDRAULIC POWER PACKS AND LINEAR DRIVES
FOR AUTOPILOTS
INTRODUCTION
L.S power packs and linear drives for autopilots are perfectly adapted to the requirements of
different applications, such as pleasure boating, workboats, professional or amateur fishing,
competition and its accompaniment.
They are easy to install, state of the art machine finished and made to resist a marine
environment.
You can easily select the best suited system for your boat within the most comprehensive range
available on the market with a guarantee of efficiency, reliability and security.
Our systems carry a 2 year warranty and are CE approved. They are fully compatible with all brands
of autopilots on the market today.
DESCRIPTION OF HYDRAULIC POWER PACKS AND
LINEAR DRIVES FOR AUTOPILOTS
As a general rule, the basic set up of a hydraulic system for autopilot consists of:
• 1 hydraulic cylinder,
• 1 hydraulic power pack,
• Fittings and tubing to connect the cylinder to the power pack.
Other elements will be added to this basic set up in function of the configuration of the boat steering
system – hydraulic steering, wire ropes, cables, etc.
Cylinder
The cylinder is the dictating element in the selection of a system. It gives the pushing power to the
steering system in function of its effective area and the pressure it receives from the power pack. To
select the cylinder, follow the method given in paragraph "Selection of the System".
Hydraulic Power Pack
Power packs are always composed of a reversible or non reversible electrical motor in 12 or 24 volts
DC, or 220/240 V single-phased or three-phase, coupled to a reversible or non reversible axial piston
pump or gear pump, with adjustable or fixed flow rate.
Receiving orders from the electronics, the power pack will suck or force back the oil in the circuit. The
speed of correction is determined in function of the pump flow rate in litres per minute.
Our systems are fitted with lock valves which prevent cylinder movements once the boat is on the
desired course until a new course correction is required.
They are also fitted with pressure relief systems to protect the circuit against abnormal pressure
increases.
Tubing
Tubing is designed for hydraulic oil transfer under pressure. Tubing diameter is selected in function of
the power pack flow rate.

HYDRAULIC POWER PACKS AND LINEAR DRIVES
FOR AUTOPILOTS
WORKING PRINCIPLE
When the boat moves away from the displayed course, the autopilot electronic computer sends
current to the motor terminals or to the power pack electrovalve. Then, the cylinder will be supplied
with oil and set in motion. As soon as the boat is back on the displayed course, the computer stops
supplying the power pack and the cylinder stops moving.

FOR AUTOPILOTS
SELECTION OF THE SYSTEM
For boats equipped with a hydraulic steering, it will be necessary to determine:
- The volume of the steering cylinder (take the biggest volume in case of a single rod cylinder)
- Available voltage on board (12 VDC, 24 VDC, etc.)
For planing or semi-planing hulls, the power pack will be selected in function of its flow rate so that the steering cylinder will run its
complete stroke within 10 to 12 seconds.
For displacement hulls, the power pack flow rate must enable the steering cylinder to run its complete stroke within 15 to 17 seconds.
Examples :
RSpeed boat, planing hull with a 239 cc cylinder – Available voltage 12 VDC
s (1 minute)
x 0.239 litre (239 cc) = 1.195 litre / minute
12 seconds (required time)
The flow rate of the required power pack will be 1.19 litre / minute, therefore we will select a reversible power
pack with adjustable flow rate type RV2 (12 V) – page 5
RFishing or work boat, displacement hull with a 2,307 cc cylinder – Available voltage 24 VDC
(1 minute)
x 2.307 litres (2,307 cc) = 9.228 litres / minute
15 seconds (required time)
The flow rate of the required power pack will be around 9 litres / minute, therefore we will select a power pack type
HF 1.5 – 9 (24 V) – page 6
For boats equipped with a mechanical steering (wire ropes, cables, rack and pinion), it will be necessary to
determine:
- The rudder(s) torque
- The available voltage on board (12 VDC, 24 VDC, etc.)
Torque Calculation:
For boats fitted with a rudder with speed not exceeding 25 knots, the torque (C) of the rudder or rudders will be
calculated according to the formula and correction coefficients below:
C = S x [ (0.4 Lg) – Lc ] x V² x K
C = Torque in kpm
S = Total surface of rudder (H x Lg) in sq. m
H = Height of rudder in m (metre)
Lg = Width of rudder in m (metre)
Lc = Compensation width in m (metre)
V = Maximum speed of the boat in knots
K = Coefficient according to total angle of rudder
- Port to starboard 70° K = 15.89
- Port to starboard 80° K = 17.80
- Port to starboard 90° K = 19.52
Corrections in function of the type of boat:
- For sailing-boats C x 0.5
- For boats fitted with several rudders (catamarans, trimarans, monohulls), multiply the calculated torque
result by the number of rudders fitted on the boat.
Examples:
H = 1.2 m Speed under sail = 12 knots
Lg = 0.7 m Speed with motor = 8 knots
2
Lc = 0.18 S = 1.2 x 0.7 = 0.84 m
2
Torque under sail = (0.84 x [(0.4 x 0.7) – 0.18] x 12 x 15.89) x 0.5 = 96.11 kpm
2
Torque with motor = 0.84 x [(0.4 x 0.7) – 0.18] x 8 x 15.89 = 85.42 kpm
Selection of the linear drive :
Torque not exceeding 50 kpm Linear drive type 32 ST 16 page 8
Torque not exceeding 100 kpm Linear drive type 40 ST 16 page 8
Torque not exceeding 200 kpm Linear drive type 50 ST 20 page 8
In the above example, the calculated torque is 96.11 kpm. Therefore the correct selection will be a linear drive type 40 ST 16.
Note: for sailing boats with a modern hull and balanced rudder, the selection can be made in function of the boat length
as below:
Length not exceeding 33 feet Linear drive type 32 ST 16* page 8
Length not exceeding 44 feet Linear drive type 40 ST 16* page 8
Length not exceeding 60 feet Linear drive type 50 ST 20* page 8

ENERGY SAVING DEVICE "ECOPILOT"
LOT"
The "Ecopilot" energy saving device was designed to meet the demand for electrical energy saving on sailing-boats. Power
reserve on board is often very limited, however it is essential for the operation of an autopilot system.
The "Ecopilot" acts on the electro-valve which engages the autopilot. The power consumption of this electro-valve represents a
major part of the total autopilot consumption.
Its action consists of letting through - during a short moment – the necessary current for the electro-valve to switch on. Then
the current is significantly reduced but still sufficient to maintain the electro-valve in position.
Thanks to this system, the daily consumption of the electro-valve is reduced in average from 30Ah to 5Ah.
