The
PROFURL motorised systems may be fitted over the existing forestay
in most cases, either with or without a turnbuckle.
The special bottom fitting allows customising installation as
per customer's expectation: raised from deck for easy anchoring
and no chafe of sail's foot on the lifeline, or low to deck
for maximum luff length. The solid custom made female-female
lower toggle and clevis pins are delivered standard with the
system. |

In
case of failure of the power supply, the PROFURL motorised systems
include a handle socket (handle supplied) located at the rear
of the housing allowing instant manual operation.
The system being irreversible, the handle may be released during
manual operation with no danger to have the system driven by
the wind in the reefed sail.

By
removing the bottom drum mechanism of a PROFURL manual system
(model 42 or 52 manufactured later than 1987), and replacing
by the corresponding gear motor, converting from manual to a
motorised system is extremely simple.
Luff extrusions may require length adjustment in some cases.

 In electric
(E) version, the system is delivered pre-wired in factory
with 2 x 5 meter (15' 6") of wire, that are to be connected
onto the relay box (supplied standard). The housing is sealed
in factory and tested for watertightness.
The systems are available in 12 or 24 Volts DC. The feeding
lines are generally the same ones being used for the electric
anchor windlass.
The 1000 W electric version averages power consumption as little
as the one of a 25 W bulb lamp during 1 hour, generally making
additional batteries unnecessary.
The hydraulic
(H) version may be connected to the most usual hydraulic
packs, with a corresponding calibration on the outputs (100
Bars for models 42, 140 Bars for models 52).
In hydraulic version, the system requires 2 feeding hoses finished
by female 7/16" JIC.
