Alado Roller Furling & Reefing since 1992
In terms of engineering concepts, Alado is one of the simplest and easiest systems to use.
To understand completely how it works, it is best to set aside any expectations (un-learn what you know for a minute) that you may have as to how a separate Jib Halyard is necessary to lift the sail or how a winch is necessary to set the tension of the sail.
The Top Assembly with two sheaves is supported by the interlocking foils which in turn are supported by the drum, which is supported by the stay clamp resting on the connection fitting at the end of the wire. The system freely turns independently of any swivels.
The sail is lifted by the mechanical action of a 1:1 lift using the uphaul line of the external halyard. For every foot lifted an equal foot of line is required.
The head of the sail should stop just a few inches below the sheaves to allow full tensioning ability. If not, satisfactory tension may not occur. TIP: Installing the System then measuring the "luff" distance before you cut or order a sail will ensure no " size surprises" when you install the sail.
Once sail tension is achieved, secure the "downhaul" line of the external halyard.
Secure the line(s) by tying the line at the drum or by adding a rope clutch at the drum using a shackle.
It is not recommended to drill any holes in the drum as this will void the warranty.
The use of a high-quality low stretch rope for the external halyard will mitigate any accidental loosening of the sail.
For racers, changes to the sail and tension are made by the Bowman. Using both luff feeds will assist in a speedy sail change.
