Product description Seldén Mast in-mast furling mast is a mainsail reefing and furling system. The furling geer has been developed from experience gained from FURLEX foresail roller-reefing, and is dimensioned for the toughest conditions. The unique design of the halyard swivel bearing distributes the load over the whole ball-race to give ...

Checking luff extrusion tension prior to stepping the mast The luff extrusion is correctly tensioned before leaving the factory, but tension can be re-checked before stepping the mast. Lay the mast horizontally, and check that the extrusion is just clear of the mast wall at its mid point. If adjustment is neccesary see points 1-5 below.

The ten- sioning screw is now freed. Twist the tack hook back towards the tensioning screw Undo the lock retaining screw and free the locking tube.
Operation & Operational hints Reefing and unreefing is accomplished with a reefing line and an outhaul, either through working at the mast, (see fig. 7.1). or by the lines for operation from the cockpit. If in-mast furling mast is to be operated from the cockpit then a reefing line in the form of an endless loop in combination with a self-tailing winch is recommended.

Fig. 7.1 Fig. 7.2 Alternative clew outhaul arrangement. When reefing from the cockpit the reefing winch must be set to ”FREE”. Use 10 mm diameter double plaited line for the endless loop. The mast kicking bracket/turning block on the mast has removable sheaves to allow a pre-spliced endless ...
Fitting and hoisting sail 1. Check that the tack and head of the sail are made as illustrated on page 10. An incorrectly made tack can cause wrinkles in the sail and make smooth furling difficult. 2. Remove the covers. Fig.
5. Hoist the mainsail whilst simultaneously ensuring that it is feeding correctly into the luff extrusion. 6. Set the halyard and cleat it with the rope stopper. The halyard tail can be stowed in the mast by feeding it through the hole just below the halyard winch. 7.
The sail The luff extrusion is asymmetrically shaped to help overcome initial resistance when starting to furl. Do not use too heavy sail cloth in the luff area. To improve sail shape when reefed and to reduce draft. ”Luff foam” may be used along the luff. The foam should not be placed closer than 50 mm (2”) from the front edge of the luff as it will then increase initail reefing resis- tance.
Running cables All in-mast furling mast extrusions have one or more cable conduits. These run uninterrupted to the mast heel even on keel stepped masts. A messenger is threaded through all empty conduits at the factory to facilitate cable drawing. A new messenger should be drawn through a conduit at the same time as a cable is drawn through.
Maintenance of the in-mast furling mast Periodic Maintenance Maintenance should be undertaken at least once a year. All bearings should be greased with GREASE (Part No. 312-501), a tube of which is delivered with the mast. Read the following instructions and fig. 13. l. When greasing bearings and gears, do not over-grease.
Removal of the in-mast furling mast gear from the mast Lay the mast horizontally on trestles. Detach the luff extrusion from the in-mast furling mast gear by slackening the tension and undoing the togg- le. (See page 4, ”Luff extrusion adjustment”). Remove the in-mast furling mast gear from the mast by undoing the eight holding bolts and taking it away from the mast.

Important points to remember before setting sail The sail must always be rolled to the starboard side of the luff extrusion. Turn the reefi ng winch clock- wise. The leech should always be kept fairly taught when reefi ng or furling. Use the topping lift! ...
