>> Halyard / Mast : 50% reduced load With the locking device, the halyard load is transferred to the lock, reducing nearly by half

this compression and allowing lighter mast.

>> Reduction of the boat heel/windage widely fitted on raceboats, the lock reduces the boat heel and windage, even in cruising.

 >> Reliable mechanisms 

 >> Luff constantly tight (constant tension) : wind pressure increases are not absorbed by the halyard elasticity.

- Gennaker or code zero

- Staysail fitted on textile forestay

- Staysail fitted on furler with flying wire forestay

>> Options : Fitted-in sensors : «upwards stop» and «locked»,

Various terminals available With toggle directly fitted-in (swivel)

It can be fixed onto one head attachment with an articulated device (toggle, latching, Unibal ball or others). The halyard can then run down inside or outside the mast

• Fixed locking device and mobile pin 

• Locking swivel with fixed pin / removable swivel 

in this case, the external body of the lock is directly laminated (composite mast) or riveted/bolted onto the front head of the mast. The luff reaches an optimum length. The halyard runs down directly inside the mast.
