The Reckmann SF is a combination of a turning padeye and a hydraulic stay tensioner. The furler can tension and furl inner foresails. The self-aligning deck suspension allows a flush deck installation and avoids bending loads on the extended piston. The furler is equipped with a strong hydraulic brake and a removable stay connector with a quick release pin for fast sail changes.
In keeping with our staysail furling systems, we offer a range of swivels. In addition to offering various materials (titanium and aluminium) we also provide various connection options.
This deck connection is based on a spherical segment in a low-friction bearing seat. Owing to the type of construction used, this bearing is significantly smaller. However, the sphere only allows for a maximum deflection angle of +/-10° in all directions. This means that the furling system has to be installed in an inclined deck structure.
The Reckmann load holding valve block combines several functions:
The integrated check valve keeps the hose depressurised, even with attached stay loads, therefore preventing damage caused by a burst hydraulic hose. The adjustable pressure relief valve, which is also integrated, loosens the stay adjuster in the event of an overload and thus prevents the furling system from being damaged. An optional pressure sensor allows for real-time monitoring of the internal cylinder pressure and therefore the attached stay load.
