The SPARCRAFT manual stoway masts work with a tried and tested worm drive reefing system. The perfect lead of the reefing control allows partial or totally furl the main sail from the cockpit in a reliable way. In addition Sparcraft can offer a hydraulic or electric drive system to make reefing even easier.

The SPARCRAFT manual stoway masts exclusively use worm drive systems. This system is the only way to guarantee a perfect furling operation without jamming, and can be operated by one person (two-hand control).

The sections range from 4.9kg/ml to 15.9kg/ml, and are a perfect alternative to the standard sparcraft sections (see also the custom chapter for large boats). It is possible to offer all our customers ¨C yards, professionals or private customers, either a furling or a traditional mast with the same mast step reference and the same running and standing rigging.

The groove opening is off centre in order to improve the reefing operation when using the manual version.
