Abstract
A roller reefing boom system includes a mast track arrangement, a sail and a rig which permit the transfer of extremely high mainsheet tensions via the leech to the mast even with a minimum luff diameter without the luff unintentionally being pulled out of the mast slot. The system guarantees troublefree furling of the mainsail with a minimum of space.
