The Black Box snuffer features a light and robust oval-shaped mouth fitted to a mesh sock. The mesh fabric has been specifically developed for the snuffer allowing for ventilation when the sail is stowed away. Black Box snuffers come in a range of lengths from 7 – 30.5m and it is recommended to choose a length just shorter than the actual luff length. The product comes ‘ready-to-sail’ with all components needed to install and use.
