Abstract
A mast footing having a tensioning device for the leading edge with the components which provide for a reduction of force being attached to the mast footing such that they may be detached. When the sail has been correctly trimmed, i.e., with the leading edge tensioned, the device is removed from the arrangement. Then, only a hook-shaped device of short length is attached between a loop at the neck of the sail and a hook at the mast footing, which device preferably has a constant length or, at most, may be fine-tuned within a range of a few centimeters.
