SAIL SYSTEM WITH ADJUSTABLE SAIL AREA ABSTRACT OF THE DISCLOSURE A sail and mast assembly for a wind driven craft, such as a tailboard, includes a main sail section and one or more removable sail sections attachable to the foot of the main sail section, thereby to provide a sail with adjustable sail area to suit varying wind conditions. The assembly also includes an adjustable-height mast, to which the sail is operatively attached, whereby the mast height can be changed, as removable sail sections are added or removed, to maintain a desired proportion between the mast height and the length of the leading edge or luff of the sail. In a first embodiment, the mast height is adjustable by a telescoping mechanism, while in a second embodiment, the mast height is changed by attaching or removing mast segments to the bottom of the mast.
