摘要

The water craft (1) has a line control roller (30) for controlling main lines/sheets (22-1, 22-2), directional lines/sheets (22-3, 22-4) and a front line/sheet (22-5), where the main lines connect a main aerial sail (20) e.g. wing, to a floating body (10). The roller has a rotary axle (33) on which a line storage coil (31-3) and other line storage coils are mounted. The coils are respectively associated with the main, directional and front lines, and integrally connected to the axle. Each coil associated with the directional line is freely rotated around the axle on a non-zero angular course.
