摘要
The deck of the vessel has several frames with a vertical mast, which carries a wind pressure surface (11). Each wind surface consists of horizontally or vertically displaceable steel sheets. The sheets may be rolled up on drums, and are guide on both sides by steel rods. All wind surfaces may be adjusted from a central point. Horizontal slide surfaces (10) and the steel rods have rollers to guide to wind surfaces.
