| 摘要 |
The present invention relates to improvements introduced for a sail for boats, wherein said improvements are based on the inclusion of a second cloth (15) in the sail having a smaller width than the main cloth thereof which ensures effective sail wind behaviour on reefing conditions, as the intrados surface and extrados surface thereof remain intact during said operation, in addition to the inclusion of a movable flap (16) at the end opposite the mast (5) of at least one of the sail cloths (1; 15). |
