Steering controls power when sailing downwind. Bear away in gusts and luff up in the lulls to keep the boat level.
在顺⻛航⾏时,掌舵可调节动⼒。遇阵⻛时,顺⻛偏转;⻛⼒减弱时,迎⻛偏转,保 持船体⽔平。
Conventional (Symmetric) and Asymmetric Spinnakers
传统球帆(对称球帆)和不对称球帆
The conventional spinnaker was developed to gain better speed downwind. With the heeling forces greatly reduced when going downwind, it was possible to fly this specialist sail while running and gain considerable speed without excessive heeling. Originally only flown on runs, sailors soon developed the skill of sailing slightly higher to gain speed by flying the spinnaker on a broad reach.
As sailors in the development classes were at the forefront of these changes it was no surprise to see more specialist sails being created by the Australian 18-foot class. Races were won by gybing conventional spinnakers downwind and sailing much greater distances (Course Made Good (CMG)) at a significant speed advantage (Velocity Made Good (VMG)) in these planing hulls.
