With regard to aerodynamic lift, which statement is TRUE? |
A) Adjusting the angle of attack on a mainsail is accomplished by adjusting the outhaul or the vang, if fitted. |
B) When a sail is trimmed too tight, turbulence will break out on the windward side of the sail and cause a telltale there to flutter. |
C) If the thrust on a sail becomes excessive when close-hauled, it is likely to capsize the vessel rather than drive it. |
