Deck 2014: Safety

1. A If the thrust on a sail becomes excessive when close-hauled, it is likely to capsize the vessel rather than drive it.
2. 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.
3. C A properly trimmed sail should have laminar flow on the windward side and turbulent flow on the leeward side.
4. D Adjusting the angle of attack on a mainsail is accomplished by adjusting the outhaul or the vang, if fitted.
