US Sailing Level 1 LSR ExamCenter of Lateral Resistance (CLR) - Answer -the focal point of all the forces resisting slipping sideways
through the water (keel and rudder)
Center of Effort - Answer -theoretical focal point of the force generated by the wind acting on the sail(s)
- main and jib
Drag - Answer -slowing force resulting from the friction of a boat moving through water
when a boat is sailing upwind, it slips to - Answer -leeward
centerboard's primary responsibility - Answer -resistance to side-slipping
rudder's primary function - Answer -steering
weather helm - Answer -occurs when sailing upwind in strong or puffy wind-force of the mainsail
overpowers the jib- boat turns windward and the rudder is harder to control. correction: ease main, hike
to windward, flatten mainsail, or pull up centerboard (25%)
lee helm - Answer -The boat's tendency to turn away from the wind in light wind - too little force in the
mainsail and too much weight to windward. correction: flatten boat (move crew weight leeward), tiller
to leeward, make mainsail fuller/deeper and put daggerboard all the way down.
, why flatter is better upwind - Answer -vertical centerboard/daggerboard functions best at preventing
sideways slipping, most direct course toward windward destination
heel in light air upwind - Answer -little heel allows for better steering and optimal sail shape to avoid
luffing
side-to-side position downwind - Answer -daggerboard up partway, heel to windward to reduce friction;
skipper on windward rail and crew adjusting to maintain consistent windward heel
fore and aft position upwind - Answer -too far forward: pearl in waves. too far aft: stern sinks/displaces
more water. skipper aft of mainsheet&crew shoulder to shoulder. light wind: slightly forward better.
heavy wind/big waves: farther aft to keep bow up.
fore and aft position downwind - Answer -higher wind: shift weight back to keep bow out of water, then
move forward to sail upwind.
hiking - Answer -anticipate changes and adjust weight placement beforehand. flat boat decreases
sideways slippage for more efficient windward travel. straight legged hiking = center of gravity farthest
possible to windward
close hauled sailing - Answer -position defined as closest to the wind
high or low close hauled course - Answer -high: pointing closer to the wind, maybe edging No-go zone.
depletes good wind flow and is slow. low: almost close reach position. increases wind power & faster
but sacrifice pointing toward wind.
the groove - Answer -course between the high and low side of close hauled. best speed and highest
pointing windward angle. telltales streaming, correct heel, neutral helm.
ease-hike-trim method - Answer -in a puff: ease sail slightly, hike boat flat, trim sails back in to regain
power once in control.
