CORRECT ANSWERS|| 2024 LATEST UPDATE||

Center 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




drag - ANSWER increased friction of the boat moving through the water; unequal
pressure from water flowing past rudder.


roll tack - ANSWER quickens pace at which bow passes through no-go zone and
improves acceleration once boat has tacked


jibing downwind - ANSWER faster is better. put daggerboard all the way down
prior to jibe. slightly more tension on vang.


s-turn jibe - ANSWER safety jibe in heavy wind. counteracts rounding up by
steering back down slightly into the jibe without jibing again.

, roll jibing - ANSWER faster, more efficient jibe that minimizes use of rudder and is
most effective in light/medium air.


avoiding capsize to windward - ANSWER usually occurs in moderate/heavy wind
on a run. boom vang tight to reduce twist (depowers sail), centerboard lower than
in light air, if boat rolls head up or trim in slightly. can be caused by mainsheet too
far out, vang too loose, centerboard too far up, oversteering, waves/wind/crew
placement.


sculling - ANSWER Moving the tiller back and forth quickly to move the boat
ahead, usually when docking


shortening sail - ANSWER in more control with less sail area exposed to wind. 1)
lowering jib (will have to pull tiller windward to avoid weather helm), reefing
(lowering sail partially and securing lower portion to boom), lowering mainsail
(will have to push tiller leeward to avoid lee helm with bow rotating away from
wind).


spring lines - ANSWER Lines that lead fore and aft to prevent forward and aft
motion of the vessel when docked. aft (or after) bow spring extends from bow to
aft quarter; forward quarter spring extends from stern to forward quarter.


anchoring - ANSWER 1) sail on a reach 3-6 boatlengths downwind of target
location, when directly downwind of target, head up into wind. 2)lower anchor &
pay out anchor line as you drift back. 3) firmly cleat rode, check anchor is holding,
lower mainsail
