us sailing level 1 Questions AND Correct Answers EXAM
backstay - ✔✔ standing rigging that runs from top of mast to transom
pulls the top of the mast back and is used to control the shape and leech of the main thereby adding
or reducing power
controls the shape of the jib through headstays/ jibluff
reduces mainsail draft by bending middle of mast
ease the backstay to increase sag in the jib luff making it have more power and fuller
tighten the backstay to reduce sag and make jib flatter
batten - ✔✔ stiffeners on the leech
beam reach - ✔✔ sailing across wind
boom vang - ✔✔ As the mainsail gets closer to the boat's centerline, and more mainsheet tension is
pulled on, the effect is similar to what other sail control?
boom vang - ✔✔ prevents the boom from rising
boom vang is too loose. - ✔✔ Which of the following factors can cause a capsize-to-windward when
sailing on a run?
capsizing - ✔✔ get in from back and pick up someone by arm pits
center of effort - ✔✔ theoretical focal point of the force generated by the wind acting on the sail(s)
center of lateral resistence - ✔✔ focal point of all the forces resisting slipping sideways through the
water (rudder and centerboard)
cirrus clouds - ✔✔ wispy, thin, usually mean good weather but could indicate a change in weather is
on the way
, cleats - ✔✔ where running rigging is tied
clew - ✔✔ corner of the sail by the stern of the boat, corner between the leech and the foot
close hauled - ✔✔ boat is about 45 degrees from the wind direction- sails are trimmed in close and
the boom is positioned somewhere between the centerline and the leeward side of the hull
close reach - ✔✔ 60-75 degrees from wind direction- sails are let out on the verge of luffing
cold/heat emergency - ✔✔ cold:hypothermia, moved to a dry, warm environment
heat: removed to a cooler environment, medical attention should be provided in extreme cases
cummulus clouds - ✔✔ indicator of good weather, large, white and fluffy
cumulonimbus clouds - ✔✔ thunderheads, usually accompanied by severe conditions, including
heavy rain and lightening
cunningham - ✔✔ stretches the luff
impacts the location of the draft
current - ✔✔ horizontal
dacron line/polyprobaline - ✔✔ best for towing and anchoring
decrease power in the sail - ✔✔ Increasing the Cunningham/downhaul tension will have what
effect?
downwind sailing - ✔✔ sailing in the direction to which the wind is blowing- includes broad reaching
and running
draft - ✔✔ depth and location of the curvature in the sail
