BOAT ED Course Exam Questions with Verified
Solutions
Personal watercraft
small vessel using inboard jet drive as primary propulsion source; operated by sitting, standing,
or kneeling on the boat rather than from inside of it; less than 16 feet long; PWC
Parts of a PWC
safety lanyard, steering control, bow, engine, intake grate, intake, drive shaft, impeller, steering
nozzle, stern
Fuel selector switch
switch on PWC that can help avoid getting stranded without fuel; on position used while
underway; off position used when engine off; reserve position used if you run out of fuel while
underway
Rudder
steering device, usually a vertical blade attached to a post at or near the stern of the boat
Tiller
lever used to turn a rudder to steer a boat
Transom
vertical surface at the back of the hull
Halyards
lines or ropes used to raise and lower the sails
,Sheets
lines or ropes used to control the angle of the sails to the wind
Swamp
to fill with water
Capsize
turn on the side or completely over
Bilge
interior of the hull below the floorboard; lowest part of a vessel's interior where the sides of the
vessel curve in to form the bottom
Coupler
the part of the trailer that attaches to the ball hitch on a towing vehicle
Bunks
wooden supports on which the vessel rests while on the trailer
Bow
front of vessel
Stern
rear of vessel
Starboard
right of vessel
,Port
left of vessel
Hull
body of vessel
Gunwale
upper edge of vessel's side
Cleat
metal fitting to attach rope
Propeller
rotates to power boat forward and backward
Beam
maximum width of vesel
Freeboard
distance from water to lowest point of boat where water could come aboard
Draft
depth of water needed to float vessel
Keel
backbone of vessel or extension of hull that increases stability
, Displacement hull
boat moves through water by pushing it aside; designed to cut through water with little
propulsion; amount of water displaced by boat equals weight of boat; limited to lower speeds;
round-bottom hull shape; large cruisers and sailboats
Planning hull
boat rises and glides on top of water when enough power supplied; skim along at high speeds;
flat-bottom and vee-bottom hull shape
Displacement mode
when a planning hull operates like a displacement hull at low speeds
Plowing mode
when the boat has a raised bow so operator's vision is reduced and a large wake is created; speed
at which this occurs should be avoided
Planning mode
when enough power is supplied for the boat to glide on top of the water
Flat-bottom hull
advantage - planning hull with shallow draft; good for fishing in small lakes and rivers
disadvantage - has a rough ride in choppy water
Deep vee-bottom hull
