bow
Front of a vessel
Cleat
Metal fitting on which a rope can be fastened
gunwale
Upper edge of vessel's side (generally pronounced
... [Show More] "gunnel")
Hull
Body of a vessel
port
Left side of a vessel
propeller
Rotates and powers a boat forward or backward
starboard
right side of a vessel
stern
Rear of a vessel
beam
Maximum width of a vessel
draft
Depth of water needed to float a vessel
Freeboard
Distance from water to lowest point of the boat where water could come on board
keel
Main centerline (backbone) of a vessel or the extension of hull that increases stability in the water
Displacement Hull
move through the water by pushing the water aside and are designed to cut through the water with very little propulsion
If you lower a boat into the water, some of the water moves out of the way to adjust for the boat. If you could weigh that displaced water, you would find it equals the weight of the boat. That weight is
the boat's displacement.
Boats with _________ hulls are limited to slower speeds.
displacement
A round-bottomed hull shape acts as a ___________________. Most large cruisers and most sailboats have ___________, allowing them to travel more smoothly through the water.
displacement hulls
Two types of Hulls
displacement and planing
personal watercraft
A small vessel that uses an inboard jet drive as its primary source of propulsion, and is designed to be operated by a person or persons sitting, standing, or kneeling on the vessel rather than inside the vessel
planing hulls are
designed to rise up and glide on top of the water when enough power is supplied. These boats may operate like displacement hulls when at rest or at slow speeds but climb toward the surface of the water as they move faster.
Boats with ______________can skim along at high speed, riding almost on top of the water rather than pushing it aside.
planing hulls
__________ and vee-bottomed hull shapes act as planing hulls.
Flat-bottomed
Most small power-driven vessels, including ___________ have planing hulls, allowing them to travel more rapidly across the water.
personal watercraft (PWC), and some small sailboats
Displacement Mode:
A planing hull, when operated at very slow speeds, will cut through the water like a displacement hull.
Plowing Mode:
As speed increases, a planing hull will have a raised bow, reducing the operator's vision and throwing a very large wake. Avoid maintaining a speed that puts your boat in this mode
Planing Mode:
enough power is applied so that the hull glides on top of the water. Different boats reach planing mode at different speeds.
flat bottomed hull
Has a shallow draft, which is good for fishing in small lakes and rivers but Rides roughly in choppy waters.
Deep-Vee Hull
Gives a smoother ride than a flat-bottomed hull in rough water but Takes more power to move at the same speed as flat-bottomed hulls. May roll or bank in sharp turns.
Round-Bottomed Hull
Moves easily through the water even at slow speeds but has a tendency to roll unless it has a deep keel or stabilizers.
Multi-Hull
Has greater stability because of its wide beam but needs a large area when turning.
Length overall is measured from the
tip of the bow in a straight line to the stern of the vessel.
___________ are not included in the length measurement.
Bowsprits; rudders; outboard motors and motor brackets; handles; and other fittings, attachments, and extensions
length overall
Length of the hull excluding any attachments [Show Less]
