bow - .....ANSWER ...✔✔ front of a boat
stern - .....ANSWER ...✔✔ Rear of a vessel
starboard - .....ANSWER ...✔✔ right side of a vessel
port - .....ANSWER ...✔✔ Left side of a vessel
hull - .....ANSWER ...✔✔ the frame or body of ship
gunwale - .....ANSWER ...✔✔ the upper edge of the
side of a boat or ship

cleat - .....ANSWER ...✔✔ Metal fitting on which a
rope can be fastened
propeller - .....ANSWER ...✔✔ Rotates and powers a
boat forward or backward
beam - .....ANSWER ...✔✔ Maximum width of a
vessel
freeboard - .....ANSWER ...✔✔ Distance from water
to lowest point of the boat where water could come on
board
draft - .....ANSWER ...✔✔ Depth of water needed to
float a vessel
keel - .....ANSWER ...✔✔ Main centerline (backbone)
of a vessel or the extension of hull that increases
stability in the water
Displacement Hull - .....ANSWER ...✔✔ Boats with
these 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 these are limited to slower speeds.
A round-bottomed hull shape acts like this. Most large
cruisers and most sailboats have these, allowing them to
travel more smoothly through the water.
Planing Hulls - .....ANSWER ...✔✔ Boats 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 can skim along at high speed, riding almost on top
of the water rather than pushing it aside.
Flat-bottomed and vee-bottomed hull shapes. Most small
power-driven vessels, including personal watercraft
(PWC), and some small sailboats have planing hulls,
allowing them to travel more rapidly across the water.

personal watercraft - .....ANSWER ...✔✔ 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 Hull Speeds - .....ANSWER ...✔✔
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 plowing mode.
Planing Mode: Your boat is in planing mode when
enough power is applied so that the hull glides on top of
the water. Different boats reach planing mode at
different speeds
Flat Bottom Hull - .....ANSWER ...✔✔ Advantages:
This planing hull has a shallow draft, which is good for
fishing in small lakes and rivers.
Disadvantages: Rides roughly in choppy waters.
