Rudders and centerboards always have swiveling tips so the dinghy can be landed. Rudders often are arranged so the tiller folds against the rudder to make a compact package.

Note that the rudder shows a slight kink to the leading edge right at the top. This may be done to increase rudder chord where the rudderstock needs to be the thickest.

Attached to the stern is the rudder, which is controlled by the helm-tiller or a steering wheel. The rudder is turned to starboard (right) or port (left) to steer the boat.

Appendage:
A rudder, keel, centerboard, or skeg.
Apron:
A strengthening timber behind the lower part of the stem and above the foremost end of the keel in a wooden vessel.
In order for the rudder to be able to properly steer the boat, it must be moving through the water. The speed necessary for control is known as steerage way.
Stem
The forward edge of the bow. On a wooden boat the stem is a single timber.
sails, hull and rudder
Let's get basic. This is the first of a few short features on sailing for beginners. All terms will be defined assuming you are a complete newcomer to the sport.
HELM: The wheel or tiller controlling a rudder or outboard motor; the place from which you steer a small boat.
HELMSPERSON: The person who steers the boat.
BALANCED RUDDER A rudder with its axis between the forward and after edge. BALK A piece of timber from 4" to 10" square. BALLAST Any weight carried solely for the purpose of making the vessel more seaworthy.
ketch -- two masted sailboat that has an after mast forward of the rudder
knot -- a nautical mile (equivalent to 1.15 miles or 1.852km).
Kick-up describes a rudder or centerboard that rotates back and up when an obstacle is encountered. Useful when a boat is to be beached.
Lapper A foresail which extends back of and overlapping the mast, such as a 110% genoa jib.
It looks like a fish's fin extending below the boat, and the boat usually has a rudder mounted some distance aft, often on an additional keel-like extension called a skeg.
Finger Pier - A small pier that projects from a larger pier.
Scull - moving the rudder back and forth in an attempt to move the boat forward
sculling oar -- a large oar used for propelling a boat by moving from side to side; also used for an emergency rudder ...
The mizzen mast is generally stepped forward of the rudder post (aft of the rudderpost on a yawl) and the mizzen mast is generally larger than a yawl's mizzen.

Scuppers: - holes through the ship sides which drain water at deck level over the side.
Damage to a vessel rudder, or rudder-adjoining parts are considered as structural damage.
Ketch-Two-masted boats, the after mast shorter, but with a ketch the after mast is forward of the rudder post
Kevels.. -Two crooked pieces of timber, whose lower ends rest
in a step, or foot, nailed to the ship's sides; the head branches out ...
tillerA bar connected to the rudder and used to steer the boat. tiller handle outboardA small, outboard motor that uses a handle fitted with engine controls to steer instead of a steering wheel.
Compare to current tiller A stick or bar connected to the top of the rudder and used to steer the boat by moving the rudder toe-rail A low rail, often slotted, along the side of the boat topgallant The mast above the topmast, its sails, ...
Before ships had rudders on their centerline, they were steered by use of a specialized oar. This oar was held by a cocksman located towards the stern (back) of the ship.
A rudder is an underwater fin that moves to help with steering.
A tiller is a stick used to steer the boat from the cockpit.

When moving astern, with the engine in reverse, be aware that the rudder will tend to counteract your steering with the engine.
TILLER - A bar or handle for turning a boat's rudder or an outboard motor.
TOPSIDES - The sides of a vessel between the waterline and the deck; sometimes referring to onto or above the deck.
TRANSOM - The stern cross-section of a square-sterned boat.
Tiller - A bar or handle for turning a boats rudder or an outboard motor.
Toe-rail - A low rail, often slotted, along the side of the boat. Slots allow drainage and the attachment of blocks.
An inboard engine operates according to a "fixed screw": Turning a rudder or rudders diverts the thrust developed by the propeller(s), which in turn turns the boat. An outboard or I/O powered boat operates without a rudder.
Yawl - like the ketch only the mizzen mast is located aft of the rudder post. The standard joke is "a Yawl is just a southern ketch." Remember you heard it here first.

PAYMENT

If the speed is great enough, these hydrodynamic forces can overpower the correcting forces of the rudder. Vessel operators are expected to be familiar with these effects and to reduce their speed sufficiently to maintain positive rudder control.
A rocking motion between bow and stern. Mostly wave induced.
Yaw (Around z). This is what the rudder is supposed to do. Rudder corrections for course keeping illustrate that wind and waves can cause yawing motions.
Ship Geometry ...
A metal bar or wooden handle attached to the top of the rudder to steer a yacht. If, for example, the helmsman wants to steer to starboard, he/she pushes the tiller to port.
