Line = Rope

It is not a rope: it is a line. The origin of this term is still a mystery. Some boaters are very particular and if you ask them to help you with your ropes will act like they do not know what you are talking about. Annoying? Yes. You have been warned!

Bow and Stern = Front and Back

The front of the boat is called the bow. The rear is the stern. If someone asks you to “throw me the bowline,” you should toss him the rope at the front of the boat.

Galley = Kitchen

Any cooking area is called galley. Some believe that mariners of old cooked meals on a “gallery” of heated stones, and that “galley” evolved from poor English over the centuries.

Fender = Bumper

The rubber tube hanging off the sides of a boat to protect them from docks and other boats is called a fender. As with ropes, calling these “bumpers” can invite haughtiness, so remember—there are no bumpers on boats.

Port and Starboard = Left and Right

Port is left and starboard is right. To create a universal distinction between left and right, sailors have adopted the terms port and starboard to indicate the left and right sides of the boat from the perspective of the captain (looking forward). This can prevent confusion, for example, when two boats are approaching one another and the captain on the radio says, “please move to the starboard.” There’s no confusion about whose left and whose right is being addressed.

Stateroom = Bedroom

Boats do not have bedrooms. They have staterooms. This is thought to originate from the days when only officers or important people “of state” or status had private rooms on a ship.

Not to be completely confused with "berths" ..V Berth, and aft berth, are the most common.

Helm = Steering wheel

Helm is the term that refers to the area from which the boat is steered and otherwise commanded. The term comes from an older English word that means “rudder.”

Knots per hour = Miles per hour

Knots are the way boat speed is often measured — more so on larger crafts than on speed or ski boats. Knots measure nautical miles per hour (1.151 MPH). 



Cleat Hitch

This knot secures boats to the cleat when docked. It is easy to get wrong. As part of the family of hitch knots this one is a little trickier. Take a full turn around the base of a clear and then a figure of eight around the first cleat horn, and then the next. At the last turn pass the rope underneath itself before pulling tight.

This knot secures boats to the cleat when docked.
- agh!
WHY WHY WHY??? Can I KNOT tie this KNOT?? (pun intended)
And a little sailing history, which I discovered accidentally while browsing through old sailing pictures, about Albert Einstein. 
Albert was an avid Sailor, albeit from all accounts - not a good one- he used his sailing time to comtemplate away from others and was quite often rescued when lost or run aground.
But he loved his sailing time and never gave it up, despite his Dr's suggestion that he do so- 
Here is an exerpt from John Vigor's writings on the subject:
"Caution: Genius Aboard"
by John Vigor

Albert Einstein was a cruising sailor - relatively speaking, of course - and in his boat, as in physics, he sailed joyously close to the wind. 

Sailing was a passion for Albert Einstein, the lovable, spaniel-eyed genius with the wild white hair that floated in the wind. He learned to sail on the Zürichsee, in 
Switzerland in 1896 when he was an 18 year-old student, and continued sailing until ill health forced him to give it up more than 50 years later, long after he had become the world's most famous physicist.
Einstein sailed as he lived his life absentmindedly. He was a dreamy yet instinctive kind of sailor, bemused and delighted by his sport and pastime. His was a true passion, one undiluted by caution and unburdened by technical knowledge. His mast fell down regularly. He often had to be towed home. He almost drowned himself and had to be rescued by a motorboat, yet he refused to carry an outboard motor himself. He despised machines, declaring that he'd rather drown than permit a motor on his beloved sailboat.

The sailboat in question, one of many he owned or borrowed, was a battered 17-foot day sailor called Tinef - meaning worthless or of no intrinsic value. He sailed her extensively in New England, though it is difficult to classify, in conventional terms, the type of sailing he did.
He never strayed too far from shore. He cer­tainly didn't race. He had no desire to pit 
Tinef against any other boat. "The natural counter­play of wind and water delighted him most," said friend and sailing partner Dr. Gustav Bucky. "He wasn't a conventional gunkholer." The natural conclusion, therefore, is that Einstein was a cruising sailor. Of sorts. Relatively speaking, of course.
But sailing did not kill Einstein, 
Albert Einstein died of a ruptured abdominal aortic aneurysm. Taken to the University Medical Center at Princeton, he refused treatment, arguing that he wanted to end his life "elegantly." His death occurred on April 18, 1955.
It just proves my point- sail while you can, and love it. You may not be an expert but your passion will carry you through. Just get behind that wheel at the helm and pull those lines and sleep in a stateroom and poo in a head. 
Do it all. and Savor it- like Einstein.
