Sailing : 

Sailing By: Andrew Roberson

What is this “Sailing”!? : 

What is this “Sailing”!? Sailing is the art of controlling a boat with large (usually fabric) foils called sails. To traverse or travel on (a body of water) To travel on water propelled by wind

History now. : 

History now. Throughout history sailing has been instrumental in the development of civilization. The earliest representation of a ship under sail appears on a painted disc found in Kuwait dating to the late 5th millennium BC.Advances in sailing technology from the Middle Ages onward enabled Arab, Chinese, Indian and European explorers to make longer voyages into regions with extreme weather and climatic conditions. There were improvements in sails, masts and rigging; navigation equipment improved. From the 15th century onwards, European ships went further north, stayed longer on the Grand Banks and in the Gulf of St. Lawrence, and eventually began to explore the Pacific Northwest and the Western Arctic. Sailing has contributed to many great explorations in the world.

Basics parts ja? : 

Basics parts ja? ~As far as parts go for A inexperienced sailor there is only 9 simple parts you need to remember. ~Each part has a specific job, all necessary.

Seems too easy… : 

Seems too easy… It is, those are only the basic parts, being that from a horizontal parallel view To the right is a very simple picture that shows the 4 ‘sides’ of a vessel. Fore= Front Stern= Back A more detailed picture for quick readers. Still basic IMO.

What if I hits someones?!?!? : 

What if I hits someones?!?!? We got that cover. THE RIGHTS OF WAY!!! The rights of way are very complicated but worth knowing. Remember the rule of thumb just like driving, right has the right of way. Wind

Why does it not flip over? : 

Why does it not flip over? The correct term is capsize, fool. Like so. CLR (center or lateral resistance), aka the mast in a ideal situation. FR (fore resistance), aka the resistance/pressure given off by the forward part of the boat AR (Aft resistance), aka the resistance given off by the aft (or back) of the boat Heeling.

How does a boat move?? : 

How does a boat move?? ~This uses one of the terms stated before, CLR. First off, the wind puts pressure on the sail of the boat making it tip (or heel) this is going to be called SP, or sail pressure. ~The centerboard (or keel on some boats) is moved by this underwater, it has resistance put back on the sail (CR centerboard resistance). ~Adding the two together against each other they even out (if you add in weight put out by the people steering the boat)

My mind is spinning. Do I need to know all of this? How much should I care about each thing? : 

My mind is spinning. Do I need to know all of this? How much should I care about each thing? To help keep your priorities straight, and to avoid confusion, I placed the points you really needed to know the most in the beginning. The physics is just that, physics.

Racing : 

Racing Racing, is the hardest part about sailing. There is a start, the most crucial part. There is usually a triangular course marked by 3 buoys. There is usually 3 to 6 laps, depending on distance and wind speed. If your not first you’re either the first loser or sleeping on the floor for the rest of your life.

Conclusion : 

Conclusion Sailing is a great pastime that has entranced the world since the beginning of time and is complicated at first but once studied and practiced it can provide much pleasure, from bonding time with the family to a career.
