It works like this. The wind is split by the leading edge of the sail (the mast, headstay, or luff). It is split into two turbulent streams, one on each side of the sail. One stream has slightly less force on the sail so the sail begins to move in that direction. As the flow stabilizes over that side, the wind moves faster on that side than on the turbulent side. This creates lift like an airplane wing. So the wind is actually pulling the sail, not pushing it.
Lift on the sail causes the boat to heel (lean over). Some of the lifting force is counterbalanced by the keel underwater keeping the boat upright. The remainder of the force pushes the boat downwind. However, the flat keel underwater prevents the boat from sliding downwind, with the result that the boat is forced forward.
I recommend you read this book for your next version:

Understanding Weatherfax - for an attempted (and failed) circumnavigation
Sail Power
Kon Tiki
Shogun
Art of the Sailor
Business Adventures
Metamorphoses (by Ovid, not Kafka)
Guns, Germs, Steel
Curious Incident of the Dog in the Night Time - this book had so many rave reviews. it has a tremendous hook and style for the first 50 pages, but overall I thought it was terrible
Cryptonomicon -- fantastic
Simulacra and simulation -- started, but I need to start over. this is not an easy read...
Predictably Irrational -- another book with great reviews, but reading this book was not time well spent. the author just summarizes psychology experiments with pages of dumbed down explanations and tedious anecdotes
The Alliance -- read this on my last day at my old job, a good reminder on the social contract between you and your employer and how it should be mutually beneficial, lots of boring filler though
Triple your reading speed -- I wanted to take a speed reading course when I was in elementary school, but my dad thought it was a waste of time. I think I really missed out on something, but late is better than never.
Siddhartha -- rereading of one of my favorite books of all time
The Alchemist -- rereading of one of my favorite books of all time
Jazz (by Leveaux)
The Jazz Piano Book
Mastering the Piano
Big Blue Book of bicycle maintenance
Probability (by Pitman) -- its embarassing statistics/probability isn't a required course in many programs
Elements of Statistical Learning
Advanced Analytics with Spark -- feels like this book was published only 80% done
Optimization Models (by Calafiore and El Ghaoui) -- going to finish this is 2016
Functional Programming with Scala -- going to finish this is 2016
Linux Programming Interface -- going to finish this is 2016
Finished 18 books cover to cover in 2015, 6 of which were textbooks/academic texts. Currently have 7 in progress, 2 of which are piano workbooks and 3 are textbooks.
Goal for 2016 is 30 books cover to cover, at least 8 textbooks/academic texts.
