Implications On Sailing Speeds
In sailboat racing, and especially in speed sailing, apparent wind is a vital factor, when determining the points of sail a sail-boat can effectively travel in. A vessel traveling at increasing speed relative to the prevailing wind will encounter the wind driving the sail at a decreasing angle and increasing velocity. Eventually, the increased drag and diminished degree of efficiency of a sail at extremely low angles will cause a loss of accelerating force. This constitutes the main limitation to the speed of wind-driven vessels and vehicles.
Windsurfers and certain types of boats are able to sail faster than the true wind. These include fast multihulls and some planing monohulls. Ice-sailors and land-sailors also usually fall into this category, because of their relatively low amount of drag or friction.

Famous quotes containing the words implications, sailing and/or speeds:
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (18951985)
“To sunny waters some
By fatal instinct fly; where on the pool
They sportive wheel, or, sailing down the stream,
Are snatched immediate by the quick-eyed trout
Or darting salmon.”
—James Thomson (17001748)
“An honest tale speeds best being plainly told.”
—William Shakespeare (15641616)
