A velocity prediction program can translate sail performance and hull characteristics into a polar diagram, depicting boat speed for various windspeeds at each point of sail. Displacement sailboats exhibit a change in what course has the best velocity made good (VMG), depending on windspeed. For the example given, the sailboat achieves best ...

Three dogs attacked their owner at a San Diego park Friday, killing the man and injuring another person, according to authorities and the Humane Society.
Although there are differences in the sailing aspects of the two designs, their measurements are very close, with a waterline length of 18 ft (5.49 m) and an average beam of 6 to 8 feet (1.83 to 2.44 m), not including the wings. With wings the maximum beam is 14 feet for the "International 18" and 18 feet for Open 18's sailed at Sydney Flying ...
