An asterisk after the sail dimensions above indicates that a computer algorithm was used to determine the figure shown based on partial data (usually the I, J, E, and P). Needless to say, these data should be carefully checked. If there is no asterisk, the poster has input the data. The source for this data will be indicated on the source line at the top of the page. No matter the source, we highly recommend that all measurements be checked carefully before utilizing them. More Detail
