| Polr Charts I am not sure of any online links, however the second edition of High Performance Sailing by Julian Bethwaite has either recently been released or will be done so in the near future.
Bethwaite is associated with the development of the 49er class, and in his first edition of the book he did include some polar plots for more traditional classes.
As far as I understand all of the appropriate 49er information is included in the new book. I am intending to get hold of a copy for myself. If you do not want to purchase anything, the older version may include something on the 18's. |
