He has recorded in the blog post-race analysis of races he sailed this year with comprehensive information on wind shifts, courses and all significant events, good and bad, during each race. Each report includes a chart of the race area with a compass rose. I know I ought to do a better job of analyzing each of my races if I want to identify weaknesses and work on them. His example might actually inspire me to take some action.
Many of his posts such as Thinking Inside The Box cover advice on racing techniques that is original as far as I know. At least it's not stuff that I've come across in that form before. And I'm a voracious reader of any scraps of information that might be of help to me on the racecourse.
And he's also built a set of links to all sorts of useful racing resources on a diverse set of subjects including weather, sail trim, rigging and tuning and all sorts of other good stuff. Many of these are new to me so I'm slowly working my way through them and learning all kinds of good stuff.
Not to mention he's also compiled a list of other sailing, racing blogs. And surprise, surprise... Proper Course made the list. What a guy!
