Buy it and you will shower me with praise!! (G) I did all my navigation chart work in the cockpit in seconds and never used a parallel rule in 6 years of cruising. Next to the miracle cloth this is the holy grail of under $20 must have boat items!! This and some dividers are all you need.
For those of you who I've made curious...here's the one page "operators manual".
That is so cool! I'm going to order one tonight.
