I dont have time to let a sinker over the bow and time the knots in the line over <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />. Can you give me your better way of accurately measuring boat speed Jimmi? <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> I will have an F18 and it would be nice to see accurate data from top crew races to help understand the strengths and weaknesses of the different brands of F18
