Thanks Marc , <br> All catsailors appreciate the efforts and valuable information provided . <br> <br> Reallize the scale may not equate evenly through a wide range of boat weights and sail areas , and will vary greatly in each wind strength , -we would have to establish a good average . ----weight to sail area formula , -or proposed scale ,but believe 10 lb increments from 420 existing cats down to potentially new 320 lb cats may cover completely the range into the future . <br> <br>-Would also like to see an exciting fast class evolve , like the skiffs . <br> <br> Carl<br><br>
