After replacing all standing rigging and furler with a selden 206 I've noticed some slop in the head stay. The aft lowers are slack as well after at strong year of sailing. the problem is there is no turns left on the backstay to tension out the forestay. Both rear turn buckles only have a 1/4 turn before they bottom out. Sighting up the mast there is a very, very slight forward bend foreward. Not good. Called the rigger who did the install and he asked what the rake of the mast is. I assume there is a design rake number for the rig. Cant seem to find it - any ideas?
