I think any boat is prone to this since line tails started getting hid away. I've just made it part of my between-race routine to even everything out - jib sheet, downhual, rotation - in preparation for the next sequence. My skippers hear me call it "housekeeping." The AHPC downhual is particularly sneaky because you don't just run out of line - the blocks bottom out where you don't see them. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
