If the top one is fluttering move the sheeting block forward a bit. Check the telltale on the leeward side, it should also be streaming aft, lying still and be parallel to the windward telltale.Īt this point, check all telltales top to bottom, If they are all performing the same the headsail is sheeted in properly and you are “in the groove”.

I would want telltales near the luff of the foresails(s), maybe a foot back from the forestay, and along the very leech of the main. It's often said that you should trim the front of the jib and the back of the main, so that's a good place to start.
