Re: looking for help on where to set my jib block
Neither of those responses will get you all that close to the optimal lead position. Most sails have at least two pairs of telltales on the luff of the sail, one roughly a 1/4 way up from the foot and the other roughly a 1/4 way down from the head, with both located roughly 18 inches aft of the luff on a boat like yours. (If you don't have them you should add them.) To check the proper lead (sheet angle) you should adjust the sail for a beat, and slowly turn up towards the wind watching both the upper and lower telesales. The windward telltale on both the top and bottom telltale should break (stops flowing aft) at the same time. If the top telltale breaks first you need to move the block forward. If the lower telltale breaks first the lead needs to be moved aft. The optimal adjustment has the upper and lower telltale breaking at the same time. This position will vary with wind strength and gradient wind conditions (variations in wind speed and direction with height above the water).
