the instructions for the lug rig specifies that the boom and yard will be tapered down in the last 20 inches on both ends. I am assuming this is an equal taper on all sides. sounds like a silly question but I assume it makes a difference regarding how the sails were built. were the lug rig sails built with the design that the ends of those spars would be tapered away from the sail? Had I not seen that instruction I would have assumed the edges of the spars would be straight where they meet the sail. That question does not pertain to the mast (where the directions very clearly state to taper all sides) since the lug sail is not attached to the mast so that shape has no impact on the sail shape.

sorry, I grew up sailing a larger boat and a big part of my job was to make sure the mast shape was adjusted with all kinds of things for shaping the mainsail, so the impact of a spar's shape (even little changes) on sail shape is a big thing for me. With the size of these sticks it may not matter much, or more likely, the sail design already relfects these tapers (taking out a bit of depth out of the belly of the sail which the end tapers will then add back, so the sail design depends on making the tapers on the edge of the sail).

any help?

thanks
