subject:shroud length
Think of the triangle formed by the mast, spreader and that portion of the shroud above the spreader as a right triangle. Using the formula A sq plus B sq equals C sq where A is the verticle leg (mast), B is the base leg (spreader) and C is the hypoteneuse (shroud) you can determine the length of the shroud above the spreader for standard length and also for the shortened spreader. Subtract the difference from the total length and you will be close. The length of the shroud below the spreader will increase some, too, but not enough to make a major difference. If you want to figure it, B would be the distance from the mast to the chainplate minus the length of the spreader. There it is. Clear as mud.
From the Ullman Tuning Guide:Spreader Length
"The spreaders should be cut to the minimum length of 25 inches, measured from the side of the mast."I think 25" is the length to which most of the spreaders have been cut (from the factory 29").
