spreaders, shrouds, and trigonometry

[Douglas]

Ahoy Brion,,,, on double spreader rigs,,,,, what happened to the "bisect the angle" rule of thumb, for setting the spreader "up" angle ?

Seems to me that the upper spreader has to be set "up" more of an angle, because that cap shroud does such a radical angle back to the mast head once it leaves the upper spreader tip .



BTW ,,,, I have been using the tarred marline that is sold at WM ,,,, and it has been breaking when I draw down on my constrictor knots,,,,, is there another stronger lashing line available, and just how can I find some, way out here in Singapore ?

Also do you still use a electrical friction tape on the shroud, under the constrictor knots, or have you found some other tape better to use ?

Also, just how much lose a fit, or movement at the spreader base, is acceptable ,,,, like when the mast is on the horse's , and the spreaders are attached, but not loaded,,,,, what kind of spreader tip movement is acceptable ?
