Get a used copy of Skene's Elements of Yacht Design. The spars and rigging
chapter has everything you need to know in order to size both the spars
themselves and the standing rigging. Barnes and Noble's online used and
out-of-print books department would be a good place to find a copy.

Does anybody know how to go about calculating the stresses in standing
rigging. I have an masthead sloop rigged 50 ' FRP boat. 4 lowers, 2
intermediates, 2 uppers, head & back stay. All inboard rigging. I'd
like to know the tensions in the various stays - vs the tensile
strength of the wires. Any ideas on how this is done?
