Calculation for crossarm stays on cat

[Brion Toss]

Hello,
It's all about angles, and crucial ones they are, in this case. Assume that the striker stay needs to be able to resist the full breaking strength of the forestay. This is vital. The size of the striker stay will then vary with the length of the crossbeam and the height of the striker. The wider the angle that is formed, the bigger the striker stay needs to be; it's a basic trig exercise. If you aren't familiar with the calculations involved, be sure to be in touch with someone who is. Contact our shop for a consultation if you want me to do it, but by all means do it right; that stay is keeping the mast out of the cockpit, among other things.
Fair leads,
Brion Toss
