On the topic of stiffness, what sort of deflection are ppl getting in their main beam under full rig tension? And, what deflection are ppl getting in their bows (transversely) under full rig tension?

I found it difficult to maintain rig tension on my ply mozzie because there was heaps of deflection in both of these. I managed to increase the dolphin striker tension which helped reduce the main beam deflection.


The mossie uses a small [55mm?] square section for the front and rear beam which in itself isn't very stiff.
