Twisted Spar

[Brion Toss]

Hello,
First, it is always possible that at least some of the mast twist had nothing to do with the grounding; correlation v. causation.
Next, stresses might easily have affected places you haven't noticed yet; follow the flow of forces, look closely at any place that they might have concentrated.
Third, most of those hulls had very, very overbuilt masts, with resultant stability issues; you might be better off with lighter sticks.
Finally, consider going over the rig, including diameters v. loads, before replacing anything, including tangs, throughbolts, wires, etc.
Fair leads,
Brion Toss
