Does anyone know the dimensions of the inside of the mast? Dimension A and B in the attached picture. Mk 1.5 No Furling. I want to build a brace to help me install new conduit in my mast this month before we put the boat in the water and my mast is 265km away at the moment. Outside dimensions would be fine too... this won't be a precision tool when I build it and I'm sure it will need some field modifications.
Bonus question -how thick is the mast material (to make sure I have the right rivets).
