Can you tell me the wall thickness of my SC20 std rig mast? I measured 2mm at the luff track, but not sure if the walls are the same. Is the same extrusion used on the tall rig? Thanks!
Dave,
The wall thickness on older masts was approximately 2.36 mm
The newer mast extrusions ( after 1987) has a same wall thickness but I changed the sail track profile.
The new mast has a sail track with an internal profile that is round.
Dave,
The tall rigs all had the same profile and wall thickness. Starting in 2008 all tall rigs (38' 6") will be in carbon. Aluminum will no longer be available.
