My calcs suggest that would be around 14.2kgs for a 8.6m mast section.
Similar to wouters calc on the 150 x 63 section.
Are you the mast is the lighter Tiapan section.?
That's right in the range of what we have been getting. The history being spread around here, is that the 2 sections are the same with the exception of the added riblets to increase stiffness. From a cost point that makes the most sense as well.
