The mast tube will be a one or two-piece section with a side lap join. Mast shells will be made as separate front and aft pieces. These forward & aft shells are co-cured with release film in situ to create an integrated high precision join overlap, allowing them to be separated post cure for internal fit-out. All reinforcing will be internal allowing for minimal external fairing requirements.

This method, combined with high precision female tooling, provides the lightest and cleanest possible tube section, resembling aerospace technology, currently unprecedented in this sector.
