Anti-torsion climbing ladder for 14 m masts (ladder length 12.60 m)

Made of webbing tape and aluminium steps. The ladder has to be fixed at the mast base with the fixings supplied (ideally fixed under the boom goose neck fitting) and has then to be put under tension by means of a halyard winch. The ladder will be stiff and stable: even if you lose your balance, the ladder keeps still and doesn't twist.
The total length of the ladder shall be shorter than the mast length for utmost stretching. When the upper end of the ladder is fully stretched, a man standing on the uppermost step should have his thorax at the same height of the masthead. Adjust the ropes for the correct length.
