Allen Acetal Pivoting Mast Step Base & Bar

 

Acetal Pivoting Mast Step Base & Bar

The Acetal Pivoting Mast Step delivers enhanced performance through refined engineering. Designed to provide smoother mast articulation and improved structural efficiency, it allows the mast heel to pivot freely - promoting a more consistent and controlled mast bend profile. This results in optimised rig setup, superior sail shape, and reduced loading stresses across the deck.

The updated design takes performance a step further, offering several key advantages over traditional tenon-style mast steps:

Performance Advantages
  • Centralised Load Path – Compression loads are taken directly through the centre of the mast tube, eliminating adverse bend effects caused by offset compression in older tenon types.
  • Superior Torsional Resistance – The design effectively resists twisting forces from the gooseneck, maintaining alignment and improving rig stability.
  • Precise Spreader Geometry – Exceptional torsional stability ensures spreader settings remain accurate, even under dynamic sailing loads.
  • Durable Round Bar Design – The stainless-steel round bar is highly resistant to wear. Any wear that does occur after several seasons can be easily corrected by replacing the heel plug.
  • Optimised Vang Load Transfer – The main kicking strap (vang) loads are efficiently transmitted through the main tubular bar, maintaining consistent tension across the mast’s raking range.
  • Customisable Fitment – The system can be easily configured for specific classes, with the option to add extra fixings if required.
 
Key Features
  • Stainless Steel Pivot Bar – Supports mast compression loads, provides the heel pivot point, and allows lines to be attached through the tube.
  • Lightweight Acetal Construction – Offers a cost-effective yet durable alternative to aluminium, with excellent wear and impact resistance.
  • Sloped Design – Prevents the jib from snagging during tacks for smoother manoeuvres.
  • Halyard Access Hole – 7mm hole to route a halyard below deck if required.

Compatible with various mast heel plugs are available to suit the most popular mast profiles:
AL-9250, AL-9251 & AL-9252
