Hall Brick House Shroud Adjustment System
Threaded turnbuckles will soon be a thing of the past, thanks to the Hall Brick House shroud adjustment system. The genius of the Hall Brick House is that adjustments are made by inserting or removing shims in a manner similar to the bricking system on an adjustable mast step - no tools required.
The system was developed as part of Hall's continuing quest to reduce windage. The first improvement we made was to move the shroud terminations inside the mast tube. Hall's single-piece seamless construction process made it possible to develop an internal load-sharing system that makes use of the mast walls and spreader bars. Turnbuckle systems are impractical for internal adjustment, so Hall engineers developed the unique shim system.
The Hall shim system offers a wide range of adjustment and is approximately one-third the weight of a comparable screw-driven system. Individual shim plates are produced at thicknesses based on the former turnbuckle turn ratio. For example, a 25mm plate equals 16 turns. The shims are color-coded according to size/number of turns. When sailing, the entire assembly disappears into the mast section when covered with a thin carbon plate, significantly reducing aerodynamic drag. At the deck level, turnbuckles are eliminated and replaced with eyes that are lashed to the deck.
Improved rig tuning communication, ease of adjustment, highly accurate and repeatable settings – the Hall Brick House delivers all of these advantages along with significant reduction of both windage and weight. Available on all new masts. Call for a quotation. |
