Tangs

Each mast design is unique and mast making today is more advanced than ever. Regardless of the design, the
interface of the mast and the rigging system is always critical to the safety and performance of the yacht and its crew.
Navtec’s range of tangs provides solutions for managing that interface

K550 Micro Stemball Tangs

Provides a custom fit for every mast by matching the height of the backing-plate sleeve to the mast wall thickness (T).  Excellent choice for both carbon and aluminum masts. The cap is constructed from high-strength stainless steel alloy; backing plate is made of 316 stainless for unsurpassed corrosion resistance. The K550 is also available in a Grand Prix clamping version, which uses the same cap, but with aluminum backing plate and clamp bushing.
