Common Concerns Answered
Is the 'T-style' body less aesthetically pleasing than modern designs?
While the T-style body offers a traditional aesthetic preferred by many mariners, some may find it less streamlined than contemporary designs. However, its functional integrity and robust material composition are its primary benefits for rigging.
Will extreme saltwater exposure cause issues with the bronze and stainless steel combination?
The forged silicon bronze and 316 stainless steel combination offers excellent corrosion resistance. However, like all marine hardware, diligent rinsing and occasional maintenance in harsh saltwater environments will ensure longevity and prevent any potential issues.
Are there concerns about the non-galling properties?
The combination of forged silicon bronze and 316 stainless steel is specifically chosen for its non-galling properties, which is a significant advantage in preventing seized threads and ensuring smooth adjustment, even after prolonged exposure to marine conditions.
