Harken 80mm Single Element Block Mastbase w/Swivel

The 80mm Single Element Block Mastbase with Swivel is engineered for durability and performance in marine applications. Designed to withstand the harsh marine environment, this block ensures smooth and reliable operation of your boat's mast and rigging system.

Outstanding Durability and Strength

Crafted with sideplates that merge forged aluminum and compound curves, the Element block delivers superior strength and rigidity. Its contemporary design not only enhances the aesthetic of your vessel but also ensures robustness, making it ideal for both recreational and professional marine use.

Innovative Design for Optimal Performance

The Element block features a minimalistic metal structure that safeguards the sheave while incorporating a reliable journal bearing. This efficient design reduces weight without compromising on strength, providing a cost-effective solution that is significantly more affordable than previous models.

Corrosion-Resistant Construction

All sideplates undergo a hardcoat anodizing process to resist corrosion, ensuring longevity even in salty marine environments. The composite bearing sheave further enhances corrosion resistance, promising a long service life and consistent performance under demanding conditions.
