Antal E7/60 Mainsheet Tackle 7:1 – Complete

The Antal E7/60 Mainsheet Tackle 7:1 – Complete is a compact, high-efficiency mainsail control system designed for sailing yachts up to approximately 36 feet. Offering a 7:1 mechanical advantage, this system provides increased trimming power and finer control compared to a standard 6:1 setup, making it ideal for higher loads or more precise sail adjustment.

Built around Antal’s Size 60 block platform, the system combines a 60 mm primary sheave with 50 mm secondary sheaves, delivering smooth operation, efficient load distribution, and low-friction performance.

System Configuration

This complete mainsheet system consists of three matched components:

• Lower Block:
  Antal mainsheet block with 60 mm primary sheave, 50 mm triple sheave assembly above, and integrated cam cleat. This forms the base of the system and provides secure, responsive mainsheet control.
• Boom Blocks:
  • 1 × Single block (50 mm sheave)
  • 1 × Double block with becket (50 mm sheaves)

The becket on the boom-mounted double block acts as the starting point for the mainsheet, enabling the additional purchase required to achieve the full 7:1 configuration.

Key Features

• 7:1 Mechanical Advantage
  Provides increased power and finer adjustment, ideal for managing higher mainsheet loads.
