Antal Mainsheet Block with Cam Cleat for E8/60
The Antal Mainsheet Block with Cam Cleat for E8/60 forms the base of Antal’s powerful 8:1 mainsheet system for yachts up to approximately 36 feet. Engineered for high mechanical advantage and smooth sail handling, this block combines a 60 mm primary load-bearing sheave with a triple 50 mm block mounted directly above it—complete with a becket for clean sheet termination.
An integrated cam cleat allows for easy mainsheet capture and release, making this a compact and efficient solution for cruisers or club racers seeking greater sail control. Sold individually, it’s ideal for sailors upgrading or reconfiguring their mainsheet system while retaining existing boom blocks.

Boom-End Block Requirement
To complete the 8:1 tackle system using this block, you will need:
-
1 × Triple block (50 mm sheaves)
-
1 × Single block (50 mm sheave)
Because the sheet starts at the becket built into the lower block assembly, the boom blocks can be simple non-becket types.
Compact, efficient, and high-performing, the Antal E8/60 lower mainsheet block is ideal for sailors seeking enhanced sail control and smooth trimming in a durable, upgrade-friendly format.
