Antal Mainsheet Tackle 7:1 – Complete, Sheaves 75 & 60
The Antal Mainsheet Tackle 7:1 – Complete, Sheaves 75 & 60 is a high-strength mainsail control system designed for yachts up to approximately 40 feet. Providing a 7:1 mechanical advantage, this configuration delivers increased power and precision, ideal for larger sail plans or heavier loads where smooth, effortless trimming is essential.
This system begins with a double block with becket on the boom, where the line is anchored and routed through the tackle. A lower block houses a 75 mm primary sheave and integrated cam cleat, while a triple 60 mm block is mounted just above to extend the purchase. A final single 60 mm block is mounted forward on the boom, completing a carefully balanced sheave layout featuring six 60 mm sheaves and one 75 mm sheave.
