Product Details

The Harken 340 is a 29mm Carbo Air® single block with swivel that allows either a 2:1 or 3:1 purchase system. Designed for high-performance sailing applications, this block combines lightweight composite construction with exceptional strength and reliability.

Key Features:

  • 30% lighter and 60% stronger than equivalent Classic blocks
  • UV-stabilized, fiber-reinforced composite sideplates for maximum durability
  • Low-friction sheave optimized for small-diameter control lines
  • Integrated swivel for improved line lead and reduced wear
  • Compact design ideal for space-limited installations
  • High working load capacity for demanding sailing conditions

Applications:

  • Jib and mainsheet systems on high-performance dinghies
  • High-load control lines on small keelboats
  • Racing applications where weight savings are critical
  • Any system requiring reliable small-diameter line handling

Award-winning Carbo AirBlocks® have earned both the Dame Award and Sail Magazine's Freeman-Pittman Award for innovation. These blocks deliver a proven strength-to-weight ratio that racers and performance sailors depend on. The 29mm sheave size works perfectly with modern small-diameter, high-tech lines favored in competitive sailing.

Part of Harken's comprehensive Carbo Air series, the 340 block represents decades of marine hardware engineering expertise combined with advanced composite materials technology.
