  • The 25 x 6 mm sheave is sized for medium-diameter spinnaker sheets and guys on small to mid-size sailboats.
  • Recessed body design retains the line within the block, preventing unintended disengagement during gybes or tacks.
  • Optimized for the dynamic, variable loads experienced in downwind spinnaker sailing.
  • SeaSure construction provides reliable performance across repeated load cycles in racing and cruising use.

The SeaSure single-pulley block with 25 x 6 mm sheave and recessed spinnaker configuration is designed for spinnaker pole and running rigging applications on sailing vessels. The recessed body format keeps the line contained and reduces the risk of accidental release under load.
