Description
EasySea Olli™ - Snatch and Anti-shock Block 50x12 - Medium

A solid and robust snatch block, perfect for rerouting lines, craeting purchase systems or as a back up block for use if another fails. Built using aerospace materials, this block delivers superior performance onboard.

Crafted with a milled and anodized aluminum body, combined with shells made of advanced aerospace-grade polymers like SOLEF® (PVDF), and a Dyneema® soft shackle from world-leading brand Gottifredi Maffioli.
Every component is engineered to withstand extreme loads and harsh environments. The result? A block that is incredibly strong, durable, and built to perform.

Key Features:

  • Openable – Quick Setup, Anywhere
    • Thanks to its smart design, the two shells can rotate once the Dyneema® soft shackle is released, allowing the block to open.
    • This means it can be installed directly onto an already tensioned sheet — ideal for quick additions, inspections, or adjustments without the need to unthread the entire line.
  • Monolithic and Self- Lubricating – Zero Maintenance
    • No metal ball bearings, no removable parts. At the core of the Olli Block is a self-lubricating bearing made from two different aerospace polymers.
    • This results in a smooth, efficient, and maintenance-free system, designed to make life easier onboard.
  • Impact-Friendly – Protects your boat
    • The aluminum ring is enclosed within two polymer shells, so if the block hits the deck when unloaded, the impact surface is softer than typical boat finishes (gelcoat, wood, aluminum). That means no scratches, no damage — just peace of mind.
  • Dual Function – Block + Low Friction Ring
    • The central hole of the Olli Block is more than just a pass-through for the line.
    • It can serve as a fixed attachment point for creating a 4:1 purchase system, securing a spliced eye or soft shackle, or as a low friction ring to guide an additional line or deflected control.
    • Total versatility, compactly designed.
