Upgrade your Optimist mainsheet system with this ultra-efficient, lightweight block setup designed for sailors who want maximum feel, control, and responsiveness on the water. The Opti Mainsheet Blocks combine Allen’s 40mm and 30mm dynamic tii-on blocks to deliver exceptional low-friction performance in a compact, race-ready configuration.
The two blocks are positioned as close together as possible using a precision-made soft shackle, improving the sheeting angle and allowing smoother, cleaner mainsheet movement. Thanks to the stainless steel ball bearings inside the Allen dynamic blocks, you’ll experience noticeably reduced friction—making it easier to trim, ease, and play the mainsheet for longer periods with less fatigue.
To complete the system, the blocks are hand-spliced onto a high-quality snap shackle for fast and effortless attachment to your mainsheet bridle. All splicing is done using 2mm SK99 Dyneema, ensuring an incredibly lightweight, zero-stretch, and highly durable connection.
A top-tier upgrade for any competitive Opti sailor looking to sharpen their performance and gain a more responsive feel from their mainsheet system.
