Description
Tapered Opti Mainsheet Robeline's tapered lines feature outstanding properties such as excellent abrasion resistance, extra low stretch, and the use of top-quality polyester. A specialized line, the Opti (Optimist) mainsheet is double tapered (thinner at the ends, thicker in the center) which provides a better grip.
The smaller line diameter at the ends reduces friction in blocks and sheaves. Constructed of a mix of Dyneema® with a PA/PES (polyamide/polyester) yarn for high loads, low stretch, improved elongation and excellent grip.
This sheet is not symmetrical, one taper is longer than the other. The long taper runs through the blocks on the boom, the shorter taper runs through the cockpit sole blocks.

Sailing — frequently asked
- How do I size a block for my sailboat?
- Match the block to the line diameter it will carry and to the working and breaking loads of the system (sheet, halyard, control line). Makers publish load ratings and line-size ranges — choose a block whose working load comfortably exceeds the real-world load, without going so large it adds needless weight.
- What is running rigging?
- Running rigging is the moving lines that control the sails — sheets, halyards, and control lines — as opposed to standing rigging (the fixed wire that holds up the mast). Running rigging should be matched to the boat’s blocks, clutches, and winches for smooth, reliable sail handling.
- How do I maintain sailboat winches and hardware?
- Rinse with fresh water after sailing, keep sheaves and bearings clean, and periodically service winches (disassemble, clean, and re-grease per the maker’s instructions). Marine-grade stainless and good maintenance keep hardware working smoothly when loads are high and timing matters.
