Designed specifically for Optimist sailors, the Opti Sheet Block arrangement is a ready-to-use, no-fuss sheeting system that's both efficient and easy to install.
This system features a combination of ø30 mm and ø40 mm Soft-Attachment Blocks, connected using durable ø3 mm Dyneema® loops and a high-quality stainless steel snap shackle.
The upper block and snap-shackle are separated 150 mm to reduce the amount of line the sailor needs to manage, making trimming easier and faster.
The loops are securely fixed using our Tie-on Inserts, ensuring a solid, tangle-free setup without the need for knots or splicing.
The Opti Sheet Block (Product code: 404-101-70R) is available now at a retail price of £72.00 excluding VAT.
