Red Flex Spar Set – Ultimate Racing + A-250 Starter Package – Optimast

The Optimast Red Flex Spar Set is a highly dynamic Optimist rig designed for demanding conditions, especially open water and wave sailing. This set fills the performance gap between the Blue and Red ranges, offering increased flex and responsiveness while maintaining excellent control and balance.

Built around the Red Flex Ultimate Racing mast, boom, and sprit, this spar set delivers an active rig that adapts smoothly to changing pressure and wave patterns. Coaches and competitive sailors often choose this configuration when pairing lighter sprits with responsive spars to keep the sail efficient and fast through waves.

Supplied with the A-250 Starter Package, the Red Flex Spar Set is fully race-ready straight out of the box and compliant with IODA class rules.
