Optimist Spars - Medium Pro Set - Flex Mast/Stiff Boom

Multiple Championship winning combination for Racing sailors 40–45 kg. A very common high-performance setup. Stable boom, controlled mast bend.

• Pro Flex Mast: Bends earlier in gusts, flattening the sail automatically.
• Makes the boat easier to control in stronger or gusty conditions.
• Pro Stiff Boom
• Extreme stiffness-to-weight ratio. Transfers load efficiently into the mast.
• Pro Sprit: Larger 28mm tube with thin walls for extra stiffness and lighter weight.
• Supplied complete with rig pack.

This is a very successful setup and can extend up to 50Kg sailors. The stiff boom and sprit work together to force bending loads into the flex mast. The mast bends predictably and the sail depowers smoothly. Bending the mast flattens the sail while keeping a tighter leech to maintain pointing.
