The sprit halyard is one of the most important sail controls onboard an Opti. The more you  can actively adjust the halyard tension to match conditions, the better your boat will sail. This is why it’s super important to have a low-friction system that’s easy to adjust while you’re sailing. Check out this video featuring Blockhead ambassadors Chapman and Jack as they install the key components to optimize Jack’s Opti sprit halyard.
