North Sails

North Ultimate Carbon Boom

Description

North Ultimate Carbon Boom is the ultimate carbon boom for windsurfers who want maximum stiffness and strength at minimum weight. The boom is designed for wave and bump & jump sailing, where every precise steering input needs to transfer directly to the sail. With a unique combination of design, materials and technology, you get a boom that responds with instant feedback to the slightest hand movement.

At the core of the technology is the FEM-optimized lay-up: Using the Finite Element Method, carbon material is placed exactly where the load is greatest, while material is removed from low-load areas. The result is a monocoque front end and a one-piece carbon-reinforced boom head that fits all mast types - RDM (with shim), MDM or SDM. The variable diameters of the boom arms provide a comfortable, ergonomic grip, so you stay in control throughout your session.

  • FEM-optimized lay-up: Material is only placed where it improves stiffness and strength - the rest is removed to save weight.
  • Monocoque front end: The construction provides a stiff, responsive front end that transfers power directly to the sail.
  • One-piece boom head: A carbon-reinforced head that fits all mast types - RDM (with shim), MDM or SDM.
  • Wave-optimized boom curve: The shape and width are tailored to wave sails, with a rounded front section for a more ergonomic and efficient sailing position.
  • Variable boom arm diameter: Ensures a comfortable grip and reduces fatigue on long sailing trips.
  • Fiber-reinforced clips and pins: Fiber-reinforced plastic adjustment clips provide secure, durable length adjustments.

  • Care & Maintenance

    Caring for your North carbon boom

    Rinse the boom with fresh water after every session - especially after sailing in salt water - and let it dry completely before putting it away. Salt residue and moisture gradually damage both the metal parts and the carbon surface.

    Wipe the boom with a soft cloth, and avoid harsh cleaning products or using a pressure washer directly on the clips, pins and boom head. Regularly check the adjustment clips, pins and outhaul system for wear, and tighten any loose screws to make sure the boom is always secure.

    Store the boom in a cool, dry place out of direct sunlight - preferably in a boom bag or away from sharp objects that could scratch the carbon surface. Don't leave it in a hot car or put heavy items on top of it, as constant pressure can damage the arms over time. It's best to store the boom assembled or partially tightened to relieve strain on the head.

  • FAQ

    Which masts fit the North Ultimate Carbon Boom?

    The carbon-reinforced boom head is made in one piece and fits all mast types: RDM (with shim), MDM, and SDM. So you don't need to worry about mast compatibility.

    Is the boom suitable for wave and bump & jump?

    Yes. The boom curve is optimized for wave sails, with a rounded front section that provides a more ergonomic and efficient sailing stance and smoother transitions in waves and strong winds.

    Why choose a carbon boom over an aluminum one?

    Carbon offers significantly greater stiffness and strength relative to its weight. With an FEM-optimized lay-up, the material is only placed in high-stress areas, resulting in a boom with instant feedback and direct steering response.

    How do I adjust the boom length?

    The boom is adjusted using clips and pins made of fiber-reinforced plastic, allowing for safe and quick length adjustment so you can fit it to your sail.

    What's the best way to maintain the boom?

    Rinse it with fresh water after sailing - especially in salt water - let it dry completely, and store it in a dry place out of direct sunlight. Check the clips, pins, and outhaul regularly for wear.

    Is the boom good for beginners?

    The boom is primarily aimed at experienced wave and bump & jump sailors looking for maximum precision and control. However, beginners also benefit from the comfortable grip and pleasant variable diameter of the arms.

    Does it really make the sail more responsive?

    Yes. The combination of a stiff monocoque front, carbon head, and optimized lay-up transfers every hand movement directly to the sail, giving you instant feedback and helping you get the most out of the sail's design potential.
