The Barton Marine Size 3 Vang System N03900 is a pre-rigged vang for sailboats that includes a snap shackle head and a 24' control line. It provides controlled vang load and simplified boom tensioning so you can trim sail shape and reduce weather helm.

When vang control is inconsistent you get poor sail shape and harder handling. This Size 3 Vang System solves that by combining a ready-to-install snap shackle head with a fixed length 24' line to reduce installation time and ensure repeatable vang performance for small to medium rigs.

• Pre-rigged 24' line for faster installation
• Snap shackle head for secure quick connection to boom
• Sized for common small to medium sailing rigs (Size 3 load range)
• Reduces boom vang play for consistent sail trim
• Suitable for use with standard vang sheaves and deck fittings

Compared to loose parts or generic vang kits this system arrives ready to fit and minimizes measuring and splicing. You can install it as a direct replacement or as an upgrade to older vang setups to regain precise vang response and control.

Manufactured by Barton Marine and sold under part number N03900 this vang system features marine-grade hardware and line designed for rigging use. Check fit with your boom and sheave sizes before purchase. If you need help confirming compatibility provide your boat model or vang measurements and you can order with confidence.
