The 4 mm trimming line is a basic component of any windsurfing setup. It is used to adjust sail tension in mast extensions and boom trimming systems.
The 4 mm diameter provides a solid balance of durability and smooth handling through pulleys and rollers. It does not bind and allows accurate sail tensioning, making both rigging and on-the-water adjustments straightforward.
The 2 m length is a practical choice for most standard mast extensions, especially if you prefer a slightly shorter setup with less leftover line after trimming.
