Rope guides and grommets guide the rope's path through a specific point on the deck in a controlled manner - unlike blocks, guides do not contain a rotating part, but the rope slides directly through the guide, which is especially suitable for points where the change in direction of the rope is small or where minimizing friction is not as critical as at the actual bend point.
Harken manufactures aluminum rope guides in several sizes: 12mm and 16mm basic models, as well as double and triple versions in both sizes, when multiple ropes need to be guided from the same point on the deck in parallel. The larger guides (75mm and 125mm) designed for jib use are sized specifically for guiding jib or genoa corner ropes, where the rope is typically thicker and the load is greater than on smaller trim ropes.
When choosing a rope guide, it is important to consider both the thickness of the rope and the steepness of the change in direction at the guide – too steep an angle increases friction and wear, even if the guide is in principle suitable for the thickness of the rope. Double and triple models save space on the deck when several ropes need to be guided from the same area, but they also require more careful planning regarding the mutual arrangement of the ropes so that they do not get tangled in each other during use. Jib-sized guides are sturdier and designed to withstand greater continuous loads than smaller trim rope guides.
The jib-size rope guides (75mm and 125mm) are considerably more robust than the smaller trim rope guides, as the genoa and jib ropes typically carry the majority of the sail’s pull and therefore require a more durable guide solution. When installing double and triple models, it is worth planning in advance in which order the different ropes will pass through the guide, so that they do not cross or tangle during use – this is especially important if several moving ropes pass through the guide at the same time. The aluminum construction is lightweight but still strong enough for most sailboat needs, and the anodized surface provides good protection against both salt water and UV radiation. Check the inner diameter of the guide carefully against the thickness of your own rope before ordering.
Please check the inner diameter of the guide carefully against the thickness of your own rope before ordering to ensure the best compatibility.

Ask our customer service for advice if you are not sure about choosing the right size based on the thickness of your rope and its intended use.
