ratchet blocks

Achieve Perfect Trim and Control

Ratchet blocks are all about trim, control, and reliable power transmission on board.

When choosing, breaking load, diameter, and compatibility with your existing hardware are important. Ball bearings run smoothly under load, while plain bearings are robust and low-maintenance.

This ensures sail operation remains precise, smooth, and durable.

Discover variants, materials, and designs built for marine use. This way, you'll find equipment that remains reliable on board – season after season.

Deine Fragen / Unsere Antworte

What rope diameter can a ratchet block handle?
This varies depending on the model – typically between 6 and 14 mm. You can find the recommended rope diameter in the respective product description. A rope that is too thin can slip, while one that is too thick will jam and damage the mechanism.
Can I use a ratchet block as a normal fairlead block?
Many ratchet blocks can be switched to free-running – in which case the block behaves like a regular fairlead block. Models without this function only ratchet in one pulling direction, which can make hauling in the other direction difficult.
How often do I need to maintain the bearings of a ratchet block?
After intensive saltwater use, rinse the block with fresh water. Ball bearings benefit from an occasional drop of bearing oil – how often depends on the intensity of use. Plain bearings require less maintenance but should be checked for dirt and sand deposits.
How do I attach a ratchet block to the deck if there is no suitable pad-eye?
The safest method is to re-bolt it through with a backing plate under the deck so that the load is distributed over a larger area. Adhesive connections or simple screws into GRP without a backing plate are not suitable for dynamically loaded blocks. When in doubt, it's worth consulting a local boat builder or rigger.
