Tariff Updates

We are observing how the tariffs are behaving. Lots of our products are imported from Europe and some of the manufacturers are not providing heads up about price increases. We will do everything in our power to hold the best prices, but please consider that in these uncertain times we may be forced to increase the prices without previous notification.

We really appreciate your understanding and look forward to working with you.

What does this mean for you?

  • Some imported products may show a higher price than usual.
  • Prices may change as shipping rates adjust globally.
  • We are committed to providing the best possible pricing and transparency at all times.

How we’re handling it:

  • We only adjust prices when absolutely necessary.
  • We continuously monitor shipping rates and update pricing accordingly.
  • We’ll clearly notify you if a product is affected by tariffs.

Questions? Feel free to contact our team for any clarification or assistance.

Clew Blocks: Symmetrical both sides

Reefing Blocks: One side is flat so that it can lay flat against the sail.

Our range of clew/reefing blocks are unsurpassed for quality and performance. The bearing system has been engineered to provide smooth running reliability under the most demanding conditions, whilst the aluminium alloy side plates provide strength without adding excessive weight. Both the clew and reefing blocks are available in 4 sheave sizes.
