Mainsheet systems, simple yet vital hardware, play a crucial role in sailboat operation due to their constant use. A block and tackle or ‘purchase’ system is a form of mechanical advantage, where the input force is multiplied through a series of pulleys or blocks to create a much larger output force. Trying to understand how to achieve different purchase ratios might seem daunting to the uninitiated, but it’s quite straightforward once you know some basic principles. In this blog we will guide you through different purchase systems used on modern sailboats.

Today we are speaking about deck hardware and rig setup to Max Kohlhoff, the winning helmsman of the 2023 Star Worlds. With Ole Burzinski from Flensburg Yacht Club, onboard Playmate, they recently scored two bullets out of six races in Scarlino, finishing the championship ahead of double Star World champion Diego Negri. They now join the long list of Star World Champions, that have raced annually since 1923, to claim this prestigious title.

We have previously reported on the benefits of composite backstays: to reduce weight aloft and increase performance. An effective control system to finely tune backstay load is equally important, particularly for a race yacht. In this blog we look at 3 popular configurations for backstay purchase systems using block and tackle. 

If there is one brand name that is synonymous with quality and innovative marine products specifically designed and engineered for sailors, it’s Ronstan. 

In this blog we take a quick look at what is new and/or interesting in the sailing block world in 2023.

Deck hardware has come full circle. Now, designers favour simple designs that make use of high-performance materials over complex concepts. We spoke to Nicolas Goldenberg of Morfrac Systems, the mind behind the disruptive morfblock, about the evolution of deck hardware and his predictions for the future.
