The Ultimate Guide to Purchase Systems and Mechanical Advantage.
In this guide, we’re breaking down the nitty-gritty of purchase systems, from the straightforward simplicity of the “simple” system to the power-packed intricacy of the “compound” system. We will also take a look at how to calculate a purchase system and the steps you should take to design your own.
A purchase system is like your boat’s backstage crew, working behind the scenes to make sailing a breeze. It involves blocks (the unsung heroes) and ropes, creating a setup that multiplies your muscle power, making sail control and rigging adjustment a piece of cake.
Let’s start with the basics – the “direct” approach. In a simple “direct” purchase system, there’s just one block, one line (rope), and one straightforward mission: to control the load. It’s a 1:1 ratio, meaning the force you exert is the force felt by the load. Perfect for tasks like raising the centreboard on a dinghy or adjusting basic sail tension. Simple, effective, and great for when you need no-nonsense control.
