The Parallel Rule Captain Fields Pattern meets the need for quality construction and thoughtful design. Something that is demanded by those involved in navigation and where precision is paramount.
It’s crafted from 6mm thick acrylic, a material renowned for its clarity and durability. This makes it ideal for students studying navigation and experienced navigators alike. With carefully etched protractor markings and compass points on both sides, readings can double-checked, ensuring accuracy.
One of the standout features of this rule is its bevelled edges on all four sides. These aren’t just aesthetic – they serve a purpose, allowing the rule to sit smoothly on charts or drawing surfaces, ensuring each line drawn is accurate. This can be crucial for students learning to plot courses or for navigators working under real-time constraints, where misaligned markings or slips could lead to costly errors. The bevelled finish, combined with solid brass links, enhances both the usability and longevity of the rule.
Navigational equipment often encounters tough conditions, from damp maritime air to fluctuating temperatures. As a result, the rule is built with non-corrosive metallic components to stand up to these environments. The solid brass links offer durability and add a classic aesthetic touch. All other metallic parts are made with materials resistant to rust and corrosion. This attention to detail ensures that the rule not only retains its accuracy but also requires minimal maintenance.
