To avoid trying to hold a ruler or tape measure steady in just the right place - and not yet having the experience to tune only by eye n intuition! - I've created this 3d-printable gizzmo for more easily making repeatable rig measurements: On circular booms ~5-11mm dia., for measuring foot depth (e.g. IOM/DF95/DF65). Against the mast, to measure gap to jib boom ("3 fingers" is a subjective measurement!) Against the backstay, to measure leech twist. Measurements can be taken between inside-edge(s) if you prefer, or the V underside allows for measuring from the centreline regardless of spar diameter. (Just add/subtract radius if necessary). Happy to hear any ideas for improvements. A variation to sit on SAILSetc rectangular boom could certainly be done - the relative dimensions just don't allow a one-fits-all. The g-code file is offered for free, but please don't make/sell for profit. If you find it useful then a modest donation to https://prostatecanceruk.org/ would be kind.

IntroductionFirstly, we must express our gratitude to the MYA for providing us with our own Forum space to support our business. The MYA makes significant contribution to all stakeholders in Radio and Free Sailing, and we are sincerely appreciative of their support. Thank You to Our CustomersWe would also like to extend our thanks to everyone who has chosen to become a customer of Cat Components. Your continued support and the positive feedback you share are genuinely valued and greatly appreciated. Our BackgroundCat Components was established in 2025 after Nigel Brown of Catsails and I began working together to address several rig component challenges we were facing. It soon became clear that these issues were not unique to us, as many others we spoke to were experiencing similar difficulties. Initially, we promoted our products via Catsails.co.uk and towards the end of 2025 we made the decision to launch a separate online store for components and additional 3D printed products, CatComponents.co.uk . This allowed Catsails to continue to focus on the sails and accessories which it has successfully supplied for many years. Product Development and Customer EngagementOur range of products is continually growing, and we actively welcome input from both current and prospective customers. Whether you have suggestions for improvements or ideas for new products, we encourage you to get in touch with us at info@catcomponents.co.uk . We are eager to hear your thoughts and recommendations. We are committed to serving the UK and international Radio and Free Sailing community for many years to come.
