"With the advent of modern synthetic line, like Colligo Dux, wire rope will be a 150-year anomaly in the history of sailing boat rigging."

New technology is the essential driving force behind Colligo Marine. The new line chemistries enable us to make our standing rigging with low stretch properties that surpass that of steel while taking advantage of the low weight and corrosion-free properties. New developments in titanium are bringing the price down and making this virtually corrosion-proof metal accessible to the average sailor. New manufacturing techniques like 3D printing are assisting us in developing our own dimension-sensitive bearing systems in our furlers. Solid modeling tools and Finite Element Analysis allow us to bring products to market faster and thus cheaper. At Colligo Marine we understand the intrinsic value of new technology. We grasp it. We nurture it. We cherish it. We are continually searching the globe for new and better materials and manufacturing methods that enable sailors around the world to sail safer, faster, and easier, at a better value.

Dyneema: Lashing & Splicing

A word about our splicing instructions:

For the "do it yourselfers" we want to make sure that you have the information to assemble your rigging in a way that allows you to get the most value out of it in the safest way possible. The US Coast Guard has called our standing rigging "the safest standing rigging that you can buy" and this is really dependent on how it is put together. Our splices have been tested in the lab and on all the oceans of the world and we have a lot of confidence in them, as long as they are done to our high standards. If you are going to use them, please pay attention to the details and, together with our hardware, you will get the safest standing rigging in the world.  Please let us know if you have any questions.

One of our biggest challenges at Colligo Marine is re-educating both the sailing public and professional riggers on yacht rigging principles. Designing a standing rig using Colligo Dux is a fundamentally different exercise than designing one in wire, and this conversion is what gets most folks confused. Furthermore, when using the design parameters meant for wire on a Dux rig, things start to go wrong, customers are unhappy and expectations are not met.

We aim to use this space on the website to provide the information needed to clarify these fundamentals and provide the technical reference material needed for both professionals and DIY'ers alike to succesfully implement Colligo Dux and Colligo hardware onto their sailboats.
