The rings are precisely measured to fit the exact place on the yard where it’s supposed to go. They are heated to 800 degrees Celsius in an oven, carried over on hooks to the yard, then pushed and pounded into place, and shaped with big sledgehammers. This involves fire, smoke and a lot of work. Finally, the rings are cooled down with water, which shrinks them, and fixates the different parts of the yard.
This is a rare piece of craftsmanship, as it’s only done when building new yards, bowsprits and masts. Götheborg is one of very few ships in the world that use this technique.
Do you want to know more about how it’s done, and why, this is explained by our bosun Marie-Louise Edholm in this video clip on Instagram.
