What this video covers

Sven Yrvind fabricates a new mast holder for his 30-year-old composite sailboat. He uses a disc matching the diameter of the mast holder to drill precise guide holes, ensuring the geometry of the elliptical surface remains accurate.▶ 0:08 The construction utilizes epoxy and vinylester, which show no signs of rot or water damage despite the vessel's age.▶ 1:56 To release the molded component, Yrvind applies 70 kilograms of weight using a custom friction hitch to pull the piece free from the mold.▶ 3:05 He refines the process by leaving a small margin of ply material on the exterior of the new part to improve grip and structural integrity.▶ 4:10 The hull remains in excellent condition, confirming the durability of the composite build. By locking the joints during the layup process, he prepares the mold for the next iteration of the component.▶ 4:40
