What this video covers

Sven Yrvind reports persistent, unexplained water ingress in his boat, forcing him to cut into the hull to investigate the source of the leaks.▶ 1:43 While troubleshooting the hull integrity, he begins constructing a new rudder using a high-density Divinycell foam core with a density of 350 kilograms per cubic metre, a material typically used in submarine construction.▶ 3:07 He glues the foam sections together and prepares to finish the rudder with fibreglass.▶ 3:50 The narrative shifts to a 1974 passage from Tristan da Cunha to Jamestown, Saint Helena, aboard his boat, Breeze.▶ 4:55 During this 1,700-mile winter voyage, Yrvind encountered heavy Southern Ocean swells and violent rigging vibrations.▶ 8:56 He describes a mid-ocean collision with a large, soft organic mass—likely a whale—during a moonless night, which caused the boat to lurch violently.▶ 10:42 Despite the impact, the triple-laminated hull remained watertight.▶ 12:03 He notes that the Tristan islanders had previously warned him about these large waves and creatures, advising him to seek shallow water to avoid them.▶ 11:09
