Sven Yrvind glues two layers of Divinycell foam to the hull and keel structure of his boat to increase thickness and stability. He uses clamps and wedges to ensure even pressure across the bonded surfaces, noting that the adhesive squeezes out uniformly, which indicates a successful bond.▶ 0:04 The process involves adding a 50mm layer of Divinycell on top of existing sections.▶ 4:56 Yrvind adjusts the height of the keel and rudder components, aiming for a 30cm profile to optimize stability while ensuring the keel remains properly positioned.▶ 1:37 He uses clamps with wooden pins to exert high pressure during the curing process, which requires 24 hours to reach 90% strength.▶ 5:31 The construction also incorporates infusion techniques to manage the resin application.▶ 1:14 Yrvind monitors the alignment of pre-drilled holes and surface cleanliness throughout the assembly to ensure structural integrity.▶ 0:31
