What this video covers

Sven Yrvind evaluates the structural integrity of a composite keel attachment compared to traditional keel bolts for his boat, X-Maxx. He calculates the holding force of an epoxy-bonded joint by applying a shear strength of 2.24 kg per square centimeter across a 1,000-square-centimeter surface area, resulting in a theoretical capacity of 22,400 kg.▶ 2:09 Adding fiberglass reinforcement along the 1.5-meter keel length on both sides contributes an additional 15,000 kg of strength.▶ 3:19 This combined 37,000 kg capacity far exceeds the 75 kg weight of the bronze keel.▶ 3:28 Yrvind performs surface preparation on the bronze by polishing and countersinking the mounting holes to ensure a clean bond.▶ 0:08 He concludes that the epoxy-composite method provides significantly higher holding force than the static load requires, rendering traditional mechanical keel bolts unnecessary for this specific design.▶ 4:07
