Sven Yrvind modifies the keel configuration on his boat to address concerns regarding low aspect ratio foils and excessive toe-out angles. Initially, the design featured a 20-degree toe-out, which commenters noted would negatively impact fluid dynamics and performance.3:11 Following this feedback, Yrvind adjusts the alignment to reduce the angle, citing the importance of aspect ratio in foil efficiency.8:16 The keels measure 28 centimeters in height and 160 centimeters in length.3:59 To ensure a precise fit against the hull's curvature, Yrvind uses a template-based approach, sanding the mating surfaces and utilizing epoxy to fill remaining gaps.4:48 He plans to bond the foils to the keel structure first, then secure the entire assembly to the hull.8:00 The process involves iterative trial runs to verify alignment and fit before final bonding.
