What this video covers

Hanneke Boon, co-designer of the Wharram catamaran being refitted by Arthur, inspects the ongoing structural repairs and provides technical guidance on beam construction, rigging, and hull maintenance.9:02 Boon evaluates a previous beam repair, noting that while a 5:1 scarf joint is the preferred standard for structural integrity, the current repair remains sufficient because it only replaces a third of the beam's cross-section.12:05 She advises using polyurethane foam and fiberglass to seal unused centerboard slots to prevent turbulence and water ingress.14:32 Regarding chain plate mounting, she recommends drilling out existing holes to inspect for internal rot before filling with epoxy and redrilling.20:42 Boon also reviews the mast and rigging configuration, suggesting that the boat’s wide beam may eliminate the need for traditional spreaders, and provides specific measurements for mounting the motor boxes to accommodate the vessel's high beam placement.31:05 The consultation confirms that the boat’s overall structural condition is sound, easing concerns about the refit process.32:00
