What this video covers
The crew continues the custom build of their 62-foot aluminum expeditionary catamaran, focusing on finishing the aft cockpit and installing safety and utility hardware. To prevent oxidation and maintain the aluminum finish, the team sands the cockpit surfaces and applies Nialic, a clear polymer coating.▶ 6:48 They install LED lighting strips for ambiance and permanently mount roof panels, a sink, and a barbecue grill.▶ 9:48 The team also installs Rutgerson hatches for storage access, carefully orienting the hinges to facilitate loading dive gear directly into the dinghy.▶ 10:41 To meet CE Cat A safety requirements, the crew fabricates a custom aluminum stern gate, ensuring it meets the 600mm height standard.▶ 13:53 Finally, they install a Vetus PL751 port light, using a process of taping, sanding, applying adhesion promoter, and sealing with Bostik adhesive to ensure a watertight fit.▶ 17:33 These installations mark the transition of the aft cockpit from a design concept to a functional living and entertaining space.
