Crew seals window frame on aluminum catamaran hull
What this video covers
The construction of the aluminum catamaran Delos 2.0 reaches a major milestone as the crew installs the final hull windows, effectively closing the vessel’s exterior.▶ 0:44 The project utilizes 12-millimeter thick PMMA acrylic windows manufactured by Rutgerson in Sweden, chosen for their lightweight, shatter-resistant properties.▶ 5:55 To ensure a watertight seal that accommodates hull flexing and thermal expansion, the installation process requires precise preparation. This includes applying a UV-protecting "banding" strip to the interior of the acrylic and using Prep G+ as an adhesion promoter on the aluminum hull.▶ 9:22 Professional installers from Alfab apply dam tape to establish a consistent five-millimeter adhesive thickness and use construction-grade sealant to bond the windows.▶ 18:55 Simultaneously, the team coordinates multiple trades to install interior cabinetry, wardrobes, and galley components, emphasizing the need for structural reinforcement to handle the momentum of a moving boat.▶ 15:59 Closing the hull protects the interior from dust and debris in the boatyard, allowing for the transition to finishing work.▶ 22:17
