What this video covers

Construction of an aluminum expeditionary catamaran reaches a critical phase 10 weeks into the build, with the team preparing to flip the hull.0:06 The vessel is being built upside down to simplify welding and plate assembly.0:24 During the process, the team encountered a 5mm gap between hull plates where a 1mm gap was intended, a result of material thickness increasing from 5mm to 6mm and subsequent plate shrinkage during the wheeling process.5:36 To bridge the gap, the team uses TIG welding for its heat control, while MIG welding is used for the interior seams.6:34 The project lead suffered a back injury, likely a slipped disc, which temporarily halted his participation in the shop work.10:37 During his recovery, the team shifted focus to interior design, specifically optimizing the galley layout for storage and weight efficiency.12:22 The design process involves drafting layouts to replace the deep storage and bottomless bilges found on their previous boat, with plans to convert these designs into CAD files for fabrication.17:15
