What this video covers

The plumbing installation for the new aluminum catamaran focuses on serviceability, reliability, and centralizing critical systems to avoid bilge-mounted components.0:46 The design routes freshwater and blackwater lines through dedicated bulkhead through-fittings rather than cutting individual holes, maintaining structural integrity while keeping hoses organized.6:24 The freshwater system utilizes a central locker to house a single pressure pump, allowing the crew to draw from either the port or starboard 450-liter tanks and incorporate rain catchment.7:45 To prevent bilge contamination, tank vents are routed high above the waterline.7:19 The blackwater system features 80-liter Vetus tanks mounted above the waterline to allow for gravity-fed discharge, controlled by an electric valve from Forespar.13:44 By upsizing the blackwater drain lines and enabling dual-source flushing with fresh or salt water, the design aims to minimize calcification and clogs.10:14 Routing the blackwater vent to the underside of the hull prevents odors from accumulating on deck.14:40
