Crewman wrestles water tank into tight V-berth space
What this video covers
Dan and Kika of Sailing Uma install custom-designed, thermoplastic-welded water tanks into the V-berth of their boat.1:08 The two tanks provide a combined capacity of approximately 250 to 260 liters.1:58 To accommodate the tanks, the pair cuts a larger access opening into the V-berth platform, as the hull curvature prevents sliding the tanks in through the original, smaller hatch.20:26 They construct a rigid internal frame using plywood, glue, and epoxy to secure the tanks against movement caused by the weight of 250 kilograms of water.25:08 The design includes staggered ports for inlets, vents, and pickups to simplify plumbing runs.31:48 Additionally, the crew installs a custom 60-liter holding tank in the head, positioned above the waterline to allow for gravity discharge.33:22 They build the surrounding cabinetry around this tank to ensure it remains removable for maintenance.33:48 The project prioritizes structural stability and system redundancy while maintaining accessibility for future repairs.
