What this video covers

The crew at Stradbrook Yachts tests the hull integrity of their new aluminum catamaran, Delos 2.0, by intentionally flooding internal compartments with water.0:02 To verify the quality of the hull weld seams and internal bulkheads, they fill the fuel tanks, water tanks, and forward sections with approximately five tons of water.10:46 The team opts for this hydrostatic pressure test over costly non-destructive methods like X-rays or ultrasonic testing, which they deem impractical for the entire vessel.12:25 After allowing the water to sit for four hours, they perform a visual inspection of all seams and penetrations, confirming no leaks.19:34 The build process also includes installing six bilge pumps, transitioning from fillet welds to butt welds at the keel to prevent debris accumulation, and fitting custom rubber seals and weldable hinges to the engine room hatches.9:04 The successful water test confirms the structural sealing of the hull compartments.20:04
