What this video covers
The crew of Yabá drills and installs through-hull fittings for the head and three bilge pumps while preparing the vessel for launch at a shipyard. To ensure proper drainage and prevent back-siphoning, the team maintains a minimum 6-inch vertical separation between the head's inlet and outlet, or a 12-inch horizontal distance.0:48 When drilling through thick, multi-layered hull planks—some measuring 8.5 centimeters—the crew uses pilot holes to ensure accuracy, followed by a hole saw.6:19 Because the hull thickness exceeds the length of the standard through-hull fittings, the crew sends the bronze and stainless steel hardware to a welder to be extended.8:15 After drilling, the holes are cleaned with ethanol and sealed with epoxy to cure.11:58 The team also tests the bilge pump relay system using temporary wiring to confirm the manual and automatic switches function correctly before finalizing the installation.18:58
