What this video covers

Sven Yrvind installs drain pipes for the overflow tanks on his boat while it rests on its side.0:43 He drills a 25mm pilot hole through the hull using a long spiral drill bit, then manually enlarges the opening to accommodate a 30mm pipe.2:08 To ensure the pipe fits the hull curvature, he calculates the necessary dimensions using a formula involving the diameter, pi, and the square root of two.2:55 The piping system connects the forward and aft overflow tanks, with the pipes exiting through the bottom of the hull.3:13 He selects a smaller diameter pipe to minimize hydrodynamic resistance while the boat moves through the water.1:02 The installation process involves gluing the components in place and cutting the pipe ends flush with the hull surface.3:57
