What this video covers

Sven Yrvind proposes using G11 pipe — a high-strength composite — as a telescoping mast, nesting one section inside the next with a third section above that.0:20 The design would route an AIS antenna through the interior of the pipe, protecting it from damage.0:28 He asks whether the overlap between sections should be two, three, four, or five diameters, and invites subscribers with relevant knowledge to answer in the comments.0:37 He also films an unfamiliar tree on his walk to work, describes small hanging elements on its branches, and asks viewers to identify the species so he can research it on Wikipedia.1:44 No resolution to either question appears.
