What this video covers

The owner of the catamaran Learning By Doing repairs cracked and broken aluminum welds on the trampoline support gantry while anchored in Lembar, Lombok, Indonesia.0:39 The trampoline system uses a bolt rope track that had failed, causing the netting to flex and pull away from the frame.0:39 After removing the Dyneema lashings and the fiberglass deck cover, the owner transported the aluminum gantry to a local boatyard in the Lembar river to have the tracks re-welded.9:05 The repair process involved grinding down old welds and straightening the track, though the thin aluminum material proved difficult to weld without burning through.9:54 Reinstalling the assembly required two-person teamwork to align the bolt ropes and secure the through-bolts.11:19 The owner concludes that the bolt rope design is overly complicated and prone to failure compared to a standard four-sided lashing system, noting that he intends to replace the current setup with simple lashings if the welds fail again.15:10
