What this video covers

After striking a submerged log at 11 to 12 knots, the owner of a catamaran performs extensive in-water repairs in Tampit Garam, Sorong, Indonesia.0:33 The impact bent the starboard propeller shaft and damaged the rudder shaft, necessitating their removal while the vessel remains moored.8:15 To facilitate these repairs, the owner removes the starboard engine mounts, the gearbox, and the dripless seal assembly.14:34 A local machine shop in Jakarta is fabricating a replacement 316 stainless steel propeller shaft, which is more cost-effective than straightening the damaged original.17:54 Additional maintenance includes reinforcing the aluminium gantry walkway with angle aluminium and replacing rusted trampoline grommets with heavy-duty stainless steel versions.10:29 The owner also plans to have a local technician inspect the gearbox to address a persistent whining noise and engagement issues.15:43 Performing these repairs in the water avoids haul-out fees and scheduling delays while the vessel is immobilised with only one functional engine and rudder.1:35
