Ce que couvre cette vidéo
After a nine-month refit, the Tayana 47 CC *Nanji 2* completes its initial sea trials in South Africa following the installation of a new Yanmar 4JH110 engine.1:38 During controlled tests in Hout Bay, the crew monitors engine performance at varying RPMs while motoring upwind and downwind.2:38 Despite the engine running smoothly, the vessel fails to reach expected speeds at high RPM, leading the crew to conclude the boat is under-propped.3:59 The refit also includes a reorganized engine room, where the crew relocated the freshwater pump and the secondary alternator's external regulator to separate electrical components from water sources.8:02 During a subsequent overnight anchorage, the vessel encounters unexpected 40-knot katabatic gusts, forcing the crew to abandon the anchorage at 3 a.m. when the boat struggles to make headway against the wind.25:20 The crew ultimately diverts to the V&A Waterfront in Cape Town to seek shelter and continue testing.26:05 Proper engine-to-propeller matching remains essential for achieving expected performance under load.
