Hva denne videoen dekker
To align the stern tube on a catamaran build, the crew uses a custom-machined, one-inch diameter insert that fits into the cutlass bearing housing.0:20 By rotating this insert 90 degrees and checking for consistent alignment against a bulkhead mark, they ensure the stern tube is centered to prevent uneven wear on the cutlass bearing and reduce friction for the propulsion system.1:12 Once the alignment is verified, the crew preps the fiberglass surfaces with 80-grit sandpaper to bond and glass the tube into place.6:23 The engine template is positioned at its highest extension to allow for future shimming from the bottom if necessary.3:01 Proper alignment is critical to ensure the prop shaft passes through the gearbox and stern tube without side-loading.5:49
The remainder of the time is spent surfing and hiking near Chesterman's Beach and Crystal Cove in Tofino, Canada.10:07 The crew visits Tofino Brewing and the Tacofino food truck while exploring local rocky trails and beaches.14:22
