¿Qué cubre este video?
Testing confirms that a sharp leading edge on an anchor shank significantly improves holding power in cohesive or structured seabeds, such as clean sand and sandy mud.11:35 In soft mud and cobble-sand, the sharpness of the shank provides negligible performance gains.11:59 To isolate the variable, a Rocna roll-bar anchor was modified with a V-shaped fairing compound on its leading edge, while a Vulcan anchor—which features a factory-sharpened shank—was blunted using slit hose and tape.1:33 In clean, loose sand, the sharpened Rocna increased holding from 380 to 480 pounds, while the blunted Vulcan suffered a major loss in holding capacity.8:34 The upcoming Rocna Mark II will incorporate the Vulcan’s sharp-edged shank design.12:57 Separately, maintenance on Panope includes fairing the keel aperture and rudder for improved hydrodynamics, installing a new fuel day tank, and implementing a battery disconnect switch to isolate the engine block from the DC system.13:45
