Each required anchor handling unit is to be independently tested for braking, clutch functioning, power lowering, hoisting and proper riding of the chain through the hawsepipe, over the wildcat (chain wheel), through the chain pipe and stowing in the chain locker. It is to be confirmed that anchors properly seat in the stored position and that chain stoppers function as designed if fitted. Also, it is to be demonstrated that the windlass is capable of lifting each anchor with 82.5 m (45 fathoms) length of chain submerged and hanging free. Where the available water depth is insufficient, the proposed test method will be specially considered. ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS UNDER 90 METERS (295 FEE
