Two huge pipe wrenches. The trick is to somehow imobilize the shackle. If I can get the whole mess into the dinghy, I jam one wrench under my leg. If not, then I jam the shackle wrench on the mooring ball, so I won't turn. Then crank on the wrench on the pin.... Might be a good Idea to put lanyards on the two wrenches!
