Quick, where's the anchor

Many years ago was on an icebreaking tanker (39,000 ton) travelling downstream on the St Lawrence when we suffered total electrical failure .... which took out the steering. The engines stopped but that of course meant you couldn't slow down and we were probably doing about 12 knots with the current. dropped an anchor shortly followed by the second. we ran out all the chain on the first one and the bitter end went. we just stopped a few feet from a ferry dock (with the ferry there as well) ...... hairy ...... just standing watching it when there is bugger all you can do is .......... not nice
