Oi who dropped that anchour on our brand new sub. Someones going to have to pay. We have contacted the various authorities and believe a new paint job is in order.
I'm reminded of spending an offwatch trying to calculate the horsepower provided by the sails that was needed to drive the 24 tonnes of boat I was sitting on along at 11 knots, which is what it was doing at the time.
I seem to remember getting an answer in the region of 500 hp, a figure in which I had absolutely no confidence.
