It worked

The replacement circuit board, flung onto the ship last night, has worked. We are now being propelled by two propellers on the two Azipod units.

So we are now trying to make up a bit of time on our journey to Cadiz. We had originally planned a speed of 9.7 knots for the passage but with only one engine we had been making only about 7 knots.

Now we have been up to 12 knots so should arrive only 24 hours later than planned.
