I'm trying to calculate the impact of the speed issue on the Trans Atlantic route.
If I'm interpreting the previous posts correctly, the loss of the generator will reduce the speed by 3 knots. From Wikipedia the maximum speed is 21.5 knots. Assuming they are planning on a speed of about 20 knots the first leg of the cruise to the Azores from Fort Lauderdale is 2,824 Nautical miles. At 20 knots, this would be 5 days 21 hours. At 17 knots, it would be 6 days and 22 hours.
Let me know if you see any mistaken assumptions.
