Hi Maureen, John!

Adding some of my own thoughts for variety(!

You asked: When Titanic left its last stop and headed for the open ocean, what were the total number of expected miles to be traveled?

I'd guess 2,894 miles, as that was Olympic's maiden voyage mileage (or 2,889 miles); the former fits perfectly her average speed. That's from Daunt Rock to Ambrose Light.

How many did they travel each day that is reported?

484 miles (April 11th start until April 12th noon)

519 miles (April 12th noon until April 13th noon)

546 miles (April 13th noon until April 14th noon)

260 miles (April 14th noon until April 14th 11.40)

Speeds are (respectively) 20.5 knots, 21 knots, 22.1 knots and 22.3 knots over the ground. Adding these numbers up we get 1,809 miles for the wreck's location from Daunt Rock (I *think* it was), which I understand has been confirmed by experts. So that would leave about 1,085 miles left.

(The first 386 mile figure commonly reported, e.g. by Eaton & Haas, cannot be correct. If it was, Titanic would have needed to maintain 30 knots from noon April 12th to April 14th 11.40 p.m. to get to where her wreck is!)

How many does that leave from that last position to get to NY? to get to Sandy Hook?

It seems 1,085 from the calculations I've seen, which roughly seems to fit in, but otherwise that's a rough estimate based on Olympic's mileage.

Just some of my own thoughts:

Titanic could have made April 16th 4 p.m. *if* she had made about an average of 22.65 knots over the ground from Queenstown to New York; but the longer they left it to accelerate sharply, the further the arrival time slipped away from Titanic's grasp. I'd say 8 p.m. New York time was possible for an arrival at a good full speed, at Ambrose light. (Olympic once got in at 10 p.m. in 1911.)

If there was an attempt to beat Olympic, it must have been based on her maiden voyage time, because Titanic was lagging far behind Olympic's fastest crossing. As far as I know, Olympic's record for a daily run was 23 knots over the ground westbound when she burned coal, and 24.01 knots over the ground westbound when she was given oil in 1919/20.

Best regards,

Mark.
