Down to the last four but still trying!
1111 FiB (I am too old to have done binary numbers but could this be "Fifteenth in binary"?
71 DatWwEM ( someone suggested this could be "71 days at the wheel with Ellen McArthur" but I have tried everywhere to verify with no luck)
I will keep trying with the other two over the weekend but may have to get back to you clever people Many thanks for your time and help.

I don't know if this is the answer they are looking for, but can confirm 1111 is Fifteen in binary

1111 is fifteen in binary alright, as follows:
= (1x1) + (1x2) + (1x4) + (1x8) = 15

[crofter]

1111 is binary code for 1+2+4+8 = 15
Your answer should read "Fifteen in Binary" (not FifteenTH)

My thanks to all who answered. Although I had already found the "Ellen McArthur" site it only says one of her voyages was 71 days plus. I thought a ditloid would be the title of a book, saying etc. Many thanks.
