Message: [QUOTE="Mark Chirnside, post: 41910, member: 141801"] Markus, (Sorry for my spelling, I am exhausted typing and putting capitals in.) Your maths is far better than mine, I confess. Regarding my table, sorry I didn’t make it clear before. It’s so tricky to get exact figures, what with the various currents and many sources not distinguishing between ‘through the water’ and ‘over ground.’ In my table, I only calculated very rough values for ‘over the ground,’ which is usually given in many books; these are not specifically for the atlantic. As your table is for through the water, that makes a difference; otherwise I am pleased that they are quite similar. For example: for my 74 r.p.m. figure (one not quoted here) Edward Wilding said Olympic was run at 74 r.p.m., getting roughly 21.50 knots; not in atlantic, but somewhere sheltered, as it were. ‘over ground,’ I think that was. For 79 r.p.m. figure: Duncan Haws’ book ‘Merchant fleets’ that deals with the white star, he lists ‘22.82 kts by builder’ for the Olympic. Over ground, I presume. I used various sources for the whole table. Some from Titanic…some from British enquiry…some by my calculation… I am not really that technically-minded and so do not go into exact details in my upcoming book. If my table was changed to ‘speed through water’ going up to 81 r.p.m., the highest figure confirmed for Olympic, which was briefly got on her maiden voyage, our tables would be little differing. At least they weren’t embarrassingly totally different! The 1911 22.48 knot crossing was 134.5 hour new york to Plymouth; I don’t have the mileage. George; BTW, some Olympic crossing times for our research. Mainly taken from ‘Sea Classics,’ February 1956. (‘Westbound 3’ may be number 4 or other, but was during first year.) Westbound 1: 136.6 hr…21.17 kt Eastbound 1: (?)………22.32 kt Westbound 2: 133.1hr…21.72 kt Eastbound 2: 134.5 hr…22.48 kt Westbound 3: 127.5 hr…21.8 kt (rough) Mid-1920 Eastbound: 133.1 hour…22.53 kt. Cheers, Mark. [/QUOTE]

Verification: In which year did the Titanic sail?
