Message: [QUOTE="Markus Philipp, post: 41917, member: 161989"] Hi Mark, I tried to summarize the mileage from Southampton to New Castle. The points I selected are about 10..15 miles offshore the places I have given. 1. Mouth of Sotn Water . . . . . . 50°49'N, 1°17 W . . -- 2. Selsey Bill . . . . . . . . . . . . . 50°36'N, 0°47'W . . 23 miles 3. Eastburn / Beachey Head . . . 50°36'N, 0°15'W . . 31 miles 4. Dungeness . . . . . . . . . . . . . 50°48'N, 0°15'E . . 39 miles 5. Dover . . . . . . . . . . . . . . . . . 51°05'N, 1°53'E . . 32 miles 6. Great Yarmouth. . . . . . . . . . 52°40'N, 1°55'E . . 97 miles 7. East of New Castle. . . . . . . . 55°00'N, 1°00'W . .174 miles 8. Tynemouth . . . . . . . . . . . . . 55°00'N, 1°24'W . . 14 miles --------------------------------------------------------------------------------- Total: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .405 miles The average speed with 405 miles in 29.5 hours is 13.7 knots. Now we don't know whether she steamed with constant speed all the time. Lets say she made the first 10 miles with 5 knots and the last one as well, then we have 25.5 hours for the remaining 385 miles. 385 miles in 25,5 hours = 15.1 knots. This is the range i would estimate for the last voyage. Markus [/QUOTE]
