You have me there JS. Assume 15 knots, any faster and almost a tie. Some approaches, like Port Said, for example, we were lucky to not run up the beach before seeing any sort of land mark. Pity that someone pushed over the Alexandria famed lighthouse centuries ago !
Re: Manchester to Chicago
Usually what we used to call Tramp Ship types with no major company behind them who would allow them to leave cargo or skip a port call to make it out if early freeze up began unexpectedly. I will look through some of my old papers for a few names and get back to you. This site is so good there must be a few quiet ones with information just waiting to jump in with good stuff. Cheers.
Re: Manchester to Chicago
They used to tend to drain some of the locks during the freeze up season. Was told that even motor cars had been found in same. The maximum draft in the Welland Canal was either 27 ft 6ins or 25 ft. 6 ins. Can’t remember which. And inspectors used to follow the ship through , if this draft was exceeded there were extremely high fines and even have to be denied entry . The last time I was through many moons ago was on a 33 ft loaded draft 32000 deadweight ship so one can imagine how slack the holds were and a half a degree list was about an increase of 4 inches on the draft , I finished up once arguing about 1 inch overload and got away with it being due to the expansion of the metal due to the air temperature. Or something weird. we used to top up in Trouse Rivierres or better known as 3 Rivers. JS
Re: Manchester to Chicago
#11. Height of eye of a ships bridge say 36 feet then the distance of the visible horizon is only 6.918 nautical. miles . The Alexandria lighthouse would of course be visible at a much further distance . Most people think that the further distance one can see by height is much greater than it really is . JS

Yes that pretentious Pharos of Alexandria was SUCH a pushover,Keith!
Re: Manchester to Chicago
When approaching from the Red Sea end , you were quite likely to see ships upside down well above the horizon due to the extreme reflection and refraction in that part of the world , and would more than likely think it was time to stop having that snifter before hitting the bunk at night . JS
Re: Manchester to Chicago
Hitting the bunk at night without a snifter is not allowed in my house.
Mate who once sailed ocean racing yachts told me the horizon from the beach is only about 5 miles.
But too far to walk to the pub for a snifter.
Re: Manchester to Chicago
He’s near enough right John if your 9 ft 6 and three quarter inches tall. And it’s not foggy JS. To be a little bit more accurate a 5 ft. Pair of stilts could be useful JS
Re: Manchester to Chicago
So maybe we then settle for about 4 miles or would it be better in kilometers.
Re: Manchester to Chicago
When on a ship I always stuck with nautical measurements so maybe by the mark one may suffice. Or maybe and a quarter less two . If a midget at 4 feet , and being a short ass had its disadvantages and the visible horizon would only be 2.306 nautical miles. So don’t discard the stilts . Cheers JS
