Really?
I suppose that was one use for the fuel out of my Stuart turner. Because it never got used for running the engine-- It never started.
Note the flight engineers head in the foreground. Typically at this point he would be doing everything he can to put off the poor nav. I would expect he was poking said officers arse with a pencil as this shot was taken
Actually, I never did use the 2-stroke oil on a boat either.I suppose that was one use for the fuel out of my Stuart turner. Because it never got used for running the engine-- It never started.
So like you I never used it on the boat- The fuel that is
I'd bought a couple of defunct Seagulls- stripped and repaired them out of interest and ran them in a wheelie bin. The state of the water was shocking compared to running a 2.5 HP Suzuki in the same wheelie bin,
Not a single post has shown what I said to be wrong. Lots of blustering, opinions and quoting of advert text, amongst changes of context, but nothing to actually address what I said. There are people acting like politicians here, but it's not me. Avoidance of topic is the speciality of politicians.
Submariners would consider that without operating a noise maker and firing white smoke candles to go 'yoohoo, over here' 5 miles is for crab air quite close......Just to add a little levity to the situation. Back in the 1990's I was guesting on another Nimrod crew during a "prestigious bombing competition" the target was a submarine. The highly skilled tactical crew including no less than 3 navigators on this occasion released our dummy load in what was though to be the perfect drop position for it to do it's magic and broadside the submerged vessel. We all sat in excited trepidation waiting for the call of a "hit" but none was forthcoming. Much head scratching was observed as to why no Bang! Until eventually one of Her Majesty's finest navigators admitted that the range was set incorrectly on the tactical display and we were 5 miles off target with the release.
I can admit this because it wasn't my normal crew and I wasn't involved in the tactical part of the operation
They were known as the 5 mile wide club from that day on.
Have you found an alternative navigational use for your Christmas tree decorations?
You would need to download how to use it as well as getting a set of tables.
I'm sorry, but your claim that sextants had a history going back "thousands of years" is incorrect, as I pointed out. Sextants and the closely related quadrant and octant go back only to the 17th or 18th century and are completely unlike previous means of finding the altitude of a celestial body; they marked a step change in the attainable accuracy of ship-borne observations. The only one that can be said to go back "thousands of years" is the kamal (it's suspected that the Vikings used something similar, but they were in contact with the Middle East through the Russian rivers and the Byzantine Empire), and a) that can only provide a means of determining when you're on the same latitude as a previously observed location and b) is unusable when the elevation of the observed body exceeds around 60 degreees; it is necessary for the horizon and the observed body to be in the same visual field (60 degrees may well be a very generous estimate). The Crossjack and Backstaff could be calibrated with degrees, so you could determine your latitude using them. But the calibration was difficult, being highly non-linear (I think it goes as the tangent of the angle, but I'd have to draw a diagram to make sure). They also both suffered from the same problem that the horizon and the object of interest had to be in the same visual field, which places severe limits on the range of angles that can be measured.
Both horizon and the object being observed would have to be in the field of view.
