I still remember LEGENDARY UWE HOHN - the best javelin thrower on the earth - that throwing the javelin 104.80m on 1984 in Berlin. http://www.uwe-hohn.de/htm/frame.html
Wow what struck me was his size. He looks pretty huge compared to the throwers of today. A quick search returned that he was 1.98m tall and weighed 112kg. Certainly alot bigger than throwers like Zelenzy and Makarov who have thrown great distances. Just a question, how far could Zelenzy have thrown the old moldel javelin if his current world record is just over 98m?
I remeber reading somewhere, it was a reliable source, that the modern Javelin of today is desinged to go 5-10m less than the rough tail Javelin which Uwe Hohn and the guys of his ear used.
From this we can work out that Jan would be throwing between 103.48-108.48m(!).
Although the literature was reliable, these estimations seem a bit out of range even for Jan!

you may ask kurt francis or mark... they know better that why old javelin was change in new model

Wow! My name was mentioned without me even prompting a response!
I'm just old enough to have had some experience with the pre-1986 javelin; however, I was not an experienced thrower at that point, so my "feel" for the differences is limited. The primary difference in the design (and here goes the fluid-flow lesson) is that the distribution of the surface area (by means of varying the diameters of the shaft along the length of the javelin) was changed so that the center-of-pressure (that point along the length of the javelin at which all the forces on the javelin at any one point in the flight) was changed so that regardless of the speed or angle of attack (angle of the javelin body relative to the trajectory line of the center-of-mass at any point in the flight) never moves in front of the center-of-mass along the javelin. In other words, the aerodynamic forces on the javelin cause the javelin to constantly want to pitch over. The case with the older javelin was that when it was thrown fast enough (minimum speed needed was approx. for 200' throws) and the correct angle of attack, the center-of-pressure would stay foward of the center-of-mass, thus creating what used to be called a "glider" javelin. In other words, the nose of the javelin would stay high relative to the path of the center-of-mass. It would "float" for some distance along the path of the throw. Petranoff's world record 327'2" (I saw this on TV in '83) attained this condition, as well did many world-class throws of that time. I miss those days!
I know this was a long-winded answer, but it's about as concise as a technical guy can make it!

That would make it land relatively flat as well wouldn't it?
Also a few athletes were pondering, would the women not be better off throwing the 700g?
With the javelin world record being a tad under 99m, what would be the estimated maximum range of the new model javelin? I'm sorry I got lots of questions, but I know some people would have answers.
Of all the things we saw at the '82 European Championships (including multiple World Records), I'm not sure anything made much more of an impression than seeing Hohn for the first time. This was September and he had just turned 20 in July and had never competed outside of the DDR. One look at that incredible hulk and we turned to each other and said, "We've just seen the future of the javelin."
