Old Ironmaker Posted July 26, 2016 Report Share Posted July 26, 2016 (edited) Somewhere I found a chart that tells you how far the horizon is at ground level looking across the ocean or large lake. Any idea as to where to find it again?I'm here all day bugging everyone as my wife took my truck and her car is in the shop. Being without a vehicle sure sucks when the closest civilization is 10 K away and I'm walking on crutches because I don't know why my foot is swollen and hurts like stink. There is water I can fish in 40 feet from the deck and I can't walk down there! Plus I can see the fish!!!! That's brutal."Fibre Malaysia" is Latin for "we don't know why it hurts, take these pills and go away".

Old Ironmaker Posted July 26, 2016 Author Report Share Posted July 26, 2016 I found it boatsafety.com. Calculating water horizon. Calculate the distance to your eye line plus the height off the water. So a 6 foot person standing in the boat say is 9 feet. Take the square root of 9 (3). multiply 1.17 X 3 = 3.51. The waters horizon is 3.51 nautical miles. Link to comment Share on other sites More sharing options...
kickingfrog Posted July 26, 2016 Report Share Posted July 26, 2016 Water, like the land, is flat so it's infinite. lol Link to comment Share on other sites More sharing options...

netminder Posted July 26, 2016 Report Share Posted July 26, 2016 (edited) assuming the earth is perfectly spherical, the average radius of the earth is 6.371 million metres. Therefore, the distance you can see out into the water is calculated as D = √(12,742,000x -x²) where x is your optical height above the surface of the water. If you're eye level is 6' (1.8m) you can see 4,789 m out into the water. Old IronMaker is probably right, but I'm more accurate Edited July 27, 2016 by netminder Link to comment Share on other sites More sharing options...
grimsbylander Posted July 26, 2016 Report Share Posted July 26, 2016 How far can you guys cast?? Link to comment Share on other sites More sharing options...
kickingfrog Posted July 26, 2016 Report Share Posted July 26, 2016 On a side note today they were talking average height. The average Canadian man is 5'10" so figure an average eye height closer to 5'7"ish for us Canucks. Link to comment Share on other sites More sharing options...
dave524 Posted July 26, 2016 Report Share Posted July 26, 2016 The view of the Toronto skyline changes quite a bit from standing at the waters edge here in Grimsby to the lookout on top of the escarpment, probably a distance of 40 miles. Link to comment Share on other sites More sharing options...
Fisherman Posted July 27, 2016 Report Share Posted July 27, 2016 Oh, so that makes sense that small boats "disappear" under the horizon line even though I see what's perceived to be the shoreline about 10km away. Link to comment Share on other sites More sharing options...
wormdunker Posted July 27, 2016 Report Share Posted July 27, 2016 I don't really care! I'm 5' 11". Does that mean I can't cast further than the guy next to me who is 6" 1"?? LOL! Link to comment Share on other sites More sharing options...
