I will not take off in poor conditions as described - my nerves simply would not stand it. Personally I would probably look for at least 600' base and then preferably know the layer was thin so I would quickly be clear on top.
Strange conditions this weekend in the Channel. I went to Dinard Friday afternoon, v.murky haze across channel and no discernable forward vis. Saw the coast at Cherbourg when we crossed it and then vis slowly improved over the last 20 miles or so to Dinard.
Several of our party got stuck in LFAT Saturday when the sea fog rolled in with a 200' or so base, if that. Came back yesterday from Tours in beautiful vis over France and UK, but once again the Channel had a very thin layer of fog from about 2 miles out of Le Havre right back to the coast at Littlehampton.
PS I do have a current IMC rating.
