Oh about erm three feet deep I reckon they were, I mean to load up er eight hundred tonnes, which we average these hoppers out at, er er we were getting a good soil we'd load up eight hundred tonne in an hour and a half to two hours, between hour and a half to two hours we'd be loaded, that's all depend on what you was dredging, you might be interested in  and, and go quicker, if you were dredging greenfly that's be alright you'd, if you dredged peat well that hopper would be full but it wouldn't be half lo it'd be half loaded you see, be half way down to the plimsoll mark.
