Hi Michael, of course you and Skip are right, I was thinking with half of my brain of Red Sea waters and others places alike, like coasts with an very articulated coastline. Forgot the sea at my frontdoor ( well, somme milews, still) where at some palces in Denmark you should have somebody in a boat to avert fisheremn from trawling tight over your had, diveflag or not. Places where you easily go in from the shore. In the North Sea I have seen the devastated grounds after mussle-harvesting, and seen them before. Still a big difference to banks where fishermen must keep distance from because of big rocks, there is the real life. Other places are like midwest farmground, with similar soil problems. because of thew dragging. Matthias Michael Barnette schrieb: > > Hi Matthias- > > >This comparison fails.
