Boat sunk at The Narrows this morning

I took Mawson across to Dunalley yesterday for a surf. I went back out through The Narrows early this morning and there were two police ribs there notifying people that a runabout had sunk out on the bar. They'd marked it with a couple of bouys so it was easy to see it's location and it didn't restrict us getting out. Half way through the surf session the bow popped up as it started to get pushed inside the channel. By the time we were heading in at midday it had been pushed inside a couple of hundred meters. Hopefully everyone onboard was ok. It will be interesting to hear what happened? Oh and the surf was great!
