My Rocna anchor is fantastic, but it always seems to come up into the stem head roller the wrong way round. This looks like the effect of the water flow over it causing it to turn over. Does anybody else recognize this problem?

Hi NeilM,
Yes, keep putting anchors on the bow till the “experts” on the marina docks and at the yacht club bar chuckle. Then you know you have nailed it. Weight in the anchor is weight more powerful in boat safety than weight put anywhere else. I have a 35kg Spade for my 40 foot boat. That said, anyone who says they have never dragged anchor has likely not anchored much.
Motoring astern in the way you describe has the added benefit of helping to clean the new generation anchors who often come up encumbered with embedded sea bottom.
