Hello all

I own a 17ft half cabin boat which weighs around 800kg. I currently have a
traditional sand anchor (sized correctly for the boat) with around 2 meters
of light chain attached to it.
I anchor the boat on in an area of beach type sand, trying to always let out
about 5 times as much rope as the water is deep. On all but calm conditions
the anchor will drag, even after diving down and digging it in by hand. I am
considering buying a plough anchor in the hope of superior holding power. I
have been told the sand anchor should be as good as any in sand and perhaps
a heavier chain would help.
Any thoughts or experiences with different anchor types would be greatly
appreciated.
